What gasoline to fill? Which gasoline is better to fill in the tank of the Lada Grant car What gasoline is better to drive the Grant
There is an opinion among the owners of domestic cars that they can refuel their vehicles with almost any fuel that is on the market. This statement dates back to the times when, apart from the "VAZ classics", nothing more modern could be found on the roads.
Only 95th gasoline?
Modern VAZ cars are equipped with which require a good attitude and high-quality care. This also applies to the brand of fuel that is filled into the tank.
According to the official documentation of Lada Granta, this car must consume only A-95 gasoline.
Can I refuel with A-92 gasoline?
There is such a concept as the octane number, which is determined in the numerical expression of the name of the fuel. If it is recommended to use 95 gasoline for the car in question, then there are reasons for this.
The fact is that an engine designed for A-95 gasoline can start working with any type of fuel. He won't do octane tests. Instead, in simple terms, it will treat any gasoline as if it were an A-95, compressing it accordingly.
And, given that the A-92 fuel has an octane number of three units less, then the degree of its possible compression 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 indicators of the combustion chamber are somewhat reduced.
Try to refuel at large chain gas stations.
If you fill in high-quality 92nd gasoline, then this is the main reason for those who like to refuel with gasoline with a lower octane number.
But, in the case of a proper technical condition, as well as with a new car, it will compress the working mixture to the maximum. And this is what gasoline with a lower grade is not designed for. So, if you do not want to hear the sounds of detonation, as well as eliminate the premature wear of car parts in the near future, then you should listen to the recommendations of the manufacturers, and "feed" the car exactly what is written in the instruction manual.
Video of a trial measurement of the present octane number of 92 gasoline
The video below is the process of measuring the octane number of gasoline, which was bought at regular gas stations in Novosibirsk. Only one probe showed the presence of really 92 gasoline.
And in the operating instructions for Lada Grant, gasoline is specified at least 95.
Simply put, any lower grade fuel will result in unintended knocking and. They are very small localized explosions that harm the condition of the cylinder and, to some extent, the piston. Moreover, all this can lead to increased wear and, most importantly,. So any attempt to save on cheaper gasoline will be doomed to failure.
How then to be with "older" gasoline?
Let's refuel with 98th?
Considering the above information, you might think that it would then be advisable to fill the car with gasoline with a higher octane number. For example, it can be A-98, which is the standard for many modern foreign-made cars.
But, here again you will have to upset, 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 exactly to the same level. And the potential of this fuel can be unlocked only when its compression force is higher, for which the Lada Grant engine is not designed.
The result of refueling with 98th gasoline will be the inability to use its properties to the maximum, and you will simply lose your money on the difference in the cost of gasoline of different brands.
Features of the national gas station
But, all this is theory. The fact is that the fuel situation in our country is not as rosy as one might expect. Often, the required octane number in the sold fuel is achieved by using special chemicals called "additives" (as in the video above). Thus, the chemical analysis will show the correspondence of this number to the brand, while the car may not want to work with this gasoline fully. In this case, you have to.
And the majority of domestic oil refineries do not have equipment that could process oil into gasoline of grades higher than A-92. It is for this reason that "among the people" there is an opinion that there is no difference in principle between brands with an octane number greater than 92.
But the cost of gasoline will vary significantly. In addition, the savings on the "right" fuel are not so high in terms of fuel consumption, which does not cover additional material costs. The only exception is the urban traffic cycle, where trips are made mainly in low gears and, often, high speeds of the power unit.
However, this is the opinion of people, but not car experts. And misuse is rarely associated with one's own carelessness. Instead, complaints about the build quality of the machine itself begin to arise.
Conclusions and opinions of the owners of Lada Grant
So what kind of fuel should you choose for Lada Grant engines?
The answer here will be very simple. If you have a gas station in your city that guarantees the quality of the gasoline that it sells, then it costs only 95 gasoline to buy. In addition, it will not be superfluous to monitor the compression at least once per fifty thousand kilometers. This will allow you to find out about the problems in time, if any, and immediately fix them. In this way, the car will be able to constantly use fuel to the maximum.
But, if there is no high-quality fuel within reach that would meet state standards, then you will need to focus exclusively on your own impressions.
Try to fill up with one brand of gasoline, then listen to the engine. If it remains smooth and not suspicious, then such fuel, albeit with caution, can be used. But, if, then this should be the first signal that this fuel must be drained immediately so as not to damage the car.
Often the question arises, what gasoline should be poured into Lada Granta? Sometimes it happens that even on the eve of buying this domestic car, thoughts about the brand of gasoline come to mind. In fact, it is, you cannot immediately figure out what to fill in the tank. Standard fluctuations occur between AI-92 and AI-95. Naturally, anyone is trying to save money on every little thing, and here it is not a trifle, but, so to speak, the main expense item is fuel.
In this regard, many prefer the AI-92, it seems that the price difference per liter with the AI-95 is insignificant, and with constant refueling it already starts to save something. If you come to a car service or somewhere else, to a specialist, and ask what you need to pour into the Grants tank, you will be almost 100% answered: you need to pour in accordance with the recommendations of the manufacturer. So, then the answer to this question is hidden in the instruction manual, which is familiar to everyone.
What does the instruction manual say?
What gasoline do you need to fill in Lada Granta? Open the operation manual in Appendix 1. We look at the text: the brand of the recommended gasoline - "Premium 95" or "Premium Euro 5" and two references to GOSTs. Why such a recommendation-limiting fuel proposal?
Let's see some points related to this limitation. The first note is the requirement for the required flammability at low temperatures.
It follows from this that gasoline must be of the required evaporative class. At the same time, this requirement is taken into account in different regions of the country, and the vaporization classes of gasoline, depending on the location, differ from each other. The second obstacle to using lower octane gasoline is the presence of metallic and organic particles in it, which act as antiknock agents. These particles contain lead, cadmium, manganese, iron and other metals.
High-octane gasoline is characterized by the introduction of various additives. These additives save from carbon deposits, corrosion damage, and various deposits. However, only the fuel manufacturer can add these additives. Naturally, you can do it yourself, but this is not recommended (the proportion may not be correct).
Drivers opinion
(banner_content) If you look at the reviews of the car owners Grants, then there is a complete mess. Some firmly claim that they fill AI-92 and rides fine without any problems. However, at the same time, additional detonation in the combustion chamber is noted. The latter assure 100% that it is necessary to fill in AI-95, so a slight decrease in fuel consumption is observed.And a third group has also formed, which pour 50 to 50 AI-92 and AI-95, and get in the tank at all, don't understand what. Such mixing from the point of banal logic seems to be understandable: the reduction of detonation and, but still it is not worth mixing.
Drivers who purposefully pour AI-92 do not feel significant differences in the dynamics of the car, engine operation and fuel consumption. The only thing that this replacement of the recommended fuel can clearly affect is.

Conclusion
Based on all of the above, we can conclude that it is best to fill in the recommended AI-95 in Lada Granta. Thus, we answered the question: what kind of gasoline you need to fill in Lada Granta. It is not worth experimenting and diluting two types of gasoline, firstly, it is inconvenient, and secondly, it is not clear what the consequences are.
Very often, car owners ask themselves what kind of gasoline to pour into Grant: 92 or 95. Sometimes, even before buying a car of domestic production, a motorist asks the question of what brand of gasoline to fill in his future car.
In reality, it is very difficult to know which gasoline will suit a particular 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 every month you have to spend a large percentage of your salary.
Based on this, most motorists choose AI-92. If we compare the price for one liter of AI-92 and AI-95, the difference will seem insignificant, but if we multiply the price for one liter by the number of liters of gasoline that is consumed within a month, the difference is significant.
If you visit a car service and ask a question about what gasoline is suitable for Lada Grants, you will receive an answer that it is necessary to refuel the car according to the recommendations of the company that produces this brand of car.
How does the car manual answer this question?
So, in order to answer the question whether it is possible to fill in 92 gasoline in the Grant, which worries many motorists, you should open the instructions on Appendix 1, which says that the recommended gasoline is "Premium 95" or "Premium Euro 5". Why are there such strict restrictions on gasoline in the instructions?
Let's figure it out. The first note states that it is necessary to provide the necessary flammability at low temperatures.
From this it follows that the fuel must be selected in a certain class of volatility. In different regions of the Russian Federation, this requirement is adhered to in different ways, and the classes of fuel volatility differ among themselves, based on location.
The second obstacle to the use of low-octane gasoline is various metal and organic particles, which are antiknock agents and are contained in gasoline. In the particles, you can observe the presence of lead, cadmium, manganese, iron and other metals.
Various additives are introduced into high-octane gasoline to prevent the appearance of soot, various deposits and corrosion. But these substances can be included in the composition of gasoline only 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 the drivers think about this?
There is a third group of car owners who fill the tank with gasoline of both brands, which is why the result is not very good. Drivers mix two types of gasoline in order to reduce knock and average gasoline consumption, but experts do not recommend mixing different types of gasoline.
Car owners who buy AI-92 do not see a significant difference in car dynamics, engine performance and gas mileage. If you replace the fuel recommended in the instructions for use with AI-92, then the only difference is the effect on the fuel system.
Can Grant 92 be refueled with gasoline?
Other motorists claim that they do not see any difference between using AI-92 and AI-95, and the engine in both cases will work almost the same. But everyone knows that the use of 92 gasoline leads to contamination of the engine system and spark plugs.
But, not taking this fact into account, many Russian motorists advise pouring AI-92 Grant into the Lada. Let's see if it is possible to refuel the Lada Grant 92 with gasoline.
Many oil refineries located on the territory of Russia do not have the technologies and equipment that can produce high quality 95-A gasoline.
Therefore, in order to create 95th gasoline, specialized additives are used that gasoline contains. The more such additives are contained in gasoline, the more negatively the effect of the use of such gasoline on the operation of the engine and the entire car system will be.
Well-made pure gasoline 92-A is much more suitable for any car, including the Lada Grants. On the territory of the Russian Federation, there are still several factories that produce high-quality gasoline up to 98th.
Most motorists advise you to familiarize yourself with the information about the gas stations that are in your city in order to understand which grade of gasoline to buy. You should find out where these gas stations get fuel, as well as who makes 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 poor quality fuel.
So, gasoline 92-A has the following features:
Leads to contamination of the engine system and spark plug;
Has a low cost;
Does not negatively affect vehicle dynamics;
Does not affect engine performance.
Can 92-A be used for turbocharged engine systems?
Good gasoline is gasoline from the manufacturer Lukoil. 92-A and 95-A are quality products when compared to other gasoline grades. By using these grades of gasoline, the driver uses less fuel and there is also little effect on the spark plugs.
Many car owners believe that even for turbocharged engine systems, both the 95-A and 92-A will work. But experts recommend using 95th gasoline for engines that contain additional devices. Therefore, when deciding whether it is possible to refuel the Lada Grant 92 with gasoline, if it contains a turbocharged engine, it is better to stop at 95-A.

I must say right away that before buying Lada Grants, I had quite a lot of different cars from Avtovaz, ranging from the classic VAZ 2106 and ending with the Priora with a 16, 16-valve engine. So, all cars had to go on almost any gasoline, starting from the cheapest AI-76 (it was still there), AI-80, 92 and 95th. And I would like to tell you a little about my impressions and operating experience with fuel with different octane numbers.
Usually, I fill in 95, because I think that the Grants manufacturer does not recommend this type of gasoline for nothing. Of course, I tried to fill it in at a cheaper rate, 92 and I have to use it quite often, since there are no good gas stations in the village. Below I will tell you a little about all types in more detail and share my impressions:
AI-95
Of course, fuel consumption with an ethical octane rating is the lowest. If you take your time and go slowly no more than 90-100 km / h, then on the highway it is quite possible to keep within 5.5 liters, and sometimes even less is obtained. The dynamics are excellent, what else to say, it starts up perfectly and the engine runs flawlessly. Of course, the quality of this gasoline differs at different gas stations, but in most cases it comes across quite decent!AI-92
As for this gasoline, sometimes you don't even notice the difference in engine operation, and most likely this is achieved thanks to the knock sensor, which they began to install on all VAZ injection engines, including Grant. But the consumption increases slightly, at the same speed by about 0.5 liters. So even if you saved a couple of rubles per liter, this does not mean at all that in the end you were the winner. In fact, on the contrary, you will have to spend a little more money at the gas station, pouring 92 gasoline.AI-76 and 80
To be honest, I even had to operate all my cars on such a badag. Of course, I don't want to talk about fuel consumption, since the readings of the on-board computer are frightening with an increase at once by 1 or even more liters per hundred kilometers. The engine starts up normally, it also works almost indistinguishable from more expensive gasoline, but this is again the merit of the knock sensor. My opinion is that it is better not to exploit Grant on such a slag, but to overpay for better quality gasoline with a high octane number. So you can really save money, as it turned out in the course of personal experience, and the motor will work trouble-free much longer!Share your experience, what are your observations about the reaction of the engine to an increase or decrease in octane number.

Look at the table - all presented cars are equipped with engines produced by the Volga Automobile Plant. The source of the given fuel data is the latest operating manuals.
There are many questions. For example, why does the 16-valve K4M engine developed by the alliance under the hood of Lada Largus require AI-95, while in Almera, Logan and Sandero it can work on AI-91? Moreover, Renault even allows short-term operation on gasoline with an octane rating of 87 according to the research method. There is no such variety in Russia, but a low-quality 92nd can get into the tank, with which the motor can at least cope with it.
The situation with domestically developed motors is no better. Not so long ago, VAZ had a unified technical policy - it was allowed to use "only unleaded gasoline with an octane rating of at least 95". This position of engine developers is justified. It is difficult to accept, but understandable. Indeed, the best indicators of efficiency, environmental friendliness and throttle response are achieved with high-octane fuel. Plus the manufacturer's insurance against low-quality fuel in the regions. The electronic control system will cope within reason with the lowered octane number. Read it - it's a mess, if, instead of the 95th, the crooks flood the 92nd - nothing will happen to the engine. Officially permit the 92nd, and instead of it, a mixture of 92 and 76 can get into the tank, and this is already fraught.
But new generation cars have appeared, and what do we see? For Vesta and XRAY with a VAZ-21129 engine, AI-92 is allowed, and for similar engines on Priora, Kalina and Grant under the VAZ-21127 index, only AI-95 is allowed. Or, say, an eight-valve VAZ-11189 for Largus officially swallows the 92nd, and give the same Kalina VAZ-11186 motor only the 95th. With the wording, too, leapfrog: for technically identical Lada and Datsun, in one case it is allowed, in the other - it is recommended.
Moreover, the picture is curious - more expensive cars are allowed cheaper gasoline, and the most popular cars are more expensive. Nonsense? Certainly!
Does anyone seriously believe that the owners of inexpensive domestically produced cars blindly follow the instructions? Okay, more or less fresh 16-valve engines: here you can hide behind an argument - they were designed for high-octane fuel. But how to convince the owners that the dense engines of the classic family for Lada 4x4 and Chevrolet Niva cannot live without the 95th, and the eight-valve descendants of the reliable "eight" engine will start to break down on the 92nd? But the consumer understands very well - with an average annual mileage of 12 thousand km and a difference in the price of fuel of three rubles per liter, at the 95th it will fly into the exhaust pipe at least three thousand rubles more.
