What gear oil should I put in a manual transmission? Choosing oil for a VAZ gearbox Which oil is better to fill in a VAZ 2110 gearbox

06 May 2015 Lada.Online 509 968 31

The frequency of changing the oil in the gearbox depends not only on the model and type of transmission, but also on the year of manufacture of the car. For example, on Niva every 40 thousand km, and on front-wheel drive LADA every 80-180 thousand km). Let's figure out which gearbox oil is best to choose, and whether it can improve transmission performance and reduce howling.

Separately about

:

• Renault JH3 and JR5 transmission oils
• transmission oils Lada 4x4
• Niva Chevrolet transmission oils.

What transmission oils are recommended by AVTOVAZ ? If you open the Operating Manual for the vehicle and its modifications, not the latest edition, you can find table No. 4 “Transmission oils for gearboxes.” Comparing them for different Lada cars, you can understand that AVTOVAZ recommends the same transmission oils for the Lada Granta/Kalina/Priora gearbox.

• LUKOIL TM-4 - 75W-80, 75W-85, 75W-90, 80W-85, 80W-90; TG-4
• NOVOIL TRANS KP - 80W-85; TG-4
• ROSNEFT KINETIC - 80W-85; TG-4
• TNK TRANS KP - 80W-85; TG-4
• TNK TRANS KP SUPER - 75W-90; TG-4
• TRANS KP-2 - 80W-85; TG-4
• SHELL TRANSAXLE OIL - 75W-90; TG-4/5

What brand of oil is in the manual transmission on Lada from the factory?

• For Lada Priora - Lukoil TM 4-12 (80W-85, 75W-90).
• On the Lada Kalina - Mineral TNK TRANS KP, TU 38.301-41-191-01, which is produced by the Ryazan Oil Refinery (the old name is ROLS T).
• On the Lada Granta - Lukoil TM 4 with a viscosity class depending on the region of operation of the car - 75W-80, 75W-85, 75W-90, 80W-85 or 80W-90. Since August 2012 Fill the front-wheel drive gearbox with transmission oil TATNEFTTRANSLUX 75W85 (semi-synthetics)
• On Lada Largus - ELF Tranself NFJ 75W-80 GL-4+.
• Gearbox 2180x (Lada Vesta and XRAY): semi-synthetic gear oil “Rosneft Kinetic Service” SAE 75W-85 API GL-4.
• JH3 gearbox (Lada Largus, Vesta and XRAY): transmission oil “TRANSELF TRJ (NFJ) 75W-80” SAE 75W-80 API GL-4+.
• Gearbox JH5 (Lada Largus, Vesta and XRAY): oil TRANSELF TRT 75W-80 TPM4501/B06138A.

Selecting the viscosity of the transmission oil:

What kind of oil is in the automatic transmission of Lada Granta and Kalina 2? Genuine EJ-1 ATF gear oil (supplied by JX Nippon Oil and Energy Corporation).

Which gear oil composition should I choose ? To answer this question, we conducted surveys among owners of Lada Grant, Lada Kalina and Lada Priora, asking them to answer the question “What composition of transmission oil do you use in your car” and as a result we received approximately the same results:

Which brand of gearbox oil should I choose?

The next polls and very similar results:

What should you pay attention to?

The gears in the VAZ 2115 gearbox work equally well in both synthetic and mineral lubricants. Here it would be advisable to be guided by economic considerations and use mineral oil, which is much cheaper.

The main criteria that apply to it can be called:

• Relative sliding speed provided by oil.

It will be important to pay attention not only to the kinetic viscosity of the oil, but also to the additives contained in its composition. They are different, but for a VAZ gearbox it is important to choose a lubricant in which sulfur compounds will predominate. Thanks to them, you don’t have to worry about the formation of “scoring”, since the additive changes the chemical structure on the surface of metal parts. And the film covering them prevents the surfaces from quickly deteriorating.

Lubricant viscosity

It is necessary to pay attention to the kinetic viscosity of transmission oil first of all. You can select a suitable lubricant by knowing the climatic characteristics of your region; if you live in a region where the temperature often drops significantly below zero, then you should purchase class 90 oil, which is quite reasonable for most regions of Russia. In hotter climates, SAE grade 140 lubricant is suitable. Based on these principles, you must decide for yourself which oil is best to fill into the VAZ 2115 box in your region.

A domestic manufacturer has released a special gear oil for the VAZ 2115 gearbox called Reksol T; it meets the parameters 0W-85 API GL-4. Then another brand, Lukoil, released an analogue with the same parameters.

The last digit in the numerical designation indicates the temperature range permissible when using a particular lubricant. The higher the number, the hotter the climate in which it is recommended to be used.

For reliable operation of the VAZ 2115 gearbox, the manufacturer recommends a scheduled replacement of lubricants after every 60 thousand km. To eliminate the possibility of accidental failure of the gearbox, the car owner should adhere to the following rules:

Sometimes it makes sense to purchase lubricant on tap from a barrel, but this can only be done if you are completely confident in the quality of the product being sold. Beware of fakes!

What is the difference between GL-4 and GL-5 75W-90 oils?

As already mentioned just above, the purpose of TM GL-4 (according to GOST 17479.2–85) is for operation in transmissions with bevel and hypoid gears , operating at contact stresses up to 3000 MPa and oil temperatures up to 150 °C. By and large, these are gearboxes of front-wheel drive cars. API GL-5 - ensures reliable operation of hypoid gears operating with shock loads at stresses above 3000 MPa. It is used in gearboxes with hypoid bevel gears and for final drives with cardan drives in drive axles (with limited slip differential LSD). This transmission fluid provides better protection under high load and pressure conditions.

Errors when choosing TM 75W90 and the difference between GL 4 and GL 5.

The key feature is that 75W90 API GL-4 oils contain two times less sulfur-phosphorus additives than similar ones, only of a higher class. Such additives create a special protective coating on parts that prevents wear, but this substance is even stronger than the surface of parts made of copper or other soft alloys. Therefore, using TMs for purposes other than their intended purpose threatens to wear out the surface of an element made of soft metal. So, in those gearboxes where it is necessary to use 75W90 GL-4, and GL-5 is poured, there is a rapid appearance of copper shavings, since the synchronizers are made of copper, and the sulfur-phosphorus additive kills them.

Step-by-step instruction

• Warm up the car, it is better to do this on a lift, but if there is none, then you need to drive the car for about 10 km, while switching all gears;
• Raise the right front part of the car using a jack;

Important to remember! Be sure to play it safe and place a safety bar under the car, which will save your life if the jack becomes warped or weakened.

They carried out a real revolution in the automobile market - streamlined shapes, a comfortable interior, significantly improved gearboxes and internal combustion engines; for the Russian market at the time of its release, the “ten” became a real sensation. But the improved gearbox also created a completely understandable question - how to change the oil in a VAZ-2110 gearbox, if no one has ever encountered anything like this?

When choosing oil for the VAZ-2110 gearbox, you should take into account the operating conditions of the vehicle.

When to replace?

Referring to the plant regulations, check the level and condition of the oil every 15 thousand kilometers, take 0 km as the reference point, replace it every 40 - 70 thousand km, based on the properties and composition of the oil. Factory regulations vary greatly in the testing range due to the typology of oils that motorists can use. Let's make it a little clear - there are 3 types of transmission oils suitable for VAZ-2110 cars:

1. Synthetic – high purification and filtration of all components of the product; a large number of additives are added to the composition, which protect the gearbox from wear, internal damage and corrosion. The replacement interval greatly depends on the viscosity and quality, the standard is 65 – 70 thousand km.
2. Semi-synthetic - has the required percentage of additives aimed at protecting gears and partially for other gearbox elements. The recommended replacement interval is 45 – 55 thousand km. Due to its composition, it strongly competes in cost with synthetics, approximately 1.5 - 2.5 times cheaper.
3. Mineral – natural, . Requires constant monitoring of the condition of the car, quickly loses its existing properties and becomes unusable. Service life - 20 - 40 thousand km, replacement is desirable no later than after 30 thousand km.

On VAZ 2110 - 2112 cars, a two-shaft 5-speed gearbox is used, combined with a differential and final drive. On the drive (primary) shaft there is a gear block that is in constant contact (engagement) with the driven gear block. The driven shaft with a removable gear and three synchronizers, just like on the drive shaft, is responsible for gears from 1st to 5th. The rear-wheel drive (R gear) is located in a separate unit.

The oil volume in the box is standard for the entire family - 3.3 liters, but, according to experts and car enthusiasts, the ideal oil volume in the VAZ-2110 gearbox remains 3.5 liters (about 1.5 - 2 mm above the maximum level ). It is believed that a slight excess compensates for the wear of the 5th gear, the gears of which are located higher than all the others and do not receive enough lubrication during operation.

The best choice for domestic classics

Mechanical gearboxes, which are installed on domestic cars, have several irrefutable advantages. Firstly, this is an extremely reliable unit that does not require expensive maintenance. Even if there is a need for major repairs, it will be relatively inexpensive.

However, regular maintenance should not be neglected. It is advisable to purchase lubricant from trusted places and not skimp. The replacement interval is 3-4 years or 150 thousand kilometers, whichever comes first. This is not motor oil that needs to be changed every 8-10 thousand miles. An excellent choice would be Castrol or Motul. From budget and high-quality, I can recommend.

Transmission fluid selection

Given the wide range of climates in Russia, car portals often conduct surveys about what kind of oil car owners pour into the VAZ-2110 box. Based on the survey results, it can be argued that more than 70% of motorists have chosen semi-synthetics. The rationale for the choice is quite simple - harsh climate and frequent use of the car expose the gearbox to serious wear, which prompts frequent oil changes (50 - 60 thousand km) to maintain the working condition of the car.

Which manufacturer is better to choose?

Opinions about transmission manufacturers differ greatly; some support domestic manufacturers, while others, on the contrary, rely on the recommendations of well-known car factories. Which gear oil is better, and which one you choose, depends only on your personal point of view and the ability to evaluate and listen to the advice of experts. According to leading car factories such as Mercedes-Benz and BMW, they are:

• Liqui Moly;
• Mobil.

The AvtoVAZ fan club supports both a selection of reputable brands and Russian manufacturers, for example, Rosneftekhim, Lukoil, Rosneft. In any case, the choice of high-quality gear oil for the VAZ-2110 gearbox occurs through a long selection process, where each car owner goes through a long journey of testing and experimentation.

What is best for the Priora checkpoint?

Approximately 90% of owners of this sedan prefer to pour exactly what the manufacturer recommends. The whole point is that Priora is advised to fill it with Lukoil TM-412. This is a relatively inexpensive, but at the same time high-quality lubricant, which is available in all car dealerships. However, there are many other suitable gear oils. For example, Rosneft, Castrol, Motul, etc. are often used. The last two options are the most preferable. True, their cost is much higher than their domestic counterparts.

It is better not to use mineral-based oils. This lubricant oxidizes much faster and therefore requires more frequent replacement. In addition, there will be uneven wear of the rubbing parts, which will ultimately lead to physical vibrations and deterioration of the operation of the unit as a whole. Therefore, it is advisable to fill in high-quality synthetic all-season gear oil. If you observe the intervals and do not overload the gearbox, then it will work for a long time and properly. Which gear oil is best for Priora? Usually, high-quality TM-412 lubricant is sufficient, but more expensive analogues can also be used.

How much oil should be poured into the gearbox?

The standard volume, according to the regulations, is considered to be a volume of 3.3 liters. 3.3 liters is the transmission level between the “MIN” and “MAX” values ​​on the dipstick, but more experienced car owners and experts advise pouring 3.5 liters into the gearbox due to the higher location of the 5th gear in the box. A level of less than 3.3 liters is unacceptable, since the risk of wear of the 5th gear tends to 80% at the time of topping up or replacing. How many liters are in the box of your VAZ-2110 car needs to be monitored approximately every 10 - 15 thousand kilometers, that is, approximately every 1/3 of the mileage after replacement.

Necessary tool

"VAZ-2110" has a somewhat non-standard arrangement of the box, this applies to both the injector and the carburetor. If the drain hole is located at the bottom of the box and access to it is easier from an inspection hole or a lift, then it will not be possible to simply get to the filler plug or neck. To replace you will need:

• socket wrench 17;
• dry clean cloth;
• hard thin wire;
• empty container with a volume of 4 - 5 liters;
• oil syringe or funnel;
• long soft hose (25 – 30 cm);
• 4 – 5 liters of fresh oil.

Before starting the replacement, warm up the car and drive for 5 - 7 kilometers so that the transmission in the gearbox warms up and becomes less viscous.

How to check the level and add oil

Constant level monitoring has been and remains an integral part of car care. The VAZ-2110 family in its initial production was produced without a control probe, which seriously complicated the on-site control process. If your car is not equipped with a dipstick, then the technology for checking the oil level will look like this:

1. Drive the car onto an overpass, inspection hole or lift.
2. Unscrew the control plug with a key to 17.
3. The normal level corresponds to a slight dripping of oil from the control plug.
4. If there are no leaks, top up using an oil syringe.
5. Tighten the inspection plug tightly.

Control with a probe is carried out in a matter of seconds:

1. Unscrew the dipstick from the gearbox (located next to the thermostat and starter).
2. Wipe the dipstick with a dry, clean cloth.
3. Insert it back and after 10 - 15 seconds remove it again.
4. The amount of oil on the dipstick should tend to about or be slightly higher.
5. Screw the dipstick into place.

Topping up oil

Before starting the operation, be sure to check the level using a check plug or dipstick, and also remember what kind of oil is currently poured into the gearbox. Adding other oil is strictly prohibited, both in terms of viscosity and production. Strictly the same brand and the same viscosity. For topping up, an oil syringe or funnel is used, at the ends of which a flexible long hose is placed, and the connection point is firmly fixed with electrical tape. Perhaps every car owner should know how to avoid overflowing; if you are doing this for the first time, we advise you to pour it in stages, in small quantities, checking the level step by step.

Step by step replacement

Novice car owners often ask on forums and in comments about how the VAZ-2110 is produced, especially if the car was purchased recently or there were problems with the gearbox.

Draining the transmission

Correct and complete draining occurs only after a short trip, when the lubricating fluid has not yet completely warmed up, but has lost its viscosity. Follow step by step:

1. Place the car on a lift and turn it off.
2. Remove the breather plug and clean them.
3. Raise the car.
4. Prepare an empty container.
5. Carefully unscrew the drain plug.
6. The oil will drain completely in 10 - 15 minutes.
7. Screw the plug into place.

If chips or foreign small objects are found in the drained liquid, it is recommended to wash the box with a special compound that can be purchased at the store.

Flushing the gearbox

Washing the VAZ-2110 gearbox is carried out in order to completely clean the box from foreign objects in the form of chips, dirt and other small particles. First purchase flushing fluid from a car dealership and perform all the steps sequentially:

1. Raise the front wheels of the vehicle onto a stable platform.
2. Pour in 1 liter of rinse and tighten the filler cap.
3. Start the engine.
4. Engage the first gear and wait in this mode for 10 - 15 minutes.
5. Turn off the engine.
6. Drain the flushing liquid (5 - 10 minutes until completely clean).
7. Add fresh oil.

Flushing must be carried out once every 3-4 complete replacements of the transmission, since a large amount of dirt accumulates in the gearbox housing, which negatively affects the properties of even the most expensive and high-quality oil.

Fill with fresh transmission oil

Changing transmission fluid is a simple process unless you are doing it for the first time. When the car has been completely prepared for filling, and the necessary parts have been cleaned and tightened, prepare fresh oil, an oil syringe or funnel and follow the instructions:

1. Insert a funnel into the filler neck.
2. Pour in the required amount of liquid (preferably 3.5 liters).
3. Wait 10 - 15 minutes, allowing the oil to drain.
4. Check the level with a dipstick.

If the gearbox does not have a filler neck, use an oil syringe, extending its end with a flexible hose:

1. Insert a hose with a syringe into the filler hole.
2. Gradually add oil.
3. The control level is the bottom of the filler hole.
4. Screw the plug tightly.

Don't forget to give the oil a chance to drain and disperse to all parts of the gearbox. The process is completely completed and the car is ready to go.

What volume of oil do you usually fill, more than the “MAX” level or do you stick to the golden mean? Share your opinion in the comments and justify your point of view, giving novice car owners food for thought.

Tell me, please, because there are different opinions among sales assistants in stores and among my acquaintances who are car enthusiasts. Question: “Which oil is better to pour into the gearbox of a VAZ 2110 (in my case, 21102) - mineral, semi-synthetic or synthetic” The fact is that there are opinions that synthetics corrode our, domestic, oil seals. Please tell me your opinions or based on experience. I want to replace butter. Just for the first time.

Doesn't corrode but seeps into the cracks

I have a slightly different approach, probably outdated. Refers to gearbox oil. Liquid for the city, thick for the highway. It's 21103, I don't know what it was filled in there at the factory.

Dog Le-a-zu

Only GL-4 groups in front-wheel drive, and the viscosity is of course the best 75W90, this is synthetic 250-350 rubles per liter. It is liquid in winter, and when heated it maintains a stable viscosity.

Castrol TAF-X,GL-4. Synthetic, excellent oil. The leaking seals are complete nonsense. It has been flooded for five years and is not leaking anywhere. Excellent operation of the gearbox even in very severe frosts, gears shift smoothly, without jamming. Long service life, I will change it no earlier than 100-120 t.km. What else is needed? I immediately drained what was filled in at the factory.

About oil seal leaks, BULLSHIT. and most sellers don’t know anything at all. Pour expensive synthetics everywhere and you will be happy -)

Yes, I don’t know, they wrote about expensive synthetics while driving, like it’s intended for other gearboxes, they say the enemies have different standards. In short, they gave 1st place to Lukoil, then it seems to be Castrol, but the question is whether to believe their tests or not. Someone changed the clutch for me (VAZ 2112) and advised me to change the gearbox oil, and advised Lukoil... look, there are 4 and 5, you need 4 in no case, don’t mix it up!!!

“I apologize in advance, I just don’t want to create a topic,” but on a VAZ 2104 what is the best oil to pour into the gearbox, just be more specific please, otherwise I’ve never changed it

If I remember the manual for 9 correctly, you need to pour engine oil there.

You can, of course, take a classic box and axle 80w90 into an axle HD 80w90 into a GX 80w90 box and take a higher viscosity 85w140, but in winter you won’t be able to turn the frozen “casinak” by any force.

in fact, for hypoid gears, which are gearboxes, the GL-5 group was created

The vast majority of boxes do not have a hypoid main pair. Conventional helical gearing. Therefore, GL-4 is the best. Life tests of GL-5 in VAZ front-wheel drive gearboxes did not show increased wear of synchronizers. Motor oil was poured into the gearbox back in those shaggy years when there was nothing else. Now doing this is a perversion of the unit.

Infantile Elephant

Any unit with rotating parts requires lubrication. And in the case of a variable gearbox, the lubricant must also be of proper quality. Which oil is better to buy for the transmission of a VAZ 2109? Light on this issue is shed by these instructions for choosing oil for a VAZ 2109 gearbox. Study this article carefully - here you can learn about the choice between engine and transmission oil, synthetic and semi-synthetic, as well as the choice between different manufacturers of transmission oils. Photos and videos will help you understand this difficult issue more thoroughly. So, let's begin.

• Oil options for VAZ 2109 gearbox
• Engine oil
• Transmission oil
• Manufacturer's choice
  Domestic manufacturers
• Foreign manufacturers
• Some tips for filling oil
• Conclusion

Oil options for VAZ 2109 gearbox

Oil requires careful selection. So what are the options - what to choose from? So:

• When front-wheel drive cars appeared, owners tried two options. The first was the same as for the “classics”, that is, transmission oil TAD-17, but experience has shown that such oil is not suitable for the nine. And all because the main pair in the nine gearbox is helical, and not hypoid, as on the classic.
• The second option is regular motor oil. That's where we stopped at that time. This option will be discussed in more detail later.
• Now there are many other options for oil for filling in the VAZ 2109 gearbox.
  Domestic oils
• Foreign oils
• Various classifications (GL-4, GL-5 and TM-4, TM-5)
• Various viscosities (SAE 80, SAE 90)
• Mineral, semi- and synthetic oils

Advice! As you can see, the choice is large, and the correct choice is usually one or two. Take your time, but carefully study the theory before you start changing the VAZ 2109 oil.

Let's sum it up

So we figured out what kind of oil to fill in different car models. Currently, the choice of gear oils is simply huge. Therefore, you can find a suitable option for both the Niva and the VAZ-2114. What gear oil is best to fill? Definitely original. The fact is that today fakes are quite common. Therefore, you should buy only in trusted places, preferably from a dealer. But this applies to foreign oils. Domestic ones are counterfeited very rarely, due to their low cost.

The choice of oil for each car is different

This applies not only to different car brands. Even for different VAZ 2109 vehicles, completely different transmission oil options may be suitable. Let's figure out which oil is best to use in which case.

Engine oil

So:

• What are the benefits of using motor oil in transmissions? The first thing that comes to mind is its price, which is within acceptable limits.
• Analyzing reviews from owners of 2109, you can notice some features. For example, there are a number of cases when a car drove 300-400 thousand kilometers on motor oil poured into the gearbox without the slightest claim for repairs.
• On the other hand, other cases show that the use of engine oil is undesirable, since it leads to rapid wear of gearbox parts, such as synchronizers or gears.
• So how can you determine whether the engine oil is suitable for the gearbox of a VAZ 2109? Again, analyzing the overall picture of the use of such oil, we draw a simple and very important conclusion.

Conclusion! Engine oil can only be filled in if the vehicle is manufactured before 1993-1995. For cars produced in later years, the use of engine oil in the transmission is highly discouraged.

Transmission oil

There are a great variety of such oils and there is not enough time and patience to consider all specific oils. Therefore, we will consider only categories of oils, and in some cases we will give examples. Go:

• Let us mention the TAD-17 in a little more detail. If anyone doubts that it cannot be used in the VAZ 2109, read below the reasons for this.

• The viscosity or thickness of TAD-17 oil is very high, which leads to the following problems: the car will not start in winter; extreme pressure additives (which in themselves give a good effect) are contained in very large quantities in the oil.
• A large amount of extreme pressure additives contributes to intensive wear of synchronizers.
• Synthetic oil, it would seem, should be better than others. It is better in thickness, has positive qualities, and has additives. But there is one thing! The use of synthetic gear oil (designated GL-5 or TM-5) is encouraged in sports gearboxes, where the quality of the parts is better, the temperature is higher, and (in some cases) there are no synchronizers.

By the way! By carefully reading the instructions for the transmission oil, you can determine whether it is suitable for your car or not.

• So, in the instructions for GL-5 class synthetic oil it is directly written: “used for unsynchronized manual transmissions.”
• And one more point not in favor of synthetics is its price. The cost of such oil is high, and practicality is not very good - therefore, the use of synthetic oil in VAZ 2109 gearboxes does not make sense.
• And the last option is semi-synthetic gear oil. It is perfectly suited for use in this car.
• The designation of this oil is GL-4.

By the way! The service book for the car indicates the type of oil recommended by the manufacturer. This is exactly GL-4 or TM-4.

• In terms of density, it is better to take the designation 75 or 85. The composition of this oil and its properties are optimal for both gearbox gears and its synchronizers.
• As for the winter period, semi-synthetics will not freeze as much as mineral water, for example. In frosty weather of -25 degrees the car will start, just like in summer.

Reviews from motorists

It is also necessary to pay attention to the opinions of experienced drivers. The fact is that sometimes it is not advisable to buy expensive gear oils, because some domestic ones have no worse performance characteristics. For example, many people ask the question: “Which transmission oil is best for the VAZ-2106?” The manufacturer recommends filling with Rexol T Hypoid or Lukoil TM-5. But motorists do not always pour these exact oils.

This is especially true for drivers who love and care for their cars. In this case, very often preference is given to more expensive foreign analogues, such as Castrol or Shell. Liquid Moly is very popular. Two liters of lubricant costs about 1,000 rubles. It may seem expensive to many, but it's worth it. This is a synthetic transmission that is simply perfect for domestic gearboxes.

Manufacturer's choice

We have already listed the brief characteristics, and now you can delve into the choice of oil manufacturer for the Samara gearbox. So, who does the best on the VAZ 2109?

Domestic manufacturers

So:

• The gearbox oil declared by the plant is TM-4-12. Ideally, you should use it, of course. This oil was specially developed for the gearbox of this particular vehicle.
• Using logic, we come to the conclusion that since it was specially developed, it must be the best. The manufacturer may be different - for example, Rexol.
• For example, the M6z12G1 engine oil used in the VAZ 2109 gearbox falls slightly short of the TM indicators.
• LukOil SAE 15W-40 is also a good competitor to specially developed oil, TM-4-12. The gap from it is only 4%.

Foreign manufacturers

We analyze the oil for the foreign-made VAZ 2109 gearbox:

• The Castrol brand, and more specifically EP-80 and EP-90 oil, which according to the GL-4 class is undesirable for use in Samara gearboxes. Its properties are more suitable for sports gearboxes.
• But the foreign company Valvoline, which produced DuraBlend SAE 75W-90 oil, distinguished itself with good performance for our car. This semi-synthetic oil is in second place, after the recommended domestic oil TM-4-12.
• On the other hand, the same Valvoline, but no longer GL-4, and GL-4/5 is not suitable for high-quality operation of the VAZ 2109 gearbox.

We remember that the presence of extreme pressure additives has a positive effect on the overall performance of the gearbox. However, too much of them contributes to rapid corrosion of metals. This is because extreme pressure additives include sulfur, which corrodes gears.

• From this point of view, motor oils are the best contenders (but we also remember about their other qualities).
• And again, semi-synthetic Valvoline turns out to be close to the standard - TM-4-12. But synthetic, on the contrary, turns out to be the most destructive in this regard.

As for other manufacturers, it is worth paying attention to some points and studying the composition of the oil in detail. Pay attention to:

• Viscosity
• Oil operating temperature – pour point
• Number of additives and their type

The vehicle transmission, like the power plant, cannot be operated without lubrication. Not only the performance of parts and their normal functioning, but also the overhaul life of the products depends on its quality composition. An effective means of maintaining a vehicle in good condition is to periodically monitor the level of lubricant in the gearbox and replace it as necessary.

How to correctly determine which oil should be poured into a VAZ 2110 transmission type box in order to operate the “ten” for a long time and successfully?

Rating of the best gear oils with viscosity 75W90

To build a rating of the best oils, you need to navigate among the following indicators:

• Viscosity _ The oil must maintain optimal viscosity both at low temperatures and maintain its astringent properties at high temperatures;
• Temperature characteristics . Each liquid has its own pour point and ignition temperature, TM should have the largest gap between these indicators;
• Critical load . The higher this number, the better the product;
• Bully index . Unfortunately, there are no standards for this index, but the higher this value, the better the TM;
• Welding load . According to GOST, this value should be no lower than 3,000 H;
• Wear indicator . This criterion is determined only for GL-5 class oil; it should be less than 0.4 mm.

The TOP of the best transmission oils does not take into account their cost, but is given based on reviews and comparative tests.

In many respects, Motul Gear 300 75W90 transmission oil takes first place among all tested. This transmission has the highest protection against scuffing (the index is 60.1), welding, oil film stability without loss of engine power, and an average wear rate (0.75 mm). Although it cannot boast of viscosity characteristics (especially at sub-zero temperatures).

Temperature test of transmission oils 75W90

Second and third places are occupied by transmission fluids from Castrol (Syntrans) and Mobil (Mobilube). Castrol Syntrans Transaxle oil is used in gearboxes, transfer cases and drive axles. It has good low-temperature fluidity, but compared to Mobile, the scuff index is quite high for a liquid of this class, but the wear level is even better than Motul (59.4).

TM Mobil Mobilube can be placed in third place, since it has good test results for the level of protection and wear under high loads, and therefore provides low friction losses at operating temperatures. But, unfortunately, it has an insufficient viscosity index at sub-zero temperatures.

The fourth result when testing transmission oil was shown by Total Transmission SYN FE 75W-90 oil. Reviews about this fluid are also good, although since it is universal - it has API GL-4/GL-5, it will not be suitable for all gearboxes. This TM has a scuff level of 58.8, which is even better than the leader in the rating of gear oils 75W90. But it cannot boast of wear levels and good viscosity in low-temperature tests.

Semi-synthetic gear oil LIQUI MOLY Hypoid-Getriebeoil TDL 75W-90 GL-4/5 also performs well in tests, especially standing out when tested at minus 40; its fluidity at such a low temperature will allow the gearbox and gearboxes to operate without problems. However, other important indicators are at an average level.

synthetic oil ZIC GF TOP 75W-90 in this rating, since there is very little data on its wear and scuffing indicators, although the temperature test passes excellently. This gear oil can be used in manual transmissions (including synchronized transmissions) and drive axles. According to reviews from car owners, it significantly reduces transmission noise, withstands extreme loads and has virtually no drawbacks.

It is also impossible not to pay attention to Transyn 75W-90 API GL 3/4/5 oil from the manufacturer Eurol, since, despite the lack of real temperature tests and a very high level of wear - 0.94, it has a good scuff level - 58.5 and is very popular among car enthusiasts.

As you can see, the range of 75W90 gear oils on the market is quite large and there is always something to choose for your needs and affordable price. But remember that you need to select not because your neighbor advised, but based on the needs of your car’s transmission and the characteristics of the transmission fluid itself.

There are often thematic forums on the Internet where disputes between motorists regarding the choice of engine oil do not subside. Some people only pour what is approved by the manufacturer, while other drivers do not adhere to such strict limits. A completely similar situation has arisen around the question of which gear oil is best for a particular car model. We will try to understand this issue in this article.

A few words about gear oils

Such materials are used in manual and automatic transmissions, transfer cases, differentials and steering systems. In these units, the torque is transmitted by pairs of gears of the gear type. Any elements of such a system in mechanical devices are lubricated by being in oil, or by supplying it to the working elements.

Oils of this type are replaced every 60-70 thousand km. Periodic changes of such fuels and lubricants have a beneficial effect on the performance properties of the vehicle.

Transmission oil in the VAZ 2110 gearbox has the following functionality:

1. Protects the working surfaces of parts from the effects of increased friction, thereby reducing losses due to excessive metal-to-metal resistance.
2. Control over the correct operation of contacting working surfaces using thermal lubrication functions.
3. Protects transmission elements from impact loads, protects the car from excessive vibration and various noises.
4. It has a protective effect on gearbox elements from corrosion and removes wear products from stress zones.

In a VAZ 2110 car, the oil in the gearbox must maintain an initially high degree of viscosity at operating temperatures from 80 to 120°C and further up to 200°C. This is due to an increase in temperature conditions at the points of interaction of gear drives. On the other hand, the excessive viscosity of such lubricants at subzero temperatures will interfere with the normal movement of the gear transmission.

Requirements for gear oils:

• ability to counteract oxidative processes;
• excellent anti-wear qualities;
• good ability to resist corrosion;
• counteraction to foaming processes.

The characteristics of transmission oils in terms of viscosity and temperature are determined according to the international SAE classifier and are divided into 4 winter (with the letter W) and 3 summer types.

Transmission oils in automatic transmissions have slightly different functions, because in hydromechanical systems, like an automatic transmission, the oil serves as the working fluid. Such lubricants, taking into account the above requirements, must have an anti-friction effect.

In addition, the requirements for the viscosity of fuels and lubricants are increasing, because the automatic transmission contains a large number of components and parts that perform a wide range of functions: a torque converter, automatic transmission gears, a control complex where friction pairs made of various materials work: steel, cermets, bronze, etc.

In addition, such units are subject to aeration due to high-speed oil flows, which is a prerequisite for the appearance of foam. This is fraught with accelerated oxidation and corrosion of automatic transmission materials.

Viscosity characteristics 75w and 90

According to SAE, TMs are divided into types and, accordingly, their purpose depending on viscosity. Since we will be talking about 75W-90 gear oil, we will first of all look at its characteristics.

75W – this indicator is known as “winter”, it shows the degree of fluidity at low temperatures. The lower the value in front of the letter “w”, the more fluid the transmission is in the cold. For this type of oil, the threshold should be at -40 °C.

The second indicator of the viscosity range is 90 , also called “summer”, indicating the maximum tolerated positive outdoor temperature at a temperature of 100 degrees Celsius. The parameter itself also does not reflect the true value, you just need to know that according to reference data, this threshold will be up to +35 °C.

It would seem that why 75W90 oil is the most suitable for our latitudes , why not create a universal one with an even wider temperature spectrum? But it's not that simple. Protection against friction between gear surfaces directly depends on the lubricity of the gear oil. Although this indicator significantly improves with increasing viscosity, the law of resistance comes into force, and transmission power losses increase due to the waste of energy squeezing it out from under the gear teeth. Also, viscous oil thickens very much in the cold. Less viscous, it feels good at sub-zero temperatures, but has a less durable protective film and worse lubricating properties. To balance these two indicators, special additive packages are also used.

Transmission fluid must perform the following functions:

• exclude friction, jamming, scuffing, pitting (deep metal corrosion) and other damage;
• reduce energy loss and increase efficiency;
• remove heat from friction surfaces;
• reduce noise and vibration during gear operation.

Therefore, TM 75W90 from different manufacturers, of course, is somewhat different in its properties and, naturally, in its price tag. In addition, 75W90 gear oil is often synthetic, although in some cases, a number of manufacturers may indicate it on the label as semi-synthetic. But in fact, it differs from synthetics only in the content of synthetic substances of 20% - 40% and the amount of additive from 2 to 15%.

In addition to the fact that these fluids are classified according to the SAE system, there is a division of transmission oils according to the API system with the index “GL” (in the Russian version - the index “TM”).

Changing the oil in “mechanics” “tens”

Procedure for changing oil in manual transmission:

1. It is better to replace the lubricant immediately after operating the vehicle, when all units maintain operating temperature conditions.
2. We place the car on a level area, set the parking brake and turn off the power to the vehicle.
3. For convenience, we place the “front” of the car on a stand. Check the oil level with the vehicle standing horizontally.
4. Clean the filler plug and inspection hole.
5. Place an oil drain tank under the gearbox housing and unscrew the plug. Take measures to prevent burns from hot aggregate oil.
6. After draining the waste, thoroughly clean the hole plugs, paying special attention to removing metal particles from the inserts with magnets.
7. Wait until the oil has completely drained and place the car in a horizontal position.
8. Fill the unit with oil and test the lubrication level in the unit. Tighten the inspection plug, take a short trip and check the oil level in the gearbox, and if necessary, add the missing amount. Tighten the plug with the recommended torque.

Changing the oil in an automatic VAZ 2110

Filling the VAZ 2110 automatic transmission with oil is required every 30,000 km. after the next replacement. In this case, it is also possible to change the lubricant earlier if there is extraneous noise and crunching in the automatic transmission.

According to the recommendation of the car manufacturer, it is recommended to fill this model with GL-4 oil according to API tariff. Thus, shell oil 75W90 is one of these recommendations from the manufacturer. It is better to carry out the procedure at a service station, where professional specialists will quickly and efficiently carry out all the work.

Classification of oils

According to the international API system, gear oils are divided into several categories:

1. GL-1 - SAE 75W. These oils are suitable for spur, worm, and bevel gears operating at pressures up to 1600 MPa and temperatures not exceeding 90 degrees.
2. GL-2 - SAE 80W/85W. Suitable for spur and spiral bevel gears. They operate at pressures up to 2100 MPa and temperatures up to 120 degrees.
3. GL-3 - SAE 90 - similar to the previous one, but withstands up to 2500 MPa and up to 120 degrees.
4. GL-4 – SAE 140. Designed for various transmissions, including hypoid ones with operating pressures up to 3000 MPa and temperatures up to 150 degrees.
5. GL-5 – SAE 250. Designed for hypoid gears with pressures over 3000 MPa and temperatures over 180 degrees.
6. GL-6 – applicable with hypoid gears operating in harsh operating conditions. The oil contains particularly effective anti-wear and extreme pressure additives.

Oil designed for VAZ oil is suitable for front-wheel drive vehicles. Typically, lubricants of classes GL-3 or GL-4 are poured into such boxes.

Transmission seals

VAZ 2110 gearbox seals are replaceable components in the transmission of this car. There are the following types of repair work when maintaining the gearbox for a VAZ 2110 car:

• replacement of gearbox seals located on front wheel drives;
• replacing the gearbox seal on the unit’s input shaft;
• Replacing the cuff of the speed selection system rod.

All this work is best carried out under the supervision of an experienced assembly fitter, who can help with practical advice if necessary.
