Can a car that uses 92-octane gasoline be filled with 95-octane gasoline? Yes, but it is not recommended. Different octane ratings of gasoline have different levels of octane values. The higher the fuel octane rating, the less prone the fuel is to detonation, making it suitable for engines with higher compression ratios. Conversely, engines with lower compression ratios require lower octane fuel. It is not the case that the higher the gasoline octane rating, the better for the car. The choice of gasoline octane should be based on the engine's compression ratio. If a car designed for 92-octane gasoline is filled with 95-octane, the high anti-knock advantage of 95-octane gasoline cannot be utilized, leading to delayed combustion and increased carbon deposits in the engine.
