Can a car that uses 95 octane gasoline be filled with 92 octane?

[Mackenzie]

A car that uses 95 octane gasoline should not be filled with 92 octane. 95 octane gasoline has a higher octane rating than 92 octane. Using 92 octane gasoline can cause knocking or pre-ignition, severely affecting the engine's performance and fuel efficiency, and in serious cases, it can damage the engine. The grade of gasoline is an indicator of its anti-knock properties, which is essentially unrelated to cleanliness, power, or calorific value. The higher the octane number, the stronger the gasoline's ability to resist engine knocking. The difference between 92 and 95 is that 95 is more resistant to knocking than 92. It is advisable not to mix different grades of gasoline. Short-term mixing will not cause significant harm to the car, but the hazards of long-term mixing should not be overlooked. Mixing different grades of gasoline over a long period will affect the lifespan of the car's ignition system, fuel injectors, and spark plugs, leading to earlier major repairs.
