Can 98 gasoline be mixed with 95?

[JaylaLynn]

It is acceptable to mix 98 gasoline with 95. Below are the relevant details about gasoline: 1. The difference between 98 and 95 gasoline: 98 gasoline contains 98% isooctane, while 95 gasoline contains 95% isooctane. This is the primary distinction between these two fuel grades. For fuel, the higher the proportion of isooctane, the better its anti-knock performance. 2. Gasoline of different grades should not be mixed: If a car requires 98 gasoline, occasionally using 95 gasoline once will not cause immediate issues, but prolonged mixing can damage the engine. When mixed fuels are used, the car may experience knocking during operation, which is more noticeable when the car is idling. Additionally, prolonged use of mixed fuels can lead to incomplete combustion, increasing engine carbon deposits.
