What kind of gasoline should I put in an 8 valve grant?

What gasoline to use in Lada Granta, manufacturer's recommendations

There is an opinion among owners of domestic cars that their vehicles can be fueled with almost any fuel that is on the market. This statement dates back to those times when, apart from the “VAZ classics,” nothing more modern could be found on the roads.

Only 95 gasoline?

AvtoVAZ recommends 95 type gasoline

Modern VAZ cars are equipped with a large number of electronic systems that require good treatment and quality care. This also applies to the brand of fuel that is filled into the tank.

According to the official documentation of the Lada Grant, this car must consume exclusively A-95 gasoline.

But is it worth adhering to the recommendation, or can you deviate from it a little? Now we will find out about this.

Is it possible to refuel with A-92 gasoline?

There is such a thing as octane number, which is determined in digital terms by the name of the fuel. If the vehicle in question is recommended to use 95 gasoline, there are reasons for this.

The fact is that the engine, which is designed for A-95 gasoline, can start working with any type of fuel. He won't do octane tests. Instead, to put it simply, it will treat any gasoline as if it were A-95, compressing it accordingly.

And, given that A-92 fuel has an octane rating of three units less, its possible compression ratio may be lower than in the case of the recommended fuel. This may not be noticeable if the engine has already traveled more than one or two hundred thousand kilometers, since the compression performance of the combustion chamber decreases somewhat.

Try to refuel at large chain gas stations.

If you fill in with high-quality 92-grade gasoline, then no errors will appear on the instrument panel after starting the engine; this is precisely the main argument of those who like to refuel with gasoline with a lower octane number.

But, in the case of proper technical condition, as well as a new car, it will compress the working mixture to the maximum. And gasoline with a lower grade is not designed for this. So, if you do not want to hear the sounds of detonation, and also eliminate premature wear of car parts in the near future, then you should listen to the recommendations of the car, exactly what is written in the operating instructions

And the operating instructions for the Lada Grant indicate gasoline of at least 95.

Simply put, the result of using any fuel with a lower grade will be the appearance of unintended detonations and difficulty starting a cold engine. They are very small local explosions that damage the condition of the cylinder and, to some extent, the piston. Moreover, all this can lead to increased wear and, most importantly, increased fuel consumption. So any attempts to save on cheaper gasoline will be doomed to failure.

What then to do with “older” gasoline?

Let's fill up with 98?

If you consider the above information, you might think that it would then be advisable to fill your car with gasoline with a higher octane number. For example, this could be the A-98, which is the standard for many modern foreign-made cars.

But here again we will have to disappoint you, since the mechanism requires a clear and correct attitude towards itself. Therefore, if the compression ratio is designed for A-95, then A-98 gasoline will be compressed to exactly the same level. And the potential of this fuel can only be revealed when its compression force is higher, which the Lada Grant engine is not designed for.

The result of refueling with 98-grade gasoline will be the inability to use its properties to the maximum, and you will simply lose your money due to the difference in the cost of gasoline of different brands.

Features of the national gas station

But, this is all theory. The fact is that in our country the fuel situation is not as rosy as one might expect. Often, the required octane number in the fuel sold is achieved by using special chemicals called “additives” (as in the video above). Thus, a chemical analysis will show that this number corresponds to the brand, while the car may not want to work fully with this gasoline. In this case, you will have to drain all the gasoline from the tank and clean it.

And most domestic oil refineries do not have equipment that could process oil into gasoline grades higher than A-92. It is for this reason that “there is a popular opinion” that there is basically no difference between brands with an octane number greater than 92.

But the cost of gasoline will vary significantly. In addition, the savings on the “correct” fuel are not so high in terms of its consumption, which does not cover additional material costs. The exception is the exclusively urban driving cycle, where trips are made mainly in low gears and, often, at high speeds of the power unit.

However, this is the opinion of people, but not of automobile experts. And improper operation is rarely associated with one’s own carelessness. Instead, complaints begin to arise about the build quality of the machine itself.

Conclusions and opinions of Lada Granta owners

Gas tank flap of Lada Granta So what fuel should you choose for Lada Granta engines?

Here the answer will be very simple. If you have a gas station in your city that guarantees the quality of the gasoline it sells, then you should only buy 95 gasoline. In addition, it would not be superfluous to carry out compression control at least once every fifty thousand kilometers. This will allow you to find out about problems in time, if any, and fix them immediately. This way, the car can constantly use fuel to the maximum.

Is it possible to fill 92 gasoline instead of 95 in a Lada Granta, which is better?

test measurement of the real octane number of 92 gasoline

The video below shows the process of measuring the octane number of gasoline that was purchased at regular gas stations in Novosibirsk. Only one sampler showed the presence of truly 92-grade gasoline.

And the operating instructions for the Lada Grant indicate gasoline of at least 95.

Is it possible to use 92-A for turbocharged engine systems?

Good gasoline is considered to be gasoline from the manufacturer Lukoil. 92-A and 95-A are a quality product compared to other types of gasoline. Using these types of gasoline, the driver consumes less fuel, and there is also a slight impact on the spark plugs.

Many car owners believe that even for turbocharged engine systems, both 95-A and 92-A are suitable. But experts recommend using 95 gasoline for engines that contain additional devices. Therefore, when deciding whether the Lada Grant can be filled with 92 gasoline if it contains a turbocharged engine, it is better to stop at 95-A.

What kind of gasoline is better to put in the tank of a Lada Granta?

An experienced driver knows what kind of gasoline to fill in the Lada Granta by monitoring the reaction of his car to different types of fuel. Properly selected gasoline plays an important role in maintaining the functionality of the mechanisms of the Lada Granta. Choosing a high-quality option from hundreds of similar offers is a real art that the driver will master only with time.

Criteria for choosing gasoline

When choosing the appropriate fuel option, the car owner must take a number of rules as a basis:

If the Lada Granta car will be used both in warm and cold seasons, it is recommended to pay attention to the volatility class of the purchased gasoline. Requirements for this substance vary depending on the area of operation, but for the most part suppliers strive to offer a universal product, which should be chosen for the Lada Granta car.
Gasoline should not contain dangerous impurities such as lead, iron or manganese. Such a product is rightfully considered to be of poor quality and can damage the car’s fuel system.
Most manufacturers, in an effort to protect the tank from corrosion and destruction, add so-called additives to gasoline. However, you should not add such a substance yourself to the finished product. It would be more advisable to purchase a premium product, which will provide maximum protection.

In real life, Lada Grant owners have a choice of two brands of gasoline poured into the tank: 92 and 95. Domestic drivers use both options with equal success, but determining the best one is quite difficult.

The manufacturer of the Lada Granta recommends using 95 gasoline due to its high quality. This gasoline is supplied purified, without foreign impurities. In addition, it has cleansing properties, to which there is a rather ambivalent attitude. On the one hand, such fuel does not allow dust and dirt to penetrate into the gas tank container, on the other hand, with constant use it has a destructive effect on the metal itself.

92nd gasoline is rightfully considered much more benign, as it contains nothing other than the raw material required by the manufacturing technology. In addition, refilling this product will be an order of magnitude cheaper than its 95 equivalent.

When choosing the right gasoline, the car owner must pay attention to the recommendations given by the manufacturer and adapt them to his region and the needs of the car.

How to fill your own gasoline?

Having decided which gasoline to fill, the motorist can go to a gas station to get fuel, where a professional gas station attendant will come to the rescue. However, in some cases he will have to fill the gasoline himself.

In order not to be left without fuel at the most unpredictable moment, it is important to constantly check the fill level of the fuel tank.

Refueling may be required along the way, so you should always have a canister and funnel with you

You should refuel when there is less than half the tank left. Many inexperienced drivers prefer to drive until the light on the dashboard lights up, indicating that the tank is almost empty. This practice is quite risky and can significantly harm the motor system. Gasoline cools the fuel pump, which, if overheated, will simply burst. If the tank is filled according to the rules, you can safely go to the gas station.

When approaching a gas station, it is important to park the car correctly in front of the gas station with the side on which the gas tank cap is located. It is advisable to park the car in such a way that the gas tank and gas station are at the same level. After this, you should unscrew the gas tank cap and insert a refueling nozzle of the appropriate brand into it.

After this, you need to make a payment and indicate how many liters of fuel need to be filled into the Lada car. Returning to the car, you need to press the lever on the gun, then the fuel will be supplied automatically.

At the same time, the motorist must know how to drain gasoline from the tank if he comes across a low-quality product. You can do this in three main ways:

directly through the fuel pump;
through the bottom gas tank cap;
through the neck of the fuel tank.

These methods have long been well known, but today there is a more progressive method using a bulb pump. Externally, this device resembles a device for changing pressure and works on a similar principle. A rubber hose is placed in a container with gasoline, and the bulb here acts as a pump pumping the liquid. The second end of the hose is located in the tank into which gasoline will be drained. The entire procedure, depending on how large the tank volume is, can take from half an hour to an hour and, most importantly, will not harm the fuel system.

Car owners are always interested in the specifics of maintaining their car. This section contains detailed information about car maintenance: the secrets of changing the oil in the gearbox are revealed, and there are tips for those who want to replace the fuel filter. After studying the materials in this section of our website, you will be able to understand the difference in carrying out the first, second and third maintenance. Owners of a Lada Granta car will find here information about all the nuances of caring for their “swallow”.

What does the instruction manual say?

What kind of gasoline should I fill in the Lada Granta? Open the instruction manual in Appendix 1. Look at the text: the brand of recommended gasoline is “Premium 95” or “Premium Euro 5” and two links to GOST standards. Why such a recommendation-restrictive proposal for fuel?

Let's look at some points related to this limitation. The first note is the requirement to ensure the necessary flammability at low temperatures.

It follows from this that gasoline must be of the required volatility class. At the same time, in different regions of the country this requirement is taken into account, and the volatility classes of gasoline differ from each other depending on location. The second obstacle to the use of lower octane gasoline is the presence of metal and organic particles in it, which act as anti-knock agents. These particles contain lead, cadmium, manganese, iron and other metals.

High-octane gasoline is characterized by the introduction of various additive materials. These additives save you from soot, corrosive destruction, and various deposits. However, these additives can only be added by the fuel manufacturer. Naturally, you can do this yourself, but this is not recommended (the proportion may not be correct).

Is it possible to fill 92 gasoline instead of 95 in a Lada Granta, which is better? - Behind the wheel

Car manufacturers indicate in the accompanying documentation the brand of gasoline recommended for this vehicle. Two brands are indicated, for example, the recommended gasoline is A-95, and the acceptable gasoline is A-92.

Let's consider how important it is to use a brand of fuel with a high octane number, and what the consequences of refueling with low-quality gasoline will be.

Octane number and detonation

Any gasoline has several basic parameters:

A composition that includes parts of aromatic hydrocarbons, organic compounds containing oxygen, and benzene.
Percentage of sulfur content that forms active acids. They destroy engine parts, the exhaust system, and the catalyst.
An indicator characterizing the ability of gasoline to resist detonation, or octane number.

Detonation is the random ignition of the fuel mixture during compression.

Both brands of gasoline - 92 and 95, have different octane numbers:

Driver habits that lead to higher fuel consumption Constantly rising gasoline prices are forcing drivers to look for new ways to save money. However, few people know that...

What happens if you fill in 92 instead of 95?

Many car enthusiasts ask the question: is it possible to replace 95 gasoline with 92 gasoline? Experts and manufacturers do not give a clear answer.

Mechanics say that for normal and long-term operation of the car’s power unit, it is necessary to follow the manufacturer’s recommendations. Otherwise, the engine life will be reduced and unscheduled repairs will be required.

Manufacturers recommend following fuel quality recommendations for several reasons:

Firstly, the quality of the A-92 does not meet the standards at every gas station.
Secondly, modern turbocharged engines are very fuel sensitive and are tuned to a high compression ratio. Low octane gasoline in such engines can do more harm than good.

4 Myths That Make You Waste Fuel There are several common myths that can cause even experienced drivers to spend significant...

Will you be able to save money?

Is there any reason to refuel with 92-octane gasoline instead of A-95 in order to save money?

It is estimated that in a year a car enthusiast can save about 3 thousand rubles by choosing fuel with a low octane number. But this year the vehicle engine will work under increased load.

If you use the wrong fuel, the following problems will occur:

formation of carbon deposits in the combustion chamber;
rapid wear of rubbing engine parts;
engine running intermittently.

Such consequences will lead to the need for early engine repairs, which will far exceed the saved rubles.

To summarize, there are several recommendations:

Fuel the car only with the gasoline for which it is designed;
fuel with a low octane number reduces the power of the power unit;
new engines are more capricious and require high-octane fuel.

5 tips on how to refuel your car correctly Refueling your car - it would seem, what could be easier? However, not all modern drivers know how to properly...

It is not recommended to pour A-92 into new engines designed for 95, as you may lose the warranty right to repair the car. And the thrifty car owner will pay the full cost for repairing the damaged power unit. Consequently, the desire to save will lead to waste.

What gasoline to use in Lada Granta, manufacturer's recommendations

Which gasoline is better: 92 or 95?

Some car brands support both 92 and 95 types of gasoline. In order to find out whether there is any significant difference between these types (and whether it is permissible to refuel a car for which the octane number recommended by the manufacturer is 95, 92 type), you first need to clarify the issue regarding the octane number. How does the functioning of the internal combustion engine depend on it?

There is an opinion that the type of gasoline clearly determines the quality of the fuel - higher means better, and the mixture burns more efficiently. However, this is not true.

The first thing on which the combustion efficiency of the mixture depends is the engine itself - to be more precise, its adaptation to 92 or 95 type gasoline.

After all, an increase in the octane number determines the duration of combustion of the mixture, but, what is even more significant, the power (due to the fact that combustion begins in the case of greater compression).

Due to the fact that the 95 is able to endure greater pressure before it begins to burn (unlike the 92), it is able to burn longer, which is an additional increase in the power of the machine.

However, if the engine is not adapted to work with high-octane gasoline (or vice versa, with gasoline of a lower octane number than that recommended by the manufacturer), the engine efficiency, on the contrary, will decrease significantly - and this is clearly felt.

This occurs due to premature detonation of gasoline with a low octane number, which ultimately does not burn completely.

In other words, when choosing fuel to fill the gas tank, the first thing to consider is what type of gasoline the car manufacturer recommended. Next, we will take a closer look at whether or not it is worth using different types of fuel for a number of cases.

The manufacturer recommended both 92 and 95

Some car models (it would be more correct to say “some designs of the engines of these cars”) allow you to refuel the car with both 92 and 95 types of gasoline. For example, a large list of mid-size sedans and crossovers (Hyundai Solaris, Toyota Corolla, Kia Rio, etc.) allows the use of both types of gasoline.

However, the question arises - which type is preferable? We can answer unequivocally – type 95. Longer combustion means increased efficiency. Moreover, in this case it is not always planned to accelerate faster or provide increased speed.

On the contrary, it is necessary to fill in 95-grade gasoline, adhering to the current driving style and dynamics solely for the purpose of saving fuel.

For this reason, often the increased price of 95 gasoline ends up being offset by its reduced consumption (of course, if the engine is adapted for this type of fuel). Diesel engines, however, will in any case be even more economical.

Drivers' opinion

If you study the reviews of Granta car owners, there is complete confusion here. Some firmly claim that they are pouring AI-92

and it drives fine without any problems.
However, additional detonation is noted in the combustion chamber. The latter assure 100% that it is AI-95
, so they observe a slight decrease in fuel consumption.

And a third group has formed that fills in 50/50 AI-92 and AI-95, and what they get in the tank is who knows what. Such mixing seems understandable from the point of banal logic: reduction in detonation and average fuel consumption, but still it’s not worth mixing.

Drivers who purposefully fill up with AI-92 do not feel any significant differences in the dynamics of the car, engine performance and fuel consumption. The only thing that this replacement of the recommended fuel can clearly affect is its fuel system.

What kind of gasoline should I put in the Lada Granta: 92 or 95?

Very often, car owners wonder what kind of gasoline to fill in Granta: 92 or 95. Sometimes, even before buying a domestic car, a motorist asks the question what brand of gasoline to fill in his future car.

In fact, it is very difficult to understand which gasoline is suitable for which car brand. Most often, drivers cannot choose between AI-92 and AI-95. It is absolutely normal that everyone is trying to save money, and even more so on gasoline, on which you have to spend a large percentage of your salary every month.

Based on this, most motorists choose AI-92. If you compare the price per liter of AI-92 and AI-95, the difference will seem insignificant, but if you multiply the price per liter by the number of liters of gasoline that is consumed during the month, the difference is significant.

If you visit a car service center and ask a question about what gasoline is suitable for the Lada Granta, you will receive the answer that the car must be refueled according to the recommendations of the company that produces this brand of car.

How does the car manual answer this question?

So, to answer the question of whether it is possible to fill Granta with 92 gasoline, which worries many motorists, you should open the instructions on Appendix 1, which states that the recommended gasoline is “Premium 95” or “Premium Euro 5”. Why do the instructions contain such strict restrictions regarding gasoline?

Let's figure it out. The first note states that the required flammability at low temperatures must be ensured.

It follows from this that fuel must be selected of a certain volatility class. In different regions of the Russian Federation, this requirement is adhered to differently, and fuel volatility classes differ from each other based on location.

The second obstacle to the use of low-octane gasoline is various metal and organic particles, which are anti-knock agents and are contained in gasoline. The presence of lead, cadmium, manganese, iron and other metals can be observed in the particles.

Various additive materials are introduced into high-octane gasoline to prevent the formation of soot, various deposits and corrosion. But these substances can only be included in gasoline by its manufacturer. Every motorist can do this, but experts do not recommend doing this, since substances can be introduced in the wrong proportion.

What do drivers think about this?

If you read the reviews of the Lada Granta owners themselves, you may encounter some contradictions. Some argue that AI-92 gasoline is perfect for Lada, except that detonation appears in the combustion chamber.

Other drivers argue that only AI-95 is suitable for the Lada Granta, and even note that it is this gasoline that helps save on fuel consumption.

This octane number of gasoline has a positive effect on the fuel consumption of a car. If the average speed of a car is from 90 to 100 km/h, using 95 gasoline, about 5.5 liters of gasoline are consumed.

There is a third group of car owners who fill the tank with gasoline of both brands, which is why the results are not very good. Drivers mix two types of gasoline in order to reduce detonation and average gasoline consumption, but experts still do not recommend mixing different types of gasoline.

Car owners who buy AI-92 do not see a significant difference in the car's dynamics, engine performance and gasoline consumption. If you replace the fuel recommended in the instructions for use with AI-92, then the only difference will be the effect on the fuel system.

Is it possible to fill Grant 92 with gasoline?

Other car enthusiasts claim that they see no difference between using AI-92 and AI-95, and the engine in both cases will work almost the same. But everyone knows that using 92-octane gasoline leads to contamination of the engine system and spark plugs.

But, without taking this fact into account, many Russian motorists advise filling the Lada Granta with AI-92. Let's figure out whether the Lada Granta 92 can be filled with gasoline.

Many oil refineries located in Russia do not have the technologies and equipment that can produce high-quality 95-A gasoline.

Therefore, to create 95-grade gasoline, specialized additives are used that gasoline contains. The more such additives are contained in gasoline, the more negative the impact of the use of such gasoline on the operation of the engine and the entire vehicle system.

Well-made pure 92-A gasoline is much more suitable for any car, including the Lada Granta. There are still several factories in the Russian Federation that produce high-quality gasoline up to 98.

Most motorists advise you to familiarize yourself with information about gas stations that are in your city in order to understand what type of gasoline to buy. You should find out where these gas stations purchase fuel, as well as who produces this gasoline and what quality it is.

If you read this information in advance, you will be able to avoid problems that may arise with the engine due to the use of low quality fuel.

So, gasoline 92-A has the following features:

• leads to contamination of the engine system and spark plugs;

• has low cost;

• does not negatively affect the dynamics of the car;

• does not affect engine operation.

There's not much going on at 21127. It becomes more lively, but it’s not worth the overpayment, IMHO.

They bring me 100 from LUKoil, no problems so far, engine 21116

98 is possible, just a waste of money, it says 95th, lei 95th

The 8 valve runs well on it. Nothing will happen. I drove about 10,000 kilometers on it. But the 16-valve engine does not perform well on pure 98. A mixture of 98 and 95 in the region of 96-96.5 works well for it: it spins well, the engine runs quieter and softer. It’s unpleasant to drive a clean 95m Lukoilovsky after this mixture: like a tractor in comparison. Overpayment of 50 rubles when refueling

30 liters. At one gas station I pour 98 and then top up with 95)

in our realities - with gasoline becoming more expensive, you need to buy Lukoil 100 gasoline))) but it’s better to switch to LPG

Fill it in, 98 is better than 92. Maybe 98 will turn out to be 95 in real life. And about the warmed up valves from 98 - these are stories.

On the contrary, the valves burn due to low octane number. Because the mixture burns out at the inlet. That's right, stories. Both 98 and 100 can be poured, nothing will happen, the ECU will correct the UOS

Moreover, if the Grant is equipped with a 11186 engine, high-octane gasoline is better than detonation.

your theory is not correct, high-octane gasoline burns more slowly and therefore there is less detonation

High-actane gasoline is more resistant to detonation (self-ignition); the burning rate has nothing to do with it!

and are these values independent of each other? During normal engine operation, the working mixture enters the cylinder, is ignited by a spark, and the flame front propagates at a speed of 10-20 m/sec. At the beginning of the power stroke, temperature and pressure, due to the ignition of part of the fuel, begin to increase; if the fuel has low anti-knock resistance (low octane number), then the rest of the mixture begins to burn explosively - at a speed of 1500-2500 m/sec. (100 times more than during normal combustion)

That’s the point: under normal conditions, ignition occurs with a spark, but with low-actane gasoline, self-ignition of the combustible mixture occurs not in the center of the combustion chamber, but in random places, which leads to overheating of parts and possible destruction! But the burning rate of 92 and 98 will be the same, the only difference is that 92 will detonate before 98!

if the burning rate is the same, why then is there an ignition advance, which the ECU constantly adjusts, and since when did engines running 76 gasoline begin to run without spark plugs, let’s say an engine running on 92 is filled with 98, both without ignition do not detonate, but for 98 the ECU will increase the OZ , why, if in your opinion the burning rate is the same?
