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.

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.

Differences

But first, let's talk in a nutshell about the differences between these two most popular brands offered at gas stations. After all, many drivers, especially beginners, think that the 95 is of higher quality compared to the 92 and cannot harm the engine. But the opposite is true.

Higher gasolines are produced on the basis of 92nd

, by adding to it all sorts of additives that can increase the octane number. Therefore, 92 is cleaner than its counterparts, it turns out (although, according to experts, in the Russian expanses, especially in the outback, it is difficult to find fuel that is not created with the help of additives, even 92). But the same experts claim that due to the low octane, 92 and there are few additives, and it itself is cleaner.

By the way, adding these chemicals and bringing raw materials to rank 95 costs gas stations less than purchasing the same material from oil refineries. That's why so many people are doing body blows. Such a homemade 95 can be extremely dangerous for the engine, since the buyer does not know for certain what has been added to it!

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.

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

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?

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.
