The fuel that the engine must burn is described in detail in the instructions for the car and only such fuel should be poured into the tank.

You will find in the owner's manuals of many vehicles that higher octane fuel can be used but will not improve engine performance. Considering the economic aspect / 98 gasoline is more expensive than 95 / it makes no sense to use more expensive fuel if it does not improve performance.

However, our fuel reality is different.

It is known from experience that most engines running on 98-octane gasoline are quieter and more dynamic. Therefore, when there are promotions at the stations and gasoline prices are equal, it is worth refueling with better gasoline.
