What kind of fuel should motor vehicles use?

[AthenaAnn]

Motor vehicles generally use No. 92 or No. 95 gasoline. Here are the specific details about refueling cars: 1. Gasoline grade explanation: Although higher-grade gasoline has better anti-knock performance and power, vehicles designed for lower grades should not blindly use higher-grade gasoline. Higher grades are more suitable for engines with larger compression ratios, while engines of cars using lower-grade gasoline usually have smaller compression ratios. Using higher-grade gasoline may increase engine knocking. 2. Avoid mixing different grades: Different grades of gasoline should not be mixed, such as mixing No. 98 and No. 95 gasoline. Long-term use may have certain impacts on the engine, and may even cause phenomena such as engine carbon deposits and increased fuel consumption.
