What is the difference between gasoline types?

[OGideon]

98-octane, 95-octane, and 92-octane gasoline differ in the following aspects: Different quality levels: 98-octane gasoline has a higher octane rating, while 95 and 92-octane gasoline have lower octane ratings. Higher octane fuel provides better anti-knock performance, resulting in smoother engine operation. Different fuel consumption: 98-octane gasoline has lower fuel consumption, while 95 and 92-octane gasoline have higher fuel consumption. The higher the gasoline grade (i.e., 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 based on their engine's compression ratio. Vehicles with higher compression ratios should use higher-grade gasoline to ensure strong power output and lower costs while preventing engine knocking.
