Can a car that uses 92-octane gasoline be filled with 95-octane fuel?
1 Answers
92-octane cars should not be filled with 95-octane fuel. Long-term use may affect the lifespan of the vehicle's ignition system, fuel injectors, and spark plugs, reduce fuel quality, and accelerate the need for major repairs. The recommended fuel grade is usually indicated on the inside of the fuel tank cap and in the vehicle's maintenance manual. Car owners should use the fuel grade suitable for their vehicle. Whether it's 92 or 95 octane, the number represents the gasoline's anti-knock properties, not its quality. A higher octane number indicates better anti-knock performance, but it does not mean the fuel is of better quality, contrary to what some car owners might think.
