Priora average consumption increases at idle speed


Of course, Russia, over its more than thousand-year history, has enough examples for well-deserved pride. However, the auto industry is clearly not one of them.

Lada Priora is considered one of the most controversial achievements of the automotive industry of the Russian Federation. On the one hand, it was well received both by customers, as evidenced by excellent sales at the time of release, and by representatives of the automotive press. On the other hand, the joy of the owners knew no bounds only because of the relatively low cost of this vehicle. As soon as all its shortcomings, characteristic of most cars from the Togliatti company AvtoVAZ, were revealed, Priora began to be hurled with choice curses.

On-board computer sound settings

Vesta’s on-board computer, as we already wrote at the beginning of the article, has many interesting functions that can surprise even owners of more expensive car brands. For example, the sound menu - it allows you to turn on/off the sounds of turn signals, warning sounds about the need to change gears and other sounds.

If you simultaneously press and hold both buttons on the end of the right switch, you will be taken to the menu for adjusting the volume of various sounds. When you add the volume of the turn signal, a squeak is added to the main sound of the relay, which, along with the setting, also changes the frequency (louder - lower frequency).

A long-awaited feature was also the ability to change the sound heard when the seat belt is not fastened. In addition, you can adjust the sounds of the parking sensor.

In fact, all the functions of BC Vesta have not yet been fully studied, and every time something new is discovered, which undoubtedly pleases car owners.

Lada Priora 1.8 MT

Information from the manufacturer

In 2021, sales of the Lada Priora car begin, the manufacturer of which is. The new version is equipped with an engine with a displacement of 1.8 liters and a power of 123 horsepower.

Acceleration time from zero to hundreds has increased significantly compared to previous models - it is now 10.0 seconds. The maximum speed to which the updated Priora can be accelerated is 190 km/h. The consumption in this case is 9.

8 liters in the city cycle and 5.4 liters on the highway.

The situation with real gasoline consumption

  • Mikhail, Peter. Lada (VAZ) Priora 1.8 MT 2021. Overall, I’m happy with the car. For such little money I got the equipment I wanted. In terms of breakdowns, I haven’t encountered any yet. Consumption remains on average at 7.5 liters. I would like, of course, better sound insulation. Yes, and the seats could be replaced, since the standard ones are not of the best quality.
  • Sergey, Suzdal. The car, although produced in 2021, has a lot of shortcomings. After the first 10,000 km, the suspension and generator had to be changed. I also redid the sound insulation, or rather, installed it, since there is almost none in the Priora. The only good thing about it is the engine. Its consumption is economical. On the highway at 90 km/h it consumes 5.5 liters. In the city, no more than 9.5 liters are spent.
  • Andrey, Moscow. Priora is a good car. Price-quality-equipment correspond to each other. The engine is good and grippy. At the same time, its consumption is economical, on average 7.2-7.5 liters per 100 km. Of course, I consider these strange creaks in the cabin to be a big minus. Apparently the noise here is of poorer quality. Plus the quality of the paint is poor - there are too many chips.
  • Vladimir, Sevastopol. Lada (VAZ) Priora 1.8 MT 2021. The overall impression of the purchase is the worst. I don't think she has any advantages. A year after the purchase, my body began to rot in several places. As for the interior, the trunk opening button should be recessed so that it does not open while driving by pure accident. The engine is noisy, eats a lot - 9-10 liters.
  • Nikolay, Izhevsk. Of everything in the Priora, the only normal thing is the 1.8 liter engine. Powerful and economical. Consumption is a stable 10 liters in the city, 6 liters on the highway. Everything else: sound insulation, painting, interior assembly, seats - as always in our automotive production, at the lowest level.

In 2021, it was decided to stop production of the Lada Priora, but soon they decided to postpone the production stop to 2020. So, in 2021 a new version of the Lada Priora will appear. In terms of significant modifications, we can highlight the modified design of the car.

This mainly affected the front of the car. As for the power units, the same 1.6-liter ones with eight and sixteen valves remain.

Also, in addition to the 5-speed manual, the new Priora will be equipped with a robotic automatic transmission.

Video on the topic “Lada Priora (2020). increased fuel consumption"

What affects consumption or why the car consumes gasoline.
From the experience of my TAZ Kalina VAZ, the result of cleaning the mass air flow sensor and throttle body using spark plugs

We measure the consumption on Priora part 3

Theoretical indicators

The factory specifications of the Priora indicate the fuel consumption of this car. But the data is averaged and does not reflect the full picture. The manufacturer claims that this 16-valve machine with a power of 98 horsepower and a manual transmission “eats” 6.9 liters per hundred kilometers.

And at the same time, the flagship model, which drives an automatic transmission with five gears, consumes 6.6 liters per 100 km with 106 horsepower. But a variation of a car without an automatic transmission with 106 horsepower “eats” 6.8 liters, covering the same distance. All calculations of Lada Priora costs per 100 km are made under mixed mode conditions.

The table shows the consumption of a 16-valve Lada Priora with a 1.6-liter gas tank while traveling along a highway or a busy city.

Mode98 l. With. with MT 106 l. With. with 5AT 106 l. With. with MT
Highway (outside the city) 90 km per hour5.5 liters per hundred kilometers5.5 l per 100 km5.6 liters per 100 km
Around town9.1 l/100 km8.5 liters/100 km8.9 liters/100 km
Mixed6.9 l. per 100 km 6.6 l liters/100 km6.8 l/100 km

Based on the indicators, we can conclude that the highway is the most economical mode. Gasoline consumption on the Priora, regardless of power and gearbox, is noticeably lower.

The 8-valve Priora 1.6 MT produces 90 horsepower on a 100-kilometer country road using 6.2 liters. While it will travel the same amount on city streets, it will already consume 8.8 liters.

But 1.8 MT 123 liters. With. on a long, flat path it will spend 5.4 liters, driving a hundred kilometers, and on busy streets the same distance will require burning 9.8 liters of gasoline.

Options for solving the problem of Lada Priora with increased idle consumption

You should not base your car’s fuel consumption on the basis of the indicators provided by the on-board computer. As is known, such technologies, especially considering that they were produced in Russia, have low accuracy. To check the actual consumption, you need to use the often practiced “from refueling to refueling” method:

  • first, the fuel tank is completely filled;
  • the flow meter counter is set to zero;
  • driving is carried out until a signal lights up on the dashboard, indicating that the fuel level is close to zero;
  • then the car is refueled again to a full tank.

As a result, you need to look at the refueling machine's meter to see how much gasoline was actually filled, then compare this data with what is displayed on the meter, and make basic calculations that will show the real consumption.

If concerns about increased consumption are confirmed, you will have to worry about replacing some components. Which ones exactly cannot be determined at random, therefore preliminary computer diagnostics and visual assessment will be required.

There is a high probability that reflashing the engine will help normalize consumption. The latest programs can reduce its value at idle to the optimal 0.5-1 liters per 100 kilometers.

However, the problem may remain unresolved even after taking all the indicated measures - cases of factory defects in Lada Priora cars, regardless of the year of manufacture, are very common. In this case, there is nothing else to do but contact representatives of the official dealer in your region.

And, finally, the best recommendation that can be given to the owner of a Priora is to seriously think about buying a car of another brand, which has much higher reliability and efficiency indicators at a comparable cost of the car itself and its service.

Fuel consumption Lada Kalina

The first Kalin prototypes appeared back in 1999, but serial production of these models began only in 2004. Initially, the car was produced in a sedan body, but later hatchbacks and station wagons were added to them. The cars were equipped with power units with volumes of 1.4 and 1.6 liters. The first made it possible to develop a power of 89 hp, the second - 81 hp. in the eight-valve version and 98 hp. in a sixteen-valve First generation cars have an exclusively manual transmission.

Since 2013, AvtoVAZ began production of the second generation Kalina, changing the appearance of the car and abandoning the sedan body (but a crossover modification appeared). The manufacturer also abandoned 1.4-liter engines, but the number of modifications with a 1.6-liter engine increased. In addition to mechanics, buyers were able to choose models with a four- or five-speed automatic transmission.

At the request of the buyer, Kalina is assembled with a 1.6-liter engine and a power of 136 hp.

What kind of gasoline should be poured into the Lada Largus, choose between 92 and 95

Many Lada Largus owners wondered what kind of gasoline to pour into their favorite “iron horse”.

You can often come across this question on various automotive forums, but no one can give a clear answer. Let's try to consider and come to a conclusion, what kind of gasoline is needed for this car?

Recommendations from the AvtoVAZ plant

Standard gas pump at a gas station


Which of these will we choose for Largus?

According to the service book and manufacturer's recommendations, Largus must be filled with fuel with a medium or high octane number. So, the question arises, what kind of gasoline should be poured into the tank - AI-92, AI-95, AI-98, or the Premium and Euro varieties? In the same manual about the fuel system it is written that it is not lower than AI-95. This is due precisely to the effect on the fuel system, which better perceives this particular marking.

Renault engine manufacturer's recommendations


The factory recommendations are duplicated on the gas tank flap cover (only 95 and 98)

Lada Largus fuel filler flap indicating the type of gasoline

Since the Largus has a Renault engine, you should listen to this manufacturer when choosing gasoline.

An exact definition was found in the service book for the K4M and K7J engines. The fuel system must be filled with gasoline marked at least A-95E.

Gasoline consumption on the dashboard of Lada Largus


To reduce consumption, the manufacturer recommends using only 92 gasoline.

This fuel is designated AI-95 Euro on the domestic market.

Expert recommendations

In 2014, this car was tested on different types of fuel. Three cars with the same characteristics, into which AI-92, AI-95 and AI-98 were poured. Each of them was tested for different indicators.

When using AI-98, the engine overheated too much and the cooling fan could not cope. Therefore, experts noted that this brand of fuel is not very suitable for use in Lada cars.

When using AI-95, there was a noticeable increase in dynamics and a drop in consumption compared to AI-92. Thus, experts noted that the ideal option is to use this particular brand of fuel.

Motorists' experience


Experience says it's 95!

Based on the experience of motorists, we can say that AI-95 becomes the optimal option for use. After switching to this brand from AI-92, the dynamics noticeably increased, and the consumption decreased by almost 25%, which cannot but please the owners.

Also, auto mechanics note that when using AI-95, there is less deposits on the walls of the combustion chambers, and the fuel system becomes clogged and fails much less often. Therefore, it is recommended to fill Largus with this type of gasoline.


Economical driving

Real fuel consumption figures and figures in technical specifications

You need to understand: not a single manufacturer indicates real fuel consumption figures. We are talking about measurements carried out according to a certain method, in order to then use the result to compare cars, different configurations, etc.

Improving your driving style in the first month of running-in

After running-in, fuel consumption on the Lada Largus can be 7 or less than 7 liters per hundred. Here we are talking about highway driving and a 16-valve engine.

Passport data on gasoline consumption of a Lada Largus car

For example, consider and compare two tables. One will indicate the fuel consumption of the Lada Largus, the other will show the figures for the Dacia Loan MCV station wagon.

Body typeCityRouteMixed
Station wagon 7/5 seats, 16 cl. (K4M) 10,16,77,9
The same, 8th grade. (11189) 10,66,78,2
Van, 16 cells (K4M) 10,46,47,9
The same, 8th grade. (11189) 10,66,78,2

Above are the data from AvtoVAZ, and in the following table are the figures announced by Renault.

Body typeCityRouteMixed
Station wagon 7 seats, 16 cl. (K4M) 9,86,37,5
The same, 8th grade. (K7M) 10,56,58,0

Let's analyze what we see:

  • Lada Largus and Dacha Logan MCV are the same car. In the version with a 16-valve internal combustion engine, the consumption must be the same, that is, the numbers in the top line of the two tables must coincide. But there are differences here, and noticeable ones.
  • None of the tables should be used as a guide during operation. However, the passport data still contains useful information: you can compare different configurations, as well as indicators “for the city” and “for the highway.”

How to use tables? Example 1

A reader asked whether fuel consumption was too high, that is, whether it complied with the standards. For the Lada Largus, fuel consumption standards are not given anywhere, just like for any other car. Now let’s look at how to use passport data:

  1. Suppose that when driving along the highway, the BC showed a consumption of 7.4 liters. We find our configuration in the table, we see the number 6.7 there. Then there will be a proportion: 6.7 is to 7.4, as 10.1 is to X.
  2. The number X is 11.2 - this is the consumption rate in the city, but only for this car, for which the readings on the highway were “7.4”.

A car with the parameters that were indicated actually exists. Its mileage is 30,000 km.

Test Largus with K4M engine

Let's use tables again for our own purposes. Example 2

Motor 11189 is more economical than the French K7M Proof:

  1. We take any column from the Renault table;
  2. We normalize the top number to the VAZ numbers: 7.9 is related to 7.5, as 8.2 is related to X.
  3. X = 8.6. This value would have been obtained if one technique had been used for the K7M engines - the same as for the ICE 11189 and K4M (top table).

The number 8.6 is greater than 8.2. So we compared the two motors. In reality, fuel consumption for the Lada Largus will be different, whether with a VAZ or with a French 8-valve.

About reducing fuel consumption during the running-in process

Imagine: there is a certain test route on which measurements are taken. As mileage increases, efficiency changes:

  • For a mileage of 30,000 km, the figure will be 9.3 liters per 100 km;
  • For 60,000 km on the same route, different figures will be obtained - 8.3 liters per 100 km.

Based on these numbers, you can roughly judge when the run-in ends.

Consumption depending on engine type

On the VAZ 2114 engine there were 2 valves for each cylinder. Compared to 16-valve counterparts, 8-valve ones cannot completely empty the burnt gases in the piston. This leads to a decrease in the efficiency of the entire engine, since during one cycle the fuel concentration in the volume burned is slightly lower. Accordingly, the energy transmitted by it will be significantly less. To accelerate to a certain speed and pass a certain section of the road, Priora will require more fuel than in the case of complete release of exhaust emissions between cycles.

If the piston stroke increases due to complete combustion and removal of gases, as in modifications 21126 and 21127, then the compression ratio also increases. This increases the efficiency of the gasoline being burned, thus increasing the power of the vehicle. An increase in piston stroke leads to an increase in engine displacement, which affects fuel consumption.

Unlike modification 21126, the next generation of engines 21127 is produced with a modified exhaust manifold. Such design changes made it possible to raise it by 8 liters. With. machine power. It is worth noting the improvement at medium and low speeds of the unit.

Reducing the total mass of the piston group and improving the crankcase ventilation system reduced the fuel consumption of the Lada Priora and improved the environmental characteristics of the engine. Harmful atmospheric emissions from the car have significantly decreased due to more intense afterburning of crankcase gases in the pistons. In addition, the mileage before the first overhaul has increased to 200 thousand km. Many claim that the average figure before restyling the power unit did not reach 150 thousand km.

Real fuel consumption figures

Some cars are produced with 8 valves in engines. There are versions with 84 hp. and 87 hp The manufacturer promises that these cars will “eat” 10.5-10.6 liters on city streets and 6.5-6.9 liters on the highway. In reality, the values ​​differ greatly.

For 84 hp engines. and 87 hp have approximately the same consumption in real conditions. The values ​​are as follows:

  • When driving in the city, in traffic jams and difficult traffic conditions - 12.4-13.8 l;
  • If you often have to drive on the highway, between cities – 8.2-8.9 liters;
  • When driving in the combined cycle - 10.1-10.9 liters.

Power plants 102 hp, 105 hp and 106 hp consume more gasoline than less powerful versions. However, the numbers are quite adequate, which contribute to fuel savings. In real conditions, the indicators are:

  • Driving on city roads – 12.6-13.9 l;
  • Driving on highways – 8.6-9.4 l;
  • Driving both on the road and on the highway – 10.5-11.6 liters.

It must be borne in mind that consumption figures fluctuate greatly, depending on environmental conditions. In winter and at low temperatures, the specified gasoline consumption standards increase.

Those cars that are equipped with engines of 102 hp, 105 hp. and 106 hp have a basic design with 16 valves. This had a good effect on the power and dynamics of the car. Unfortunately, a negative trend towards increased gasoline consumption has emerged. For all these three engine variations, the numbers are approximately the same - we list them:

  • Operating the car in the city, on a busy road – 12.5-13.6 l;
  • Driving between populated areas on the highway – 8.9-9.7 l;
  • Mixed operating cycle – 10.3-10.9 l.

About the alarm

Alarm system with auto start, allows you to start the car for 5 - 10 minutes. Moreover, usually the default is 10 minutes, but you can set it to 5, on some alarms it’s 3 minutes.

You can set it to run automatically by time, for example:

  • Will start before you arrive
  • Or by time interval (every 2 hours),
  • By temperature (warmed up - stopped - cooled down - started again).
  • Well, of course, you can start it yourself from the window in the morning (this is if the car is parked in front of the windows).

The most common are points 1 and 4, and basically no one removes the factory settings; the machine “keeps on” for 10 minutes. (it is during this time that we will calculate fuel consumption below)

Lada priora

The Lada Priora is equipped exclusively with gasoline engines of the following volumes: 1.6 liters with a power of 90, 98 and 106 horsepower, 1.8 liter with a power of 122 and 130 horsepower. The engines are combined with a five-speed manual or five-speed robotic transmission. The maximum achievable speed of the car is from 190 to 196 km/h.

  • Ivan, Orenburg. Choosing a car took quite a lot of time, I thought about Daewoo Lanos, Cherry Amulet and Priora, but in the end I settled on it, the price was right. I have a 2009 model, 1.6 l, 90 horses. The car is very average in terms of assessment: some are good, some are unfinished. But I'm driving it for now. The consumption is small, 6-9 liters.
  • Oleg, Tver. Lada Priora 2008, not bought new. Before her there was a “nine”. Priora attracted me with its low price and good build quality. I am quite tall, but the seat in the car is very comfortable. Noise insulation is good, but speed shifting is not very good. Fuel consumption is from 6 to 10 liters.
  • Timofey, Belgorod. The domestic manufacturer, of course, is taking steps to improve cars, but we are still very far from reaching a good level. Slowly, one after another, various spare parts become unusable. There is no need to talk about sound insulation at all. Consumption is low, which is good: 56 liters on the highway, 8-9 liters in the city. The car was produced in 2020, with a 1.6 liter engine.
  • Pavel, Syzran. Lada Priora 2009, 1.6 l, 98 hp It seems to me that I overpaid, but I was already tired of looking for a car and took what I had. The heating turned off after ten thousand miles, the creaking did not go away from the first day, the engine is so noisy that you can’t hear anything. Average consumption according to instrument readings is 7.5 liters per hundred.
  • Gregory, Shakhty. My husband bought me a 2007 Priora, 1.6, manual. If you compare it with other VAZ creations, then, of course, the Priora is a cut above, but in no case can you compare it with its Western or Japanese counterparts. The complete lack of sound insulation is especially annoying. Consumption is good: 6 liters on the highway, 9 liters in the city.
  • Dmitry, Stavropol. How I ended up acquiring this bucket of bolts, I don’t know, because there were good options for my money. I haven't tinkered with the mechanisms for a long time! Everything that can break breaks, there is no noise at all, the 1.6 liter engine is weak for me, but it needs a lot of fuel - 10-11 liters in the city. On country highways there were never less than eight.
  • Afanasy, Moscow. I have a 2021 Priora, 1.6, manual transmission. Good appearance and high-torque engine. But the Shumka is not good at all, everything inside creaks to the point of a headache. Consumption is 7 liters on a country highway, 9 liters in the city.
  • Roman, Samara. Lada Priora, 1.8, manual, 2021. In my day, I bought a good car, bought it new, and had no breakdowns in a year. Yes, there are shortcomings, but I don’t know why many people criticize this model, I like it. Consumption is low - 6-10 liters per 100 km.
  • Anatoly, Kaliningrad. Priora 2021, 1.6, manual. In my opinion, it is an excellent car, superior in some respects to its foreign counterparts. We like the car so much that we have already decided to buy the same one for our wife. Minimum consumption - 6-9 liters.
  • Anton, Kostroma. I bought the car second-hand, but in good condition. I really like the Lada Priora, I have almost no comments. The stiff suspension is compensated by the quality of the native roads. The interior is comfortable, but I would like more space. A 1.6 engine with a manual uses an average of 8-9 liters of gasoline.
  • Maxim, Nizhny Tagil. My Priora was not new when I bought it. The 2009 model hasn't had time to wear out yet, so I'm happy. If you do not take into account the constant noise of the engine, then everything else is fine. Because of the stiff suspension, on the dirt road you feel like you’re at a horse race. Consumption on average is 8 liters of gasoline.
  • Roman, Moscow. The 2021 Lada Priora seems to be modern, but there are almost more disadvantages than advantages. The suspension is stiff, the alternator has already been replaced, and the noise in the cabin is very loud. But the engine is surprisingly good, the 1.8 liter engine pulls quite powerfully and consumes little - 5-6 liters on the highway, 9-10 liters in the city.
  • Daniil, Perm. Lada Priora fully corresponds to price/quality indicators. Those who want everything at once should have bought expensive/foreign. I don't like the paint job and the extraneous noises in the cabin, but otherwise it's a pretty decent car. Consumption on average is 7.5 liters.

Lada priora 1.6 mt 106 hp

Fuel consumption rate per 100 km

After some restyling of the model in 2021, a 1.6-liter engine with a new fuel supply system was added to the 90 and 98-horsepower engines, which increased the maximum power produced by this engine to 106 horsepower. The acceleration of such a car to 100 km will be 11.

5 seconds. The maximum speed remained at the same level – 183 km/h. Fuel consumption per hundred kilometers in the urban cycle is 8.8 liters, on the highway – 5.5 liters. Initially, a 5-speed manual gearbox was equipped with the engine; later, a robotic gearbox was developed.

Gasoline consumption on Russian roads

  • Igor, Ivanovo. The car, in general, is not bad for our automobile industry. But there are too many “BUTs” here. Already on the third day the stove stopped working. A month later, the electric power steering failed. Moreover, the service workers said that this often happens with priors. The salon is rattling. Consumption is within 9 liters in the city, 6 liters on the highway. Model 106 hp 2021.
  • Alexander, Omsk. Lada (VAZ) Priora 1.6 MT 2021. I can’t say anything bad about the car, because it’s really cool. In terms of performance, it even surpasses foreign-made cars of the same class. Now my wife and I have decided to take a second one so that she can also travel. Her consumption is not that big. In the city it consumes no more than 9 liters of gasoline, on the highway 5-6 liters.
  • Alexander, Orel. Once again I was convinced that cars produced by VAZ are not cars, but buckets. Three weeks after purchase, all the bearings in the 2021 car began to seize. The cabin doesn't even smell like soundproofing. It will be quieter in the UAZ. The engine is weak, but consumes a fair amount of fuel. For a hundred kilometers in the city in the summer it’s about 10 liters, on the highway it was even 8 liters.
  • Vitaly, Vologda. I haven't encountered any problems in all this time. On the contrary, I was convinced that this is one of the best cars of our production. The interior is nice and comfortable, the design of the car is cool. Priora is not picky about maintenance. Despite the small engine capacity, it goes fast. Consumption on average is 7.5-8 liters.
  • Evgeniy, Moscow. Lada (VAZ) Priora 1.6 MT 2021. The car itself is good and reliable. But as for me, there is not enough space, especially in the back, although the trunk is large. During the first time of operation, the starter broke down. And on top of that, gasoline consumption was too high - 10 liters per 100 km. After reprogramming the brain, consumption dropped to 8.5 liters of fuel.

Total

The factory fuel consumption figure for Priora with 16-valve engines is 6.6-6.9 liters per mixed “hundred”. In reality, the appetite ranges from 8 to 14 liters. in winter and 5.5-11 l. in summer.

It's an environmentally responsible thing to do and will indirectly help save fuel. We believe that cars require no maintenance other than worn brake pads, tires, shock absorbers and filters. However, as high-energy ignition systems move away to the cross electrodes, the gap becomes wider and the spark is less consistent and intense. Get yourself a fresh set of spark plugs for better gas mileage. And while you're at it, check your ignition coils and wiring harness.

Vacuum leaks are easily one of the most overlooked faults because we tend to assume the worst and miss stray suction entirely. Vacuum leaks often prevent detection. Since so many under-hood jobs rely on intake manifold vacuum, there are apparently miles and miles of vacuum hoses from bumper to bumper. Vacuum hoses are dry, as are tees and other connections. And when they do, they create vacuum leaks that can disrupt the electronic engine management system.

Increased fuel consumption can be caused by malfunctions in the fuel system, in the ECM, a clogged air filter, a clogged catalyst, incorrect operation of the air purge valve, or air leaks. Tire pressure and driving style also determine energy consumption.

Real reviews from owners about fuel consumption on the Lada Priora:

You get rough or unusually high idle and less power. The result is poor fuel economy. Fuel pressure regulators are typically flight vehicle components, but they can fail. A faulty fuel pressure regulator may or may not cause too much fuel pressure. Too much means high fuel consumption and poor performance.

14: Ignition coils and seat belts

However, high-energy ignition systems and sizzling temperatures take their toll on ignition components. Coil-based ignition systems virtually eliminate ignition wires. However, many traditional coil and distributor ignition systems remain. When you change spark plugs, try checking and, if necessary, replacing the ignition wires and coils while you're at it. This keeps the entire ignition system fresh and in addition to the ignition business.

  • I am a measured driver, so the “acceleration-deceleration” mode is not for me. Fuel consumption is interesting for sporting reasons. It suits me along with the car. In fact, during the run (see above), fuel consumption per 100 km never exceeded 8 liters in mixed mode.

As always, check the manufacturer's recommendation. Most never consider a positive PCV valve in the same thought process as fuel economy, but it can have an effect. This can also be a huge source of vacuum leaks.

It will also cost you in fuel economy since fuel has a high evaporation rate. A loose fill cap allows fuel to evaporate, which also causes problems with the evaporative emissions system. Cooling fans can either increase fuel consumption or completely destroy it. Inflexible steel fans will cost you power and fuel economy. The most efficient engine cooling fan is the thermostatic clutch fan. It engages and operates when needed and freewheels when not needed.

  • I pay close attention to fuel consumption. I record all gas stations and often travel loaded. When loading, obviously a liter can be lost in fuel consumption. And so, within 7.5 liters, moreover, I did not observe gasoline consumption.
  • I have an eight valve engine. And AI-92. Therefore, sometimes it comes out within 8.5 liters per hundred km. But I noticed that if you drive calmly, the fuel consumption per 100 km is much less - about 6.5 liters.
  • I like the motor. Yes, gasoline consumption per 100 km may vary. It all depends on the load, starts from traffic lights, and the time of year. But on average, over six months, I calculated that I met 7 liters in fuel consumption. Worthy!

18: Still fooling around with glasses?

Electric thermostatic cooling fans remain one of the biggest fuel savings. If you choose and take proper care, you can improve cooling and improve fuel economy. If you drive a classic car and are still traveling interstate with breakpoints, you are burning an excessive amount of fuel. Every time a spark plug misses, that's precious fuel lost in the tailpipe.

19: Live without air conditioning

When the temperature turns the thermometer red, start your car's air conditioning.

  • I set a goal, and after driving 500 km on the highway, I got a gas mileage of less than 6 liters. But sometimes in the city it eats about 10 liters, which corresponds to the plant’s data.
  • In a big city, my average fuel consumption is always within eight liters. There are no revelations. On the highway, fuel consumption per 100 km varies - 6-6.5 liters.
  • I talked to my neighbor. Compared to my 16 valves, his 8 valves consume more per liter.

20: reduced friction = fuel savings

Motorists run the air conditioning even when the temperature is in the balmy 70s because we like things. Engine technology has brought us excellent aftermarket components that reduce internal friction, free up energy and improve fuel economy. Roller camshaft and rocker arm technology improves fuel economy as they significantly reduce internal friction. If you follow this logic even further with needle bearings and rods, you will reduce friction even further.

  • I drive a lot, and the terrain is hilly, sometimes I have to rev the engine. Fuel consumption differs for equal mileage on the plains and hills, about a liter per hundred. But you can keep it within 7 liters at a calm pace of movement.

Lada Priora, in operation for 5 years, AI-95:

  • Gasoline helps to get the return, and fuel consumption is close to the passport data. In the city rhythm I always have a consumption of about 9 liters per 100 km, whatever one may say, but I’m happy.

Lada Priora, 1.6 16-valve engine. More often I drive “empty” - home and work.

  • The engine is economical, but in moderation. Fuel consumption increases sharply at high speeds. But in the city (I drive along a stable route), everything is predictable - 8.5 liters. So it’s not a loss.
  • I read something, I don’t understand, everyone is doing so smoothly. I have the same engine, 16 valves, but at 120 km/h it comes out to 8.5 liters per 100 km. And in the city it’s still 10.5. Although I looked at the factory data - there are not very big differences in fuel consumption. I noticed that fuel consumption increases significantly if the needle does not go less than three thousand on the tachometer.

I have owned it for 4 years, 48,000 km mileage, 1.6 petrol, 16 valves:

  • I knew from the fuel consumption that the engine was more advanced. But the fuel consumption itself was high, the factory one did not inspire confidence. Therefore, I observed, and if on the highway the gasoline consumption was close to the factory indicator - about 6 liters, then when driving under a load, in the city - the fuel consumption clearly went off scale for 10 liters. But there are no complaints, fuel consumption is fair and this is the norm.

The main reasons for high fuel consumption on the Lada Kalina

There are quite a few reasons, but in this article we will try to consider them all. This is primarily due to improper operation of the vehicle and untimely maintenance. So, what are the reasons for the high fuel consumption of the Lada Kalina:

  1. Air filter element (air filter) is clogged.
  2. Breakdown in the power system.
  3. Failure of spark plugs.
  4. Malfunction of the throttle or malfunction of its elements.
  5. The idle speed controller has failed.
  6. The throttle valve (BDZ - throttle valve block) does not close tightly or completely (dirty or mechanical failure).
  7. Malfunction of one of the sensors: temperature, oxygen or oil pressure.
  8. Injector leakage.
  9. Malfunction of the fuel pressure regulator.
  10. The ECU controller has failed.
  11. Compression has dropped.
  12. One of the following elements is faulty or wear-related: valves, valve guides, piston rings, compression rings, valve seats.
  13. Increased exhaust gas outlet resistance.
  14. The fuel filter is clogged (about replacing it here), and it is located under the bottom of the car.
  15. Late ignition; an angle shift of 1º increases flow rate by 1%;

How to diagnose problems

13.3 liters per hundred is a lot even for the economical Kalina, even for driving in traffic jams

Diagnostics of faults should be carried out step by step until the cause of failure of a particular part that affects the increase in consumption is determined:

  1. Checking the air filter. If there are brown deposits on it, it should be replaced. Scheduled replacement is carried out every 20,000 km.
  2. Fuel leaks or smell indicate a leak in the power supply system.
  3. Spark plugs should be checked on a special stand. It is also necessary to clean the carbon deposits and set the gap. If you need to replace the spark plugs.
  4. It is easy to diagnose a throttle malfunction; you just need to press the gas pedal with the ignition off. If there is jamming, then there is a system malfunction.
  5. The Check signal means a malfunction in the idle circuit.
  6. It is worth removing the throttle corrugation and shining a light into the damper to check for any cracks.
  7. It's worth checking the injectors.
  8. It's worth checking the ignition coils.
  9. All sensors will be checked with an ohmmeter to ensure they are working properly.
  10. The controller is checked by replacing it with a known good one.
  11. Check engine compression.
  12. We diagnose the exhaust system for dents, deformations or breakdowns.

Elimination methods

To troubleshoot problems, it is necessary to replace broken or failed parts. If the malfunction cannot be resolved, you should contact a fuel specialist; you may need to adjust the injection.

Another troubleshooting option is to flash the control unit firmware. For the Lada Kalina, this is normal practice when errors occur in the ECU (error 4 is a fairly common occurrence). This malfunction can be treated by adding new software to the unit.

Removing and checking the idle air regulator

We remove the idle air control to check and replace. With the ignition off, release the latch. ...disconnect the engine management system wiring harness block from the regulator. Terminals “A”, “B”, “C” and “D” of the wiring harness block are connected, respectively, to terminals “67”, “66”, “65” and “64” of the controller. When the ignition is turned on, the voltage values ​​(regulator control output signals) at these terminals change chaotically and therefore cannot be checked.

Using a Phillips screwdriver, unscrew the two screws securing the regulator to the throttle assembly...

...and remove the regulator from the throttle assembly socket.

The connection between the regulator and the throttle assembly is sealed with a rubber ring. Using a tester (in ohmmeter mode), we measure the resistance between the terminals of the regulator connector. For a working regulator, the resistance between terminals “A” and “B”, as well as “C” and “D” should be 40–80 ohms. Install the idle air control in the reverse order. Before installing a new regulator...

...using a caliper we check the distance between the end of the valve needle and the supporting surface of the regulator flange. The distance should be no more than 23 mm. This is necessary in order not to damage the regulator during installation - the regulator needle should not rest against the seat of the throttle assembly. It is necessary to take into account that if the specified distance for the new regulator is more than 23 mm, then it will be possible to retract the locking needle into the regulator only with the help of a special tester (at a service station). Before installing the idle air regulator, clean the valve seat, air duct and surface for the sealing ring in the throttle assembly. Apply a thin layer of engine oil to the new regulator O-ring.

The reliable carburetor engine control circuit has long been supplanted by flexible electronics. The latter consists of a control unit and sensors operating according to a specific program. This trend has made it possible to achieve an increase in power and a decrease in fuel consumption. However, with the advent of electronics, the control system has become more vulnerable to malfunctions.

Technical reasons for increased fuel consumption

Despite the fact that VAZ has stepped far forward in improving its products, many unresolved problems remain. And some of them have a direct impact on the amount of gasoline consumed.

Injector diagram (fuel supply to combustion chambers)

All influencing factors can be divided into “hardware” and “software”. This classification was the result of the use of an injection engine, as well as the abundance of sensors in the car’s design.

Incorrectly selected fuel

It is recommended to fill AvtoVAZ engines with 95-grade gasoline only. Only then will the engine control system begin to correctly calculate the parameters for preparing the fuel mixture. Therefore, when using gasoline with an octane number below 95, fuel consumption will increase and foreign vibrations may appear in its operation.

Electronic system errors

They can be considered one of the simplest situations, since they can be corrected by simply contacting a specialized service center. Problems of this kind arise for the simple reason that some sensors that are used to prepare the working mixture begin to function incorrectly.

Diagnosis of car electronic systems

In particular, we are talking about

  1. temperature sensors,
  2. throttle position sensors,
  3. as well as mass air flow.

In the latter case, its breakdown may be due to the fact that the air filter has not been changed for a long time. And, of course, incorrect readings can result from false information from the oxygen sensor, which is also simply called a lambda probe.

All this can lead to both the preparation of a “lean” and “rich” mixture. As a result, power may be lost or fuel consumption may increase. A malfunction can be detected by diagnosing each sensor separately.

Fuel system pressure

In Fig. car fuel frame and receiver

This is another common breakdown. The fact is that the pressure level can be too high or low, although the second option is much more common. This can be determined when the engine loses power and you have to drive at higher speeds to maintain the desired dynamics. This all significantly increases fuel consumption.

If you have problems with the fuel rail, the car may not start.

Injector problem

If you do not monitor the condition of the power unit, this will lead to shortcomings in its operation. Most often, this concerns contamination of the injectors, which is followed by poor supply of the working mixture, so that the engine begins to “triple”, and you try to compensate for this by increasing the speed.

Catalyst destruction

Similar results occur when the catalyst burns out or even breaks down. Without going into detail about the specifics of this situation, we can simply conclude that if the catalyst is contaminated, a “rich” mixture will form. After this, additional heating of the catalyst occurs, reducing its service life and reducing engine power. Fuel consumption will be maximum.

Motor temperature

In addition to all of the above, it would be a good idea to constantly monitor the engine temperature. If it is above 103 degrees, then the mixture will not be of sufficient quality. The engine will begin to operate on a “lean” mixture, reducing its power and increasing gasoline consumption.

The main drawback is that the instrument panel on the Lada Granta does not have a real-time indication of the engine temperature, read how this can be fixed here.

If the engine has not yet warmed up, this leads to an increase in consumption due to the “enrichment” of the mixture. The level of overspending reaches 20 percent. In most cases, the cause must be found in the thermostat.

Incorrect engine operation

Increased fuel consumption may be due to a “broken” engine. That is, the engine is worn out. The main symptoms of engine wear will be:

  • There is no compression.
  • Maslozhor.
  • Other.
  • bad dynamics
  • erratic engine operation

Air filter dirty

And, of course, we must not forget that if air flows poorly through this filter, the effect of “oxygen starvation” will begin. This will entail a significant excess of gasoline consumption.

How to reduce consumption using “economical firmware”?

The only advice would be not to perform these procedures if you have a valid car warranty. In addition, only professionals should do this. If you do this yourself, then you need to first study this topic in detail.

Fuel system

It is in the fuel system that the mystery of increased engine fuel consumption may lie.
First of all, you need to check the pressure in the fuel pipes and fuel rail. Several parts that have failed for various reasons can contribute to this effect. Dirty fuel module mesh

The first two items to check are the fuel pump and the fuel filter. Dismantling the fuel module may be a clue, since the filter mesh could simply be clogged.

But the filter is not visible, so you just have to change it.

Low-quality fuel, which is saturated in the modern gasoline market, as well as low-quality spare parts can cause this unit to fail ahead of time.

Dirty fuel filter

The second element that can cause this is the throttle valve. Contamination of this element can lead to its position jamming and increased consumption. The solution is to dismantle and clean the throttle.

A dirty throttle valve can be easily cleaned with WD-40

If the fuel system has been checked, all elements have been replaced and cleaned, but the consumption is still high, you should pay attention to the injectors.

Sedan and liftback body

The Lada Granta sedan went on sale in 2011 and immediately became a popular car model. The reason for this was the massive purchases of this particular car: two years after its release, every 15 purchased car was a Lada Granta sedan. Of the three known trim levels - Standard, Normal and Luxury, the most affordable option is the standard. The engine capacity is 1.6 liters and the power is 82 hp. With. makes this 4-door model not only a budget, but also a practical economy class car. And the average gasoline consumption of the Lada Granta sedan is 7.5 liters per 100 kilometers.

Before the release of the new Lada model, many became interested in how much it would change. As a result, the technical characteristics of the liftback are not very different from the sedan. This car entered the market in 2014. The main changes are visible in the exterior of the car and in the 5-door configuration. Other functional devices remained the same or were improved. The lack of changes can be seen on the car configuration, which was transferred from the Grant sedan. Fuel consumption in such cars is slightly higher, as engine power has increased.

Car color

Some motorists argue that the cost may directly depend on the color of the car. For example, a light model consumes much less than its dark counterpart, but this is far from a guarantee.

American scientists have proven the influence of color. They found that this manifests itself especially in the warm season.

When the car heats up, it spends a lot of energy cooling the interior and, of course, fuel consumption increases

In the interiors of dark cars, during the hot season, the temperature was several degrees higher than in light models. That is, the fuel consumption of the Priora station wagon (per hundred) in the summer will be less.

It's a difficult time of year for cars. Priora fuel consumption can vary significantly. The 16 valve Priora consumes more in winter. Firstly, when the engine is not warmed up, the gasoline consumption of the Lada Priora will be higher.

Secondly, the increased complexity of roads that require the car to drift also increases fuel consumption. Thirdly, speed. The slower the car moves, the more gasoline it uses.

Lada Priora, which has 16 valves, is overall more economical than other cars with similar technical characteristics. In addition, if you wish, you can always convert it to gas consumption and significantly save your family budget.
