Frequently asked question: What kind of gasoline can I fill in the Lada Granta?

A comprehensive answer about the octane number of the gasoline used should be contained in the vehicle operating instructions. But within the AVTOVAZ and Renault-Nissan group there is no single approach - different types of fuel are prescribed for the same engine installed on different models.

LADA > Kalina

Nissan > Almera

Renault > Logan

Renault > Sandero

Look at the table - all presented cars are equipped with engines produced by the Volzhsky Automobile Plant. The source of the fuel data given 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 the Lada Largus require an AI-95, but in Almere, Logan and Sandero it can work on an 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 grade in Russia, but low-quality 92nd may end up in the tank, which the engine can cope with at the very least.

The situation is no better with domestically developed engines. Not so long ago, VAZ had a unified technical policy - it was allowed to use “only unleaded gasoline with an octane number of at least 95.” This position of engine developers is justified. It's hard to accept, but understandable. Indeed, the best indicators of efficiency, environmental friendliness and acceleration are achieved with high-octane fuel. Plus the manufacturer’s insurance against low-quality fuel in the regions. The electronic control system will cope with the reduced octane number within reason. Read - it's a re-grade, if instead of 95 the swindlers fill in 92 - nothing will happen to the engine. If 92 is officially allowed, a mixture of 92 and 76 may end up in the tank instead, and this is already fraught.

But a new generation of cars has appeared, and what do we see? For Vesta and XRAY with a VAZ-21129 engine, AI-92 is allowed, and similar engines on Priora, Kalina and Grant under the VAZ-21127 symbol are allowed only AI-95. Or, let’s say, the eight-valve VAZ-11189 for Largus officially swallows the 92nd, but give the same Kalina VAZ-11186 engine only the 95th. The wording is also a mess: for technically identical Lada and Datsun, in one case it is allowed, in the other it is recommended.

A few words about American and turbocharged engines

I was also bombarded with the following questions: “I bought a car imported from the USA, it says that you need to use AKI 91 gasoline. What is this, and what kind of fuel should I choose?”

The US market has slightly different standards; their classification is not like ours (that is, “research”). The abbreviation AKI means a conditional, average designation of two indices ((“research” + “motor”)/2).

If we bring it closer to our standards, we get something like this:

AKI87 = AI92

AKI89-91 = AI95

AKI93 = AI98

I would also like to note the turbocharged options; in the last article I said that it is recommended to use at least “95” in them.

Let's think logically, why 95 and 98? Turbocharged engines use much larger volumes of air and fuel, the mixture in them must be richer, and from the points above we understood what ENRICHED fuel is, it gives us more octane. Think for yourself - WHY BUY A TURBO, AND FURTHER FEED IT WITH LEAN MICHES, it’s just not designed for that! The amount of air must strictly correspond to the caloric content of the fuel.

It is also worth noting that when using the “92”, as many manufacturers indicate, the “required temperature regime” may be violated, which may lead to the failure of some components, in particular the “turbine” itself.

Therefore, in TURBO, only what the doctor ordered, otherwise it is fraught with repairs.

Now there is a video version of the article, VERY USEFUL.

I’ll end here, I think it was useful, sincerely YOUR AUTOBLOGGER.

Conclusions and opinions of Lada Granta owners

So what fuel should you choose for Lada Grant 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.

I have a new car, the mileage is only 20,000 km, according to the instructions I always use 95, and apparently it’s not in vain that I don’t experiment with 92.

I never skimp on gas. The difference in cost is minimal and is paid off by lower fuel consumption if you fill up 95m. As a result, you travel the same number of kilometers for the same amount, but only with higher quality gasoline. I don’t see the point of filling in 92

I drive 95. The difference from 92 is insignificant. For almost the same money I drive the same number of kilometers, and the engine pulls great.

Why experiment? This is some kind of strange saving - saving a penny and then losing a ruble later. My opinion is that if you bought a car that, according to the instructions, requires '95 or '98 gasoline, then fill it there...

I would be sorry to fill in 95 gasoline in accordance with the grant. The Russian auto industry accepts 76 gasoline without problems.

Have you tried filling Grant 76 with gasoline? It is no longer sold even at gas stations according to EURO standards.

when you are 80 years old, don’t forget to tell yourself “I feel sorry for spending money on expensive medicines, I live in Russia.”

For me, it’s better to fill in 95. In general, it also seems to me that the difference between 95 and 92 is barely visible. But 95 is still preferable.

How “critical” will it be in practice if a couple of times, due to the need or impossibility of finding 95, fill in 92?

It’s okay if you fill up with 92nd grade gasoline instead of 95—no.

Of course, when operating a car, you must follow the recommendations specified in the documents accompanying it. If it is written that the engine should consume 95 AI, then preference should be given to it. There’s just one thing: 95 AI is often of poor quality, which happens much less often with 92.

Of course, I would like to agree with the opinion that it is better to pour 95 than 92, but now it is difficult to find a good 95. Therefore, it makes no difference which one to pour, the main thing is at a proven gas station, otherwise you can fill it with such 95 that it would be better not to fill up at all. My Grantochka runs at 95 with one fill-up.

I think it’s worth filling up with 95, but only at trusted gas stations, and plus 95 is enough for a longer distance.

Of course, 95, from personal experience, I can say that I tried 92 and it turns out more expensive. And the car behaves worse. 15 liters was enough for me to understand everything, so definitely 95

I have always refueled with 92 fuel, when at 95 I can say that the engine power is actually slightly higher, so the consumption is slightly reduced. This is a double-edged sword, either you save money or you drive faster.

Absolutely, in the technical specifications for the Lada Vesta and Lada Hray with the same 106 hp engine. it is written: gasoline is not lower than 92, and in Grant it is not lower than 95. 95 may be worse than 92, it may contain more anti-knock additives.

It seems that the firmware on Grant and West is different. On Vesta, the engine was slightly strangled, but adapted to 92 gasoline. Everyone from the West copies

How I bought Grant I pour 92 gasoline Tatneft and Rosneft, mileage from 3 km to today 1744 km consumption 6.65

Now the mileage is 6500 km, highway consumption at a speed of no more than 100 km/h is 5.3…….5.7 liters of AI-92 gasoline Tatneft or Rosneft (trip to the south with a mileage of about 4000 km) engine 11186, last trip on the highway 284 km with an average consumption of 5.4 liters

Have you ever seen the new Grant? What kind of domestic auto industry are you talking about, Renault Nissan Bosch etc. You're so stuck in the past

Now the mileage is 8500 km, the average city-highway consumption (I reset it to zero after every hundred miles driven) is 6.2……6.8 liters, I haven’t gone any higher, city/highway 50/50. I fill up the AI-92 Rosneft or Tatneft almost free of charge.

Consumption is 95 less than 92, but it’s not displayed on the BC, but in terms of kilometers it’s significantly higher, and it’s especially faster during acceleration, so 95

I fill up 95 from new and only Bashneft mileage is 50,000, no problems with starting even at very low temperatures, I haven’t even smelled 92, we even fill up service fours with 95

On grant, engine 21127 was filled with 95 after purchase. Two weeks after purchase, the engine stopped starting (in the summer). And if it starts, then until it warms up to 35 degrees, Troil. At the dealership where I bought the car (also an authorized service center) they told me to fill up with 92. Since then there have been no problems. In winter it started normally. It seems that in our area the quality of the fuel is more critical than the octane number.

gasoline 95, internal combustion engine 21127, on the highway 35 liters are enough for 750 km, speed 95-105, outside temperature + 16... + 24, two people with a full trunk. 4.66 l/100 km. Mileage 30,000 km. I’m very surprised that they are discussing savings, but say nothing about tire size.
