What Grade of Gasoline Should a Regular Family Sedan Use?

[SabrinaMarie]

Generally, family sedans can use 92-octane gasoline. The appropriate gasoline grade can be checked in the vehicle's user manual based on the specific model. Below is some relevant information: Gasoline: Gasoline is a type of fuel, appearing as a transparent liquid. In China, gasoline grades include 92, 95, 98, etc. Gasoline is insoluble in water and can be used not only for automobiles but also in aviation. It has properties such as volatility, stability, corrosiveness, and anti-knock quality. Octane Rating: Currently, most cars use either 92-octane or 95-octane gasoline. The difference in gasoline grades is due to variations in octane ratings. A higher octane rating results in greater kinetic energy from combustion, so vehicles with lower power output typically require lower-octane gasoline. Gasoline is stored in fuel tanks, which contain components like coolers. Regular maintenance of the fuel tank can help extend the lifespan of the gasoline.
