Can I Add 95 Octane Gasoline When 92 Octane Is Not Completely Used Up?

[ElleLynn]

92 gasoline not completely used up can add 95, but should not be mixed for a long time. The following is the relevant introduction about gasoline: Precautions for car refueling: The higher the octane number of gasoline, the better its anti-knock performance. When the air-fuel mixture is injected into the cylinder, the piston moves upward to compress the air-fuel mixture. When the pressure increases, the temperature rises. If the anti-knock performance of the gasoline is too low at this time, combustion will start before the spark plug ignites, resulting in detonation, commonly known as knocking. Knocking not only affects the engine's output but also causes damage to the engine. Choose gasoline octane number according to the vehicle model: 92 octane gasoline is suitable for ordinary cars with low technical content. 95 octane gasoline is suitable for the vast majority of cars. 95 octane gasoline is suitable for turbocharged and high-compression ratio models, and it is compatible with most vehicles.
