A car expert explained why it is stupid to refuel with AI-95 if the engine is for AI-92 – Rossiyskaya Gazeta

“Sometimes in Russia, fuel with a higher octane number is obtained from fuel with a lower octane number by adding various additives. That is, in fact, the basic composition is the same. However, most factories in Europe and some Russian manufacturers. receive it due to better distillation, that is, cleaning.

Modern cars usually have powerful engines. They have great acceleration and run efficiently on high-octane fuel: AI-95, AI-98. But if you regularly fill them with 92 grade gasoline, you will not only lose power, but also risk engine damage due to improper loads.

The process in the engine can be described like this: fuel enters the engine cylinders, then is compressed by the piston and ignited by the spark plug. The lower the octane rating of gasoline, the faster the combustion process begins; the larger it is, the more resistant the fuel is to ignition;

Now imagine that a modern, powerful engine is full of fuel, which ignites earlier than automotive engineers expected. Naturally, the engine will experience increased loads. This will cause premature engine wear and reduce engine life.

Exactly the opposite will happen with old engines that were installed, for example, in the domestic Lada 20-30 years ago. Imagine, a driver, hoping to improve engine performance, fills an old car with 98 or, worse yet, 100 of gasoline.

At the same time, we understand that an old car engine has a low compression ratio. You will experience enormous stress due to running on high octane fuel. Therefore, instead of efficiency, environmental friendliness and lower fuel consumption, the driver receives faster engine wear or, often, an impressive bill for the repair of the unit.

I advise you to fill in the fuel that is specified in the car instructions. Sometimes the recommended markings are duplicated on the back of the tank cap.

Car manufacturers always indicate a specific octane number or an increase allowed for refueling a specific car model. This is not done by chance; This particular engine is designed and engineered for certain characteristics of gasoline. Only when the recommendations are followed does the engine remain in better condition and run without interruptions,” highlighted the specialist.
