What is the difference between gasoline grades 92, 95, and 98?

[RicardoLee]

98, 95, and 92 gasoline differ in the following aspects: Different quality levels: 98 gasoline has a higher octane rating, while 95 and 92 gasoline have lower octane ratings. Gasoline with a higher octane rating has better anti-knock performance, and the engine runs more smoothly. Different fuel consumption: 98 gasoline has lower fuel consumption, while 95 and 92 gasoline have higher fuel consumption. The higher the gasoline grade, meaning the higher the octane content, the less likely it is to cause knocking, and the better the engine's anti-knock performance during combustion. Car owners should choose gasoline according to the engine's compression ratio. Vehicles with high compression ratios should use high-grade gasoline to ensure strong power output and low cost without engine knocking.
