How often do you need to change the gearbox oil on a VAZ 2114? (solved)

Many car enthusiasts believe that when changing the oil in the gearbox of a VAZ-2115, you should pour, as in all other situations, a special transmission fluid. But it is not so. Some front-wheel drive cars are equipped with gearboxes that are combined with the main gear. The manufacturer recommends using motor oils in them. They have spur gears, which means there is minimal risk of scuffing. There is nothing complicated in the replacement procedure itself. You should be guided by the mileage, condition of the car and its reaction to changing gears with the gearshift knob.

If you want to save money, it is better to use mineral oil.

Oil groups

Spectrol-Forward

For domestic VAZ 2115 cars, different groups of transmission oils are suitable, namely:

GL-4
GL-5

The first is suitable for gearboxes of front-wheel drive VAZs, and the second is universal and suitable for almost all domestic cars. Some people believe that GL-5 oils are better than GL-4, but this is not true.

These classes are simply different from each other, and none of them are better or worse than the other. For example, in some gearboxes, API GL-5 oils can have a detrimental effect on synchronizers, while API GL-4 is perfect for them. Oils for the VAZ 2115 GL-5 gearbox can be divided into three groups:

SAE 85W90 – mineral lubricants such as Rexol TM-5-18, Norsi and Lukoil TM-5-18;
SAE 80W90 – less thick mineral oils, including Wells TM, Spectrol-Forward, Texaco Geartex EP-C and others;
SAE 75W-90 – synthetics and semi-synthetics: Motulgear, Teboil EP, BP Energear SGX.

Choosing the type of oil

BP Energear SGX

For VAZ 2115 gearbox gears, it almost doesn’t matter whether you fill in synthetic or mineral oil. From an economic point of view, it is more profitable to buy mineral water. When choosing oil for gearbox components, focus on the following criteria:

relative sliding speed;
specific loads that act inside the mechanism.

Depending on this, you need to choose an oil of suitable viscosity and with the right amount of additives (extreme pressure additives are especially important). As a rule, the latter contain sulfur compounds, which under critical conditions cause chemical changes in the metal. The surface layer does not tear out and scuffs do not form, but turns into a thin film, which acts as a wear product. Regardless of the fact that the metal is chemically corroded, overall wear and tear in harsh operating conditions is reduced.

Chemical modification of the oil in the VAZ 2115 gearbox reduces wear of cast iron and steel. Non-ferrous metals from which synchronizers are made do not tolerate the effects of sulfur compounds and begin to wear out under their influence.

What kind of oil to pour into the box of a VAZ 2115

Considering the factory indications that there is no need to change the transmission fluid, the manufacturer does not provide a list of brands that have been tested with this unit and have passed factory tests. Moreover, in fact, the operating manual does not contain the name of the VAZ 2115 gearbox oil recommended by the manufacturer. Accordingly, the owner must independently decide on the type of substance, depending on his financial capabilities and the nature of the use of the machine. There are 3 types of these products on the market:

Mineral substances enjoy relatively low popularity due to the lack of modern additives in the composition, as well as due to mediocre properties in comparison with competitors. These products have, in addition, only two advantages: low fluidity, which is less likely to lead to the extrusion of the substance through the seals at sub-zero temperatures, as well as low cost compared to competitors. Also, certain advantages include a small chance of purchasing counterfeit products, since for unscrupulous manufacturers the production of cheap products is unprofitable.
Semi-synthetic substances are more popular compared to natural mineral compounds due to better characteristics, as well as the presence of modern additives. In addition, these lubricants meet modern quality standards that are developed for modern transmissions. In terms of cost, semi-synthetics are superior to mineral compounds, but are rarely popular among manufacturers of counterfeit products. Possessing low fluidity, such compounds are common among owners whose transmission mileage has exceeded 150 thousand kilometers.
Synthetic materials have the best washing and cooling properties among all transmission oils. Such materials are produced almost entirely from modern additives; they allow long-term protection of the main components and assemblies of the box from natural wear. However, in terms of its cost, this composition is significantly ahead of its competitors, also having a high turnover rate. Thus, if there is fogging or microcracks in the crankcase, the composition will most likely begin to leak heavily from the transmission system.

Selecting the appropriate viscosity

TM5-18

The TAD-17I transmission oil, well known to many owners of domestic cars, is a thing of the past, and it has been replaced by TM5-18. Selection based on performance properties is not everything. You need to be able to determine the correct oil viscosity, and this is a very important choice.

Oils with a viscosity of less than 24 mm2/s at 100 degrees Celsius, i.e. corresponding to SAE class 140, are only suitable for very hot climatic regions. In areas with moderate temperatures, focus on class 90. It is more rational to fill the box with all-season oil, namely:

75W-90
80W-90
85W-90

The latter are poorly suited for Russian winters, 80W-90 can be considered universal, and with 75W-90 liquid you will not have problems even in the most severe frosts. The use of domestic oils, many of which are classified according to API GL-5, causes rapid wear of synchronizers. In this regard, it is better to fill the transmission of front-wheel drive VAZ 2115 with API GL-4 or universal API GL-4/5 transmission fluids.

Do not fill the VAZ 2115 gearbox with high viscosity oil of the 85W-90 type. The higher the value, the stronger the oil film, but it is more difficult for the oil to reach the gearbox parts. A very high value makes it difficult for the synchronizers to function, since they constantly squeeze out excess oil.

How to change the oil on a “tag”

To begin, you will need to arm yourself with the following tools:

wrench 17 or socket;
a container into which the old oil will be drained (this can be a five-liter bottle or an empty canister);
an empty plastic bottle of one and a half liters;
work gloves;
with a knife;
lift;
work clothes;
a special stand (it is placed under the car);
3.5 liters of new GL-4 class oil, which is not intended for gearboxes;
a sheet of plywood, which will be used instead of bedding if the floors in the garage are poured with concrete or laid with steel;

Changing the oil in the VAZ 2115 gearbox is also carried out on an inspection pit, but we will consider the usual option on a jack. Let's get started:

Using a knife, cut out the side of the canister (you get a kind of container for draining the oil);

Oil drain container

we warm up the gearbox (for this you need to drive at least ten kilometers and thus the gears will disperse the heated oil throughout the entire gearbox);
lift the right side of the car onto the lift;
We place a block under the car, on which we lower the car.

Important. It should be remembered that under no circumstances should you work when the car is on a jack.

This applies not only to the oil change process, but also to any other type of activity.

We place a sheet of plywood on the concrete floor of the garage so that most of it fits under the car;
put on gloves;
we climb under the car, taking with us an empty canister and a key for seventeen;
We find a cutout under the oil plug (it is not found on all protections).

VAZ 2115 gearbox drain plug

Important. It is worth remembering that if the cutout is not detected, then most likely you will have to remove the engine protective shell

take a metal brush and clean the plug;
the space around the plug is also cleaned with a rag;
a container or canister-bath is placed under the drain;
unscrew the plug with a seventeen key;
wait about fifteen minutes until the oil is completely drained, and screw the plug into place;
take a plastic bottle and a knife;
cut out the bottom of the bottle;
remove the air filter and intake pipe, first removing the terminal from the sensor that regulates the air flow;
the throttle clamp and crankcase gas pipe are also unscrewed;
then the inlet assembly is completely removed;
the oil dipstick on the gearbox is pulled out (this dipstick is located in the upper part, closer to the car interior);
We install the neck of the bottle in place of the dipstick like a funnel;

Filling the gearbox of a VAZ 2115 with oil

Advice. It is advisable to fill no more than two liters at first. Then check to see if the drain plug under the car is leaking. It is advisable to wait ten minutes and then continue adding oil.

after this you need to put the protection in place;
add the rest of the oil (in total there should be 3.2 liters of oil in the VAZ 2115 gearbox).

It is recommended to add oil using the dipstick. They check the oil level, which should be in the middle, between the MIN and MAX marks on the dipstick. It is advisable that the transmission be in neutral. After adding oil and completing all work, it is recommended to drive the car 15-20 kilometers. After this, check the oil again, waiting about ten minutes. Changing the oil in the VAZ 2115 gearbox, video of the process - the procedure is not complicated. But it will require a little skill and the necessary knowledge.

Gearbox dipstick VAZ 2115

Armed with the information provided above, it is possible to change the VAZ 2115 gearbox oil using photo and video instructions with your own hands without much difficulty. The presented step-by-step instructions introduce the reader to all the basic secrets of changing the oil. Secrets and some important points also help the novice motorist do everything without much difficulty. And the most important thing is the high price, which can be significantly reduced, because services of this kind in car services are very expensive.

Replacement procedure

To change the oil in the VAZ-2115 gearbox, you have everything ready. Therefore, you can safely begin this procedure. The presented instructions for changing the oil will make you clearly understand that there is nothing complicated here. All work can be easily done with your own hands without outside help. If you do not want to take risks or are afraid to service the transmission yourself for the first time, it is better to trust trusted people from a good car service center. But practice shows that the vast majority of car owners do well in garage conditions. Therefore, do not be afraid, but start working.

To change the working fluid in the gearbox, it is better to have an overpass or inspection hole at your disposal. Many garages have it, so there shouldn’t be any problems with access to the bottom of the car.

Place the car on a flat horizontal area. Pre-warm the gearbox and engine to operating temperature. This will allow the oil to drain faster and in greater volume. Stop the engine and remove the negative terminal from the battery.
You need to drain the old oil from the box of your VAZ-2115. It’s not difficult to figure out how to drain the waste. To do this, remove the engine crankcase protection, if you have one. The gearbox housing is located approximately under the front wheels, where the engine crankcase ends.
About 15 minutes should pass from the moment the engine stops. This will allow the transmission lubricant to drain down.
Using a size 17 wrench, unscrew the drain plug. Keep an empty container next to you where the waste will be drained. When the plug is removed, lubricant will begin to flow out of the hole. Act carefully so that the composition does not get on your skin or spill on the floor. Leave a container under the crankcase to allow as much oil as possible to drain from the transmission housing.
In total, it takes from 10 to 15 minutes to drain the waste if you have pre-warmed the machine. If not, then the composition may drip for a very long time.
When all the waste has come out, return the plug to its place. Make sure that it is not deformed and maintains its sealing properties. Otherwise, the plug will have to be replaced with a new one.
Insert a funnel or hose into the filler hole where the dipstick or plug is located, depending on the type of gearbox. If the box is old, then connect the hose to the syringe and start injecting lubricant into the crankcase. Typically this includes about 3.3 liters of fresh transmission fluid. You are unlikely to be able to fill in more than you need, since all the excess will begin to flow back out.
Raise the front of the car with a jack. This way you can pour a little more lubricant into the box, where the dipstick is missing and you have to navigate along the neck. The transmission will not suffer from an excess of the composition, but if there is a shortage of lubricating fluid, problems with 5th gear will constantly arise.

If you go by the dipstick, then for the VAZ-2115 it is optimal when the level is 4 - 5 millimeters above the o. After all the procedures performed, when the drained liquid has already cooled down, be sure to check its sediment. If there are problems with the gearbox, which the car owner may not be aware of due to the still normal behavior of the transmission, metal shavings are found in the sediment. This is a dangerous sign indicating excessive wear of the elements. As a preventative measure, special additives can be used. If the problem is too serious and the chips appear again during the next service, it makes sense to contact a car service center to disassemble and repair the unit.

Manual transmission oil change period and required volume

The manual for the VAZ 2114 car says that the transmission oil must be changed every 60 thousand kilometers. To avoid gearbox breakdowns, you should:

Observe the timing of oil changes in the manual transmission on the VAZ 2114;
Fill in the required volume of oil, observing the liquid level;
Use only a high-quality product to change lubricant;

The instructions indicate that the volume of oil in the manual transmission in the VAZ 2114 is approximately 3.3 liters of mixture. If such signs of malfunction appear as difficulties in shifting gears, noise in the operation of the gearbox, we can talk about repairing the manual transmission. To avoid serious damage, it is necessary to monitor the condition of the lubricant and its level.

The oil for the VAZ 2114 should be changed in a manual transmission when the following symptoms appear:

Recommended vehicle mileage;
Operating conditions and load of the vehicle;
Technical features of manual transmission;
Long idle time of the car;
Poor lubricant condition;
Presence of mechanical chips in the transmission sump.

By following the recommendations of car maintenance specialists, you can avoid serious breakdowns of the manual transmission, which will lead to expensive repairs.

Additional Tips

When draining the oil, be sure to look at it - there should be no metal shavings in it. Its presence indicates improper operation of the gearbox. The issue may be due to untimely replacement of the lubricant or the use of poor quality oil. Under no circumstances should the drained used oil contain metal fragments or other signs of gearbox failure. If they are present, contact a service center or fill in new oil and drive it for about a week. Then drain it and see if there is any new debris in the fluid. Repeat the procedure in a month - if everything is in order, you can drive without contacting the service center.

Finally, we note that you must learn how to operate the gearbox correctly, without inserting gears too abruptly. Otherwise, the engine will not have time to slow down and shifts will be bumpy, which is bad.

Replacement and useful recommendations

The period for changing gearbox oil for VAZ cars is described in detail in the manufacturer's official instructions. It says that the fluid must be changed every 60 thousand kilometers. There are other recommendations that every driver needs to heed.

During operation, it is necessary to constantly monitor the level at which the oil is located inside the gearbox.
Transmission oils should be used only of high quality, recommended by the manufacturer.
Change the transmission fluid in a timely manner as soon as the need arises.

The same official manual indicates exactly how much oil to fill. The minimum required quantity is 3.3 liters.

It is necessary to carefully select not only the composition itself, but also its packaging for the checkpoint. Typically, such liquids are sold in canisters with a volume of 1, 3 or 5 liters. Increasingly, there are proposals to sell bottled oil directly from barrels. This allows you to profitably purchase only the amount of lubricant that is actually needed. The main thing is to pre-purchase the composition in small quantities to check its quality. Otherwise, you will have to spend more on repairing the box later.

Tools and materials

When preparing materials and tools, it is important to consider what type of gearbox is installed on your vehicle. There are two types of gearboxes provided on the fifteenth model from AvtoVAZ. These are old and new style boxes. They are not very different from each other from the perspective of an ordinary car owner. There is no need to go into any minor design or technical differences. The main thing is to understand that on old boxes there is no dipstick and the filler hole is located lower. New transmissions are filled with lubricant using a funnel, but for older transmissions you will need a large syringe and a hose to reach the filler neck. Otherwise, the procedure for changing the working fluid on the two types of gearboxes is identical.

To work you will need the following tools:

key to 17;
empty waste container;
syringe;
hose (about 0.5 meters long);
funnel;
canister with transmission oil;
hexagons;
rags;
protective clothing.

Be sure to take the empty canister and key with you under the car, otherwise without them you will not be able to drain the waste. If your VAZ-2115 is equipped with crankcase protection, then take appropriately sized keys under it to remove it. As additional repairs or maintenance are performed on the machine, an additional set of tools may be required.

Filled volume

An important point is the amount of lubricant poured into the transmission installed on VAZ-2115 cars. It is about 3.3 liters. You already know which fluid is best to pour into the VAZ-2115 and its gearbox. To accurately understand the amount of oil, you can rely on the results of draining the old grease. As much oil comes out, you will pour the same amount back into the crankcase, only with a fresh composition. In the case of the VAZ-2115, the volume of oil in the gearbox is relatively small, which will not require large financial expenses from you to purchase it. Take a 4 liter canister.

In practice, it holds slightly less if the box has not been completely drained, which is almost impossible to achieve in garage conditions. It is extremely important how much oil you manage to pour in so that each gear in the box is covered with a lubricant. You know the problem of the VAZ-2115, so you cannot ignore the rule of maintaining a high level of lubrication. Experienced car owners advise not to buy fluid with a large supply. You will not need it in the near future after changing the transmission composition, and over time the oil may lose its properties and quality. It is better to purchase fresh lubricant later.

When do you need to change the oil in a VAZ 2115 manual transmission?

The VAZ 2115 model is a logical continuation of the VAZ 21099 model, with some stylistic and technical changes. This model entered the market in 2001 and during production until 2011 it managed to sell 600 thousand copies.

The VAZ 2115 is equipped with a classic 5-speed gearbox, which was developed in the late 80s and early 90s. In terms of its design, it appears to be a classic system with a flywheel and gear shift clutches. During operation, no critical comments or major shortcomings were identified. The declared service life of the box is 150 thousand kilometers, but with proper care, constant prevention, and in the absence of excessive loads, overcoming this milestone will not be difficult.

There are well-known cases of “nursing” the transmission and more than 300 thousand kilometers without major repairs and with timely oil changes in the VAZ 2115 transmission. Therefore, in general, such a unit is considered quite reliable.

Regulations for changing transmission fluid are determined by the manufacturer. According to the developers, this gearbox is filled with transmission oil for its entire service life. However, in practice, after covering a mileage of 150 thousand kilometers, this substance completely loses its cooling and washing properties. At the same time, the oil filter also ceases to perform its function, as a result of which a large amount of waste begins to accumulate in the system, thereby preventing the normal operation of the unit. All these factors ultimately lead to complete breakdown of the entire system and, accordingly, expensive repairs.

Therefore, experienced owners independently change the fluid in the box when the mileage reaches 60-70 thousand kilometers. Also, the interval largely depends on the nature of operation and the area in which the car is located. Under constant high loads when driving on highways, when standing in traffic jams for many hours, the VAZ 2115 gearbox receives heavy loads, which also negatively affects the condition of the transmission fluid. Therefore, to extend the life of the unit, the interval must be chosen taking into account negative factors during operation, and the optimal average value is 60 thousand kilometers.

Transmission oil change intervals

Based on factory documentation, the oil needs to be changed every 70–80 thousand kilometers, but at least once every 4–5 years with an average annual mileage of 15–16 thousand km. In reality, the situation is somewhat different - weather conditions, environmental conditions, operating and storage (parking) conditions have a serious impact on replacement intervals.

According to experts, replacement must be done every 35 - 40 thousand km, and at intervals after 30 thousand km. It is already possible that primary signs of violations may appear:

heavy and imprecise gear shifting;
extraneous noise;
vibrations.

If the above symptoms have recently begun to appear in your car, we strongly advise you to change the oil as soon as possible - this will reduce wear on gearbox parts and compensate for possible losses from breakdowns.

Which oil to choose for the VAZ 2114 gearbox?

The driver will love the car provided that the main components of the car work perfectly. The driver knows in advance how much oil to pour into the engine, variable gearbox, and drive axles. But not always, especially beginners, know what type of lubricant to buy, for example, for a variable speed gearbox 2114.

The manufacturer helps you make your choice by offering to purchase products from a short list consisting of three items:

lubricating consistencies with a mineral base;
synthetic oils;
oils, made half of synthetics.

A rational conclusion can be drawn from the above list. There are many good offers on liquid platforms. Following the recommendations of the KOSSS102 channel, it is rational to buy the specified product. Transmission lubricant used for engine valves is suitable.

The fact is that the technical characteristics of the interaction of the elements with each other of the variable speed box and the cam mechanism of the motor distribution unit are similar in terms of abrasion coefficients.

Oil brands for gearbox 2114

In specialized stores, oils with a high degree of liquidity are always available. Sold in convenient containers with different volumes of lubricant product capacity.

Synthetic oil 75W-90 is in good demand. Well protects articulated parts from premature abrasion in heat and cold.
Semi-synthetic 85W-90 is recommended for cars with high mileage.

The lubricant product is packaged in convenient-to-use containers according to the number of liters. Since one oil fill during maintenance requires more than three liters, drivers tend to buy for future use.

A container that holds 8 liters of liquid lubricant is considered a running container. A certain number of motorists may be surprised, they say, why buy such a quantity of consumables. There are different ways to respond to skeptics.

Others cite work commitments that do not allow them to frequently visit specialized stores. It is more profitable to buy a large container with a guarantee of systematic refilling of the lubricant product into the crankcase of the 2114 gearbox than to run around the store looking for oil.

Others always buy something for future use on purpose: they pour as much into the 14th as liters are required. Some drivers change the lubricant after 30 thousand kilometers. In a word, both are individually right.

Brand and volume of oil for gearbox VAZ 2115

The most interesting thing is that according to the regulations, it is allowed to fill the VAZ 2115 manual transmission with motor oil, but with the proviso that the replacement will be carried out as in the engine - once every 10 - 15 thousand kilometers.

But such measures were resorted to earlier, when gear oils were practically impossible to find. Now the range of these fluids is so wide that many, even avid car enthusiasts with extensive driving experience, get lost and take a long time to choose the appropriate transmission fluid.

To avoid confusion and ensure you get exactly what you need, follow these instructions:

The basic rule is that expensive does not mean quality (when choosing, do not rely on price; usually, the more expensive the oil, the higher the likelihood of counterfeiting)
First of all, pay attention to the marking, the viscosity should be 80W-85 or 80W-90
The oil class must be GL-4 or GL-5, which corresponds to the domestic markings TM-3 and TM-4.
For cars of the VAZ family, there are transmission fluids specially designed for them, for example, Rexol T, Omskoil Trans P and Volonez TM4. If you come across these brands, purchase one of them without hesitation.

Purchase any oils only in specialized stores and from official dealers! This is very important to avoid counterfeits.

What kind of oil to fill in the gearbox on a VAZ 2114

Now you need to choose which oil you want to buy for the VAZ-2114. A mistake cannot be made here, since a fluid that does not correspond to a specific gearbox can lead to breakdown or incorrect operation of the part. So, you need to understand which oils you need to buy in the store and which ones the car manufacturer advises you.

There are a few things you need to consider when choosing new transmission fluid:

What type of gearbox do you have: manual or automatic?
What are the weather conditions in your region?

In stores that help in car maintenance, the choice of oils is quite large: synthetic, semi-synthetic and mineral technical oils. It’s definitely not worth taking the latter type, because it has very low characteristics and is often accompanied by poor quality. We recommend choosing synthetic oil, as it copes well with technical tasks, and there is a good review about it.

The problem is different, synthetics are expensive and not everyone can afford them. As a replacement, you can consider a semi-synthetic fluid; it has good characteristics at a fairly affordable price. If you turn to experienced drivers, they advise buying either synthetics 75w - 85w, or semi-synthetics 85w-90w. Do not try to take oil that is characterized by too high a viscosity. This may prevent lubrication and further rotation of the gears!

Operating experience of car owners

We figured out how much oil to pour into the VAZ 2115 gearbox and which one to choose, but now let’s turn to the experience of using different lubricants by owners of domestic cars:

Castrol 75w90 - in the winter months the oil may freeze and the car may not move well in neutral.
Shell Getribeoil EP 75w90 is a good oil that allows you to start your car without pressing the clutch pedal.
TNK 75w90 is a cheap analogue of the previous oil.

The main thing when buying oil is not how much oil is in the VAZ 2115 box or which one to choose, but not to get a fake. Try to buy lubricants only from trusted places.

After choosing an oil, you should read a detailed article on changing the lubricant. We have suitable material on our website, and you can also watch detailed video instructions to understand everything.

How to fill oil into a VAZ 2115 box

The procedure for changing the oil of a VAZ 2115 with your own hands is carried out in several stages:

First you need to lift the car on a lift and remove the metal protection of the engine crankcase and gearbox.
After this, unscrew the oil filter and the special drain bolt and remove the waste material.
After draining the spent substance is completed, it is necessary to use a simple funnel to fill in new material through a special filler neck, which is located in the upper part of the engine compartment on the gearbox housing.
If the overflow is above the mark indicated on the plastic dipstick, the excess volume must be drained by unscrewing the oil filter.

After the change procedure, it is necessary to check the performance of the gearbox by alternately switching all gearbox modes in a standing position. In this case, extraneous sounds arise, the selector lever should switch without additional effort, there should be no grinding or humming sounds, and there should be no manifestation of other negative factors.

How to change it yourself?

The design of the components of the VAZ 2115 car is very simple, so the oil in the box is often changed on its own. To do this you will need tools and no more than two hours of time.

Tools and materials

fresh oil, 3.5 liters is enough;
rags and gloves;
10 and 17 mm wrench (ideally you need a full set, as the protection may need to be removed);
slotted screwdriver;
funnel or transmission syringe;
a container with a volume of at least 4 liters for draining waste.

Stages of work

Immediately before changing the oil in the gearbox, it is necessary to warm it up. To do this, it is enough to drive about 10–15 kilometers.

In order to replace the lubricant in a VAZ 2115 car, you need to do the following:

Place the machine on a horizontal surface. It is more convenient to carry out replacement from a hole in the garage or on a lift.
Remove the protection of the engine trays and/or transmission. The protection does not need to be dismantled if it has a hole that exactly matches the drain plug.
Wipe the lid and box housing around it with a rag.
Check for oil leaks along the parting lines and seals.
Place the container and unscrew the cap.
Wait about 20 minutes for the oil to drain completely.
Screw the cover onto the gearbox housing.
Lubricant can be filled using a syringe for transmission fluids or a funnel with an extension. In the second case, it is necessary to remove the air filter housing; the device is held on by two clamps - the throttle assembly and the crankcase ventilation tube. Since the VAZ 2115 uses an injection engine, when removing the filter it is necessary to disconnect the air flow sensor connector. Some owners remove the absorber tank to make access easier.
Then you need to remove the dipstick from the hole that will serve as the oil filler neck.
Pour 2.8-2.9 liters of oil using a funnel or syringe. When changing the lubricant, a smaller volume of liquid is always poured into the crankcase than the rated capacity of the box. This is due to the fact that some old oil remains inside.
Wait a few minutes and check the amount of fluid on the dipstick. If the level is below o, the oil must be added. Excess lubricant can be pumped out with a medical syringe with a volume of 50 ml or more with a dropper tube attached to the nozzle.
After this, you need to check that there are no lubricant leaks through the drain plug and box components. If traces of a leak are noticeable, then the cause of its occurrence must be eliminated.
If the lubricant was replaced while the filter was removed, the parts should be reassembled in the reverse order.
After 500-700 km, it is necessary to perform a control check of the oil level and the tightness of the unit components.

In the video, user Denis Onishchenko demonstrates the procedure for changing the oil and removing the car's absorber.

Checking the amount of oil in the gearbox

Always check the transmission oil level, and even if you just recently filled in new fluid, you should not forget about it, because the oil level always drops and you need to keep an eye on it. Even a slight decrease in the required volume can lead to a number of difficulties and various breakdowns, due to which the gearbox will cease to function normally. Newbie drivers often don't know how to check the fluid level in their car. Let's take out some pieces of paper and start writing down our tips!

What does a dipstick look like for checking gearbox oil?

A guide on how to understand how much oil is in the dipstick:

First, open the hood and look at the entire space under it to find out where the dipstick is located.
Remove the dipstick, wipe and clean it very diligently and carefully, completely removing old oil stains from the dipstick.
Use a rag for cleaning! It is free of lint and will not end up in your transmission fluid.
Just put the dipstick back and be patient for a couple of minutes.
Remove the dipstick again and carefully examine the location where the oil mark was located. On the outer part of the dipstick you will be able to see the possible maximum and minimum marks.
It is advisable that the oil mark be at the possible maximum mark, since the manual transmission has a gear that is responsible for the operation of the fifth gear, and it is located slightly higher than the others. To ensure the operation of this part, it is necessary that the oil level is at maximum.

The best motor oil. does it exist?

Frequent driving at high speeds
Sharp maneuvers
Driving on bad and dusty roads, including off-road
Temperature changes, when frosts are replaced by sudden warming, dirt and slush on the roads
Frequent engine operation at high speeds, which causes overheating and rapid wear of transmission parts

Russian motorists are well familiar with these so-called risk factors. Knowing about possible problems, they prefer to change the oil twice as often as specified in the regulations - for example, after 50 thousand kilometers. The regulations can be reduced even further if the machine is subjected to increased loads almost continuously. In addition, in such cases, it is advisable to check the volume of oil in advance, and at the same time monitor its condition.

How is the volume of lubricant in the 2114 gearbox determined?

The automobile plant sends its products to liquid specialized sites with a set of instructions for operating the vehicle. Instructional materials regarding transmission units contain specific information.

The practice of operating a car of this modification has shown that the factory instructions cannot be an axiom when replacing a lubricant product. Scheduled and extraordinary maintenance (TO) require less lubricant. That is, a smaller volume of oil is required to be poured into the box. Drivers have empirically determined that it is enough to add 200 milliliters below the factory norm.

The a priori filling of oil by a plant that produces cars of the specified brand is calculated especially accurately. The lubricating fluid has good adhesion. Subsequently, covering the surfaces of the shafts and gears, settling on the walls of the box body, part of the lubricant product remains on these elements during intensive use. A significant portion of the oil in the VAZ 2114 gearbox remains in the form of a thin film. It cannot be drained when refilling.

They say that butter cannot spoil bread. In relation to food, a capacious definition. But not for pouring oil into the transmission unit of a car. When heated, any liquid increases in volume. At the same time, quality indicators decrease. The lubricating product loses its protective properties against abrasion of rubbing parts, contributing to their rapid wear. In short, the VAZ 2114 gearbox should not contain excess lubricant or significant underfilling

To extend the service life of an important transmission unit, you need to know the exact volumes of oil to be filled

Useful instructions will be productive during a certain operational period of the unit. The fact is that during long-term operation, the volume of oil poured into the VAZ 2114 increases significantly due to wear of rubbing parts. They wear out. Particles of waste metal pass to oil mixtures, raising their level. To balance the balance, add not 200 milliliters of lubricant, but 50 or 100.

In principle, the increase in oil level depends on the gear shift frequency. The more often the driver uses the speed change lever, the more intensively the gears, shafts, and splines of the vehicle transmission unit wear out.

What you need to know about choosing the right oil for the VAZ-2114

What kind of oil should be poured into the box of the VAZ-2114?

The manual transmission of this car has long been famous for its durability and reliability. But in many ways, the quality of the product depends on you and on the correct choice of lubricant. Firstly, choosing a product for your car can and should begin by considering the oils that VAZ itself recommends for use. These tips are quite easy to find, just find those. documentation that you received when purchasing your car, and find a separate list there that will contain a list of oils and lubricating fluids.

Well, that's all, take and pour what the manufacturer advises, but not everything is so simple. The quality of the offered oils is very often questioned by experienced drivers and car enthusiasts, and this negative review is certainly not without truth. If you look at it in reality, almost always after changing the factory product to an imported manual transmission in a VAZ-2114 it starts working very smoothly, quietly and softly.

The main thing is to consider the right product option based on all the recommendations and advice.

What is the reason? Not all liquids will be able to reveal their functionality to the maximum in the VAZ-2114 box, and some will not even work. Don’t forget about your personal conditions for using the car.

Here's what the VAZ manufacturer can offer us:

Experienced car enthusiasts advise buying transmission fluid from Lukoil.

75 W 90 GL -4 is a semi-synthetic with more advanced characteristics, which is recommended by AvtoVAZ. The oil is a leader in its price category and, in principle, performs excellently at both low and high temperatures.

If you look at the disadvantages of this liquid, then this product has quite a high noise level during operation compared to other mineral-type or semi-synthetic oils.

If you choose 80W90 GL-4 oil, then you will spend less money than on synthetics, and the gearbox itself will make less noise. Well, here, of course, there are some drawbacks:

In cold seasons, the liquid tends to freeze, that is, the gears will not respond well to your actions until the oil warms up.
The product has deteriorated anti-corrosion and protective properties.

If you are not satisfied with Lukoil, then there are several replacements for this manufacturer:

By the way, be very careful when choosing an oil, since professionals in the auto service industry do not advise choosing too expensive synthetic oil or too cheap mineral water for the VAZ-2114 gearbox.

If you look at reality and choose what kind of oil to fill into the box of a VAZ-2114, then proven 75W90 GL-4 oils are best suited for you, you can make an improvised mixture and add GL-5 (you can do this only when you understand why this), but do not think of adding exclusively the second option, it serves only as an auxiliary liquid.

This choice will help your gearbox operate as smoothly as possible, protect it from various debris, eliminate excess noise and, most importantly, bring you comfort on the road.

Even under all these conditions, you will not incur huge waste on lubricant. Expensive synthetics for a VAZ-2114 car are simply not required, since your car does not have a special load on the transmission.

And yet, a very expensive synthetic oil will not last much longer than a mid-price semi-synthetic oil, so it’s better to change the oil several times than to drive an expensive one all the way and ruin your car!

How many liters of oil to pour into the VAZ 2114 gearbox

Your car can hold 3.5 liters of oil, but it is only possible to fill the transmission to 3.3 liters. All this is due to the fact that when the old product is drained, a small amount of liquid remains in the gearbox.

3.3 liters of oil

Oil viscosity. Which one to choose?

Here we come to the end. If you have not yet figured out which oil you will choose, we recommend that you take into account such a factor as the viscosity of the liquid.

Here you should pay attention to the weather conditions in which the transmission operates.

If your winters are not too cold and the average temperature reaches -15 degrees, then you can choose 80W90 without much thought. But if the temperature in your area drops lower, then 75W90 is a good choice.

Bottom line: Take into account the weather conditions and the particular use of the machine when choosing oil. In almost all cases, a product like 75W90 will work for you.

Oil draining process

General view of the gearbox

It is quite easy to completely drain the oil from the VAZ-2114 gearbox. Work must be done immediately after the trip to reduce viscosity. This is due to the fact that it is heated and the density is reduced.

Location of the gearbox drain plug

So, let's consider the sequence of actions aimed at draining oil from the gearbox:

We install the car on a viewing hole or lift.
First, the breather is cleaned.
Then you need to unscrew the oil dipstick.
Place a container to drain the oil.
Unscrew the drain plug.
We wait until the oil drains completely.
In order to fill in new oil, you need to take a funnel and insert it into the hole for the dipstick.
We carry out the assembly in the reverse order.

Features and properties of oil

MANNOL gear oil - recommended for filling into gearboxes

Oil plays many roles in the functioning of the gearbox. So, in order to understand why it is needed, let’s consider the main properties:

Chemical. They play the role of a lubricating fluid, which is necessary for the normal functioning of the components and parts of the car. So, if there was no oil, parts would begin to wear out due to heat and friction, which in turn would lead to the fact that most products would not reach their service life.
Physical. Since the transmission generates a lot of heat when operating, it needs somewhere to go. Thus, oil is a kind of heat absorber that prevents the spare parts from heating up inside the gearbox housing. Also, its lubricating properties form a kind of film, which reduces the degree of wear of products to a minimum.
Technical. These are mixed properties of physical and chemical, namely the prevention of harmful effects on the structure as a whole and its main elements. These properties prevent the occurrence of metal shavings, corrosion and other technical faults.

This is what the oil drained from the gearbox on a VAZ-2114 looks like. Mileage 55,000 km. It still looks like

If the oil loses its properties, then the entire structure and individual elements begin to wear out faster.

Selecting a motor lubricant and oil filter

For the VAZ 2115 Lada Samara 2, the manufacturer recommends lubricant with API quality: SF, SG, SH, SJ and the following viscosity:

Ambient air temperature, °C	SAE Viscosity
from -15 to +45	15W-40
from -20 to +30	10W-30
from -20 to +35	10W-40
from -25 to +20	5W-30
from -25 to +35	5W-40

The type of lubricant is chosen independently depending on financial capabilities. The highest quality is synthetic. It has a high degree of engine protection, prevents the appearance of any deposits, and allows you to easily start the car in cold weather. There is only one drawback - high cost.

Semi-synthetics are very popular and have an optimal price-quality ratio. Mineral oils have the lowest cost, but have high viscosity and provide the shortest mileage before replacement. Manufacturers occupying first places in the ranking: Castrol, Shell, Mobil. But you can use cheaper products from domestic manufacturers.

About 3.5 liters of lubricant are poured into the VAZ 2115 engine. To accurately determine how much lubricant is needed, use an oil level sensor (dipstick).

Choosing an oil filter is not difficult. The main requirements for filters are: tightness of the anti-drainage valve and connections of housing parts. The service life of the VAZ 2115 engine directly depends on this. MANN W914/2 and its full analogue BOSCH P3274 have proven themselves very well.

When using them, the oil pressure sensor does not work, and the emergency oil pressure light goes out almost immediately after the factory. Many drivers recommend the original VAZ Lada Salut filter. If the warning light does not go out at idle, you need to check that:

there are no knocks or rattles in the engine;
the recommended liquid of good quality and in the required volume is used;
The oil pressure sensor is in order (check by replacing it with a good one) and the wiring from it does not short to the housing; if the light continues to glow, then the reason is different, the oil pressure sensor has nothing to do with it.

Selection of gearbox oil for a VAZ 2110

Changing the oil in a VAZ 2110 gearbox requires compliance with basic rules, compliance with which will ensure uninterrupted operation of the vehicle for a long time.

Therefore, it is important to pay special attention to the purchase of liquid

Experts recommend first of all focusing on the originality of the product, and not on the brand. Many automotive suppliers sell low-quality counterfeits under the name of leading brands (Castrol, Mobil, BP). Such negligence on the part of sellers can result in negative consequences for the owner

It is also important to purchase products from official distributors or suppliers with successful experience in the market. A big plus is reviews from car enthusiasts on specialized forums.

Their life experience will help you avoid common mistakes.

It is necessary to select oil for the VAZ 2110 gearbox based on several factors, namely: climatic conditions and the season in which the driver operates the car.

The stores offer lubricating fluids made from:

mineral components;
synthetic materials;
semi-synthetic materials.

Experienced auto mechanics recommend synthetic oil for the VAZ 2110 gearbox, which allows you to effectively use the car even in particularly unfavorable temperature conditions. But the cost of this type of liquid is higher than semi-synthetic. Therefore, for owners who are trying not only to buy a good product, but also to save money, the last option is suitable. Do not forget that it is forbidden to use mineral oil after using two other lubricants.

Before considering the replacement process itself, you should understand the possible reasons for this need. In addition to periodic updating due to the 30 thousand mileage of the car, this is affected by a decrease in the performance of the car or the use of low-quality oil, which causes an atypical hum when changing gears.

What oil is better to use?

To choose the right fluid for the VAZ 2115 gearbox, you need to take into account the factory recommendations. According to the service documentation, it is necessary to fill the box with special gear oil that meets SAE 80W-85 and API GL-4 or GL-5 approvals. This type of liquid is present in the product range of any company that produces lubricants for cars.

At the factory, when the car is released, TNK or Lukoil brand oil is poured into the box. These same fluids are among those recommended by the manufacturer for the VAZ 2115. When operating a car in winter, many owners try to use synthetic oils that meet the requirements of SAE 75W-80 or 75W-90. The use of such lubricants significantly reduces the operating noise of the unit and facilitates gear shifting at negative air temperatures - below minus 16–18 degrees.

Among the most common oils for the VAZ 2115 are the following (in ascending price):

Lukoil TM 4–12 80W-85;
THK Trans KP 80W-85;
ZIC GF 75W-90;
Shell Spirax S5 75W-90.

Which gear oil is best?

The manufacturer himself gives several recommendations on which substance is best to use for the 2115 gearbox. GL-4 - this should be the API composition group for the VAZ 2115. In addition, the requirements for the viscosity class are given. It also depends on what product is chosen and what needs to be poured.

For semi-synthetics, this is the transmission substance 85w90.
For mineral: 80w85
75w90t for synthetics

There are several brands that are specifically recommended by the manufacturer for gearboxes. These are TRNAS KP, Slavneft TM-4, Nordix Supertrans RHS, New Trans KP, Lukoil TM 4-12, Lada Trans KP.

It should be noted that in Russia the API GL-4 group itself is classified as TM-4. That’s why the manufacturer recommends using liquid from Lukoil with similar markings. True, this particular composition does not belong to the off-season. Therefore, this liquid will thicken in severe frosts. Because of this, there is a high probability of problems occurring in the operation of the gearbox. Therefore, it is important to decide in advance which product needs to be poured in a particular case.

A separate set of requirements for fuels and lubricants has been in force since 1998. These rules provide temperature ranges within which fluids operate normally. For example, for 80w85 lubricant this temperature is from -26 to +40 degrees. Therefore, for our country it is recommended to give preference to off-season compounds, which are designated as SAE 75W80 or 75W90. Their upper temperature limit is the same, and the lower one reaches -35. This should be taken into account by those who are thinking about which substance to choose.

Replacement frequency and choice of gearbox lubricant

Depends on the operating conditions of the vehicle. In regions with colder climates, less viscous liquids are used. Oils with high viscosity are better suited for hot climates.

Depending on the season, it is important to consider the properties of the oil used. To better perform its assigned functions, it is recommended to replace mineral oil with semi-synthetic or synthetic oil before the winter period. Synthetics to mineral - before summer.

For long runs, you should focus on the mileage. For a VAZ 2114 car, replacement is carried out at least once every 60,000 km. If the car is rarely used, consider the expiration date of the lubricant. The average is 5 years.
