Which gasoline to choose AI92 or AI95? This question worries every car owner. If we talk about AVTOVAZ’s new product, the Lada Vesta, it is worth noting that the manufacturer recommends using AI95 gasoline. To save money, many people start using cheaper AI92 fuel. And some, on the contrary, spare no expense and fill the tank with AI98 or AI 98G-drive..
In the operating manual Lada Vesta manufacturer
indicated that only unleaded gasoline “Premium Euro-95 GOST R 51866” or “AI-95-K5 GOST 32513-20013” is allowed for use. If necessary, it is allowed to use gasoline with an octane number of at least 92.

According to fuel requirements, the plant allows Vesta to be filled with unleaded gasoline, the octane number of which is at least 92, class 5. In principle, it is not currently sold at other gas stations. However, mechanics recommend filling in 95-grade gasoline and only at branded gas stations - at 92, VAZ engines are prone to detonation. This, by the way, is confirmed by the manual, which recommends using 95. As for 98 gasoline, this is unjustified and leads to unnecessary waste of money.
During winter operation, you can use an additive such as a fuel dryer; all other additives are unlikely to provide anything useful.
What the independent examination showed
Independent experts analyzed fuel from Rosneft Pulsar. As a result, it was found that all the detergent elements are already present in regular gasoline. And the new gasoline will not be able to increase power, like other innovations from similar companies. The difference between Pulsar is its detergent additives, not its high octane number.
Gas or gasoline - which is better to drive?
The new Pulsar may even cause engine damage if it contains excessive amounts of additives. If used for a long time, this will lead to costly repairs. The use of Pulsar in engines that are designed for fuel with a low octane number, additives will only reduce power.

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.

if the passport indicates 95, then pour 95.92, you can only pour unleaded, the additives used in our country kill the catalyst, even if you pour unleaded 92, then the difference in price will be eaten up by increased consumption compared to 95, the only alternative (so far known) is e92 + alcohol 96% in a ratio of 10/1.
who wants to kill the injectors, pour acetone into gasoline
Now I know, my thanks to everyone for participating
A little acetone was added to the fifth gasoline, and this became a pulsar. Buy a half-liter bottle of acetone and add 300 grams to a full tank and you’ll get “pulsar”, “ecto” and other crap.
When the 12th was made, they did this with 92. For 20 liters, 0.5 acetone.
do you have a grant carburetor?
I also heard a lot about the cleaning properties of the pulsar, but I decided to test them for myself. A year ago I bought a car with a mileage of 82 thousand, it stood at the former owner’s house for half a year under the entrance, and in the end, half of it ended. I changed the parts, so this is what I mean: after the purchase, he (the former owner) said that it only ran 95, although the 1.5 engine was designed for 92. The engine was not killed, it did not consume oil, but it completely refused to go more than 100. I live in the Moscow region and go to work via Minka, so I started refueling at TNK 95 Pulsar. I drove it like this until almost spring and the engine began to come to life. But here’s what’s also noteworthy: I started turning the engine for at least 3.5 thousand. In the summer, when I removed the fuel rail with injectors to clean the carbon deposits, the carbon deposits were minimal (the mileage by that time was 125 thousand). So, for prevention, you need not only to fill in “cleaning” fuel, but also to let the engine spin (at 4 thousand, the valve plates and the valves themselves rotate, carbon deposits are cleaned off, and wear becomes uniform). And I saw this concentrate (which makes a “pulsar” out of 95 95) in a friend’s garage, I even suggested pouring it into the tank
Rosneft recently began producing a new fuel - Pulsar gasoline. But car enthusiasts do not know how this innovation differs from others. Gasoline Pulsar - what is it? Let's figure it out together. There are few differences between it and other fuels. This is a common advertisement for drivers to pay more money, but there is no particular impact on driving performance. Other gas stations do similar tricks; reviews of Pulsar gasoline can be found on the Internet, and most of them are not very good.
Which gasoline drives the Lada Granta better - 92 or 95
Most motorists agree that speed and dynamic performance, as well as uniformity of operation, are better with fuel recommended by the manufacturer. Nobody said that the AI-95 is worse to drive. Some argue that there is no difference. Most likely, they prefer a calm driving style, so the dynamics are not very noticeable.

Is it worth filling in 92nd gasoline?
Proponents of cheap fuel often refer to a knock sensor, which will save you from a destructive blast wave. Having perceived its signal, the machine will adjust the ignition timing and the composition of the working mixture.
Reviews of Pulsar Gasoline from Rosneft
To really understand the differences between Pulsar gasoline, you need to read reviews from car owners. The price of Pulsar is about 1 ruble more than usual. Many people say that there is no noticeable increase in power, and there is no increase in mileage at all. There is no way to immediately check the cleaning properties; you need to disassemble the engine.
Why doesn't AvtoVAZ make automatic transmissions?
Although some drivers still try to deceive themselves and say that the engine has become softer. Others complain that starting has become more difficult.

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
What makes Pulsar different?
The short answer is that there are no differences, except perhaps in cost and a hit on the pockets of ordinary people. If you refuel Pulsar 92 and 95, write your opinion in the comments about its quality and price.
Recently, Rosneft introduced another new product - Pulsar 95 gasoline. But few people know how it differs from other fuels. Many car enthusiasts ask: “Gasoline Pulsar 92, what is it?” Our specialists decided to bring to people the information that they could find. Rosneft Pulsar gasoline is essentially not much different from other types of fuel.
There are similar advertising moves at other gas stations. For example, Gazpromneft has G-Drive gasoline, Lukoil has Ecto Plus, and so on. Pulsar gasoline does not yet have numerous reviews, but still this fuel has them, like any fuel and lubricants.
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.

An experienced driver knows what kind of gasoline to fill by monitoring the reaction of his car to different types of fuel. Properly selected gasoline plays an important role in maintaining the performance and mechanisms of the Lada Granta car. from hundreds of similar proposals - a real art that the driver will master only with time.
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.
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).
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 can happen to the engine if you fill it with the wrong fuel?
In fact, the manufacturer requires the use of only 95 gasoline for the most modest power plants - for 11186, but even for 11183-50 the use of 92 gasoline is not allowed, even as the maximum permissible . However, after pouring this fuel into the tank of their cars, many owners did not notice any differences in the operation of the engines.
One of the owners wrote that no changes occurred, except that detonation appeared. Another said that he examined the inside of the cylinder using an endoscope. This is a device that allows you to look into hard-to-reach places using a flexible or rigid rod. He said he didn't notice any wear on the cylinder walls.
