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 in 92 gasoline instead of 95?
Now let's return to the main question. Let us immediately note that it is impossible to accurately determine which brand of gasoline is better - 92 or 95. Provided that both types of fuel are of high quality, the gasoline for which its engine is configured will be good for a particular car.
For example, if you fill the tank with fuel with an octane rating lower than the recommended one, the mixture in the combustion chamber will ignite before the required time. That is, gasoline will burn while the intake valves are closing, and not after. This means that part of the energy obtained from the explosion of the air-fuel mixture will be wasted, and the detonation process itself will add problems: the engine will operate unstably, rubbing parts will wear out faster, and carbon deposits will form on the cylinder walls. From this it follows that there is no need to fill AI 92 gasoline into a car whose engine is designed for 95 gasoline.
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.
More options
It can be noted that the fuel you fill into your car will greatly depend on where you do it. So, if refueling takes place somewhere far away (in the outback), there is no certainty that when you fill even AI-95 you will get it and not AI-80
. There are quite a lot of people who like to unload fuel. It’s not worth even thinking about AI-98; this gasoline is used for forced engines (see the article “For which cars is it better to use 98 gasoline”).
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.
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.
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.
But, if there is no high-quality fuel within reach that meets state standards, then you will need to focus solely on your own impressions.
Try refueling with one brand of gasoline, and then listen to the engine. If it remains smooth and does not arouse suspicion, then such fuel, albeit with caution, can be used. But, if the engine begins to make extraneous noise and operate intermittently, then this should be the first signal that this fuel must be drained immediately so as not to damage the car

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.
Which gasoline is better to fill in the Lada Granta: 92 or 95?
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 type 95 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 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.
The question “Which gasoline to choose 92 or 95” worries almost every car enthusiast. AvtoVAZ recommends using AI 95 gasoline on all Lada Granta engines.
However, many owners actively use cheaper AI 92 fuel. A minority spare no expense and fill the tank with AI 98 or AI 98 G-drive. So what kind of gasoline is better to fill in?
Quite a lot of research has been done on the topic “Which gasoline is better.” For example, the Autoreview website testing Renault Sandero and Hyundai Solaris cars on AI 92 and AI 95 gasoline came to the conclusion that the Renault Sandero on AI 95 accelerates better and is more economical than its competitor in the Hyundai Solaris test. It turns out that the efficiency and dynamics of a car running on different fuels directly depends on the type of engine.
Conducting a survey among owners of the tenth family of VAZs, it turned out that the majority of drivers noticed a slight increase in dynamics in comparison with the AI 92 on the AI 95. In addition, a car with AI-95 is slightly more economical than with AI 92.
Other sources, studying gasoline with different octane numbers, claim that compared to AI 92, AI 95 will not increase power by much, only by 0.1 hp. They say that a reduced octane number of gasoline will negatively affect engine performance, which in the future may result in a major engine overhaul.
Let us remind you that the fuel consumption of the Lada Granta depends not only on the quality of gasoline. What kind of gasoline do you recommend to fill in the Lada Granta?
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.
