Should turbocharged cars use 92 or 95 octane gasoline?

[DelLilliana]

Whether a turbocharged car uses 92 or 95 octane gasoline is determined by the manufacturer's tuning and settings. Not all turbocharged engines require 95 octane gasoline, nor does a higher compression ratio necessarily mean 95 octane gasoline should be used. Gasoline is a volatile, flammable hydrocarbon mixture liquid distilled or cracked from petroleum, used as fuel. The characteristics of gasoline are: 1. Volatility: It quickly vaporizes in the engine cylinder and forms a uniform combustible mixture with air; 2. Stability: The ability to resist oxidation under normal temperature and liquid phase conditions is called stability; 3. Anti-knock property: Refers to the ability of gasoline to resist detonation combustion under various usage conditions; 4. Corrosiveness: Sulfur compounds in gasoline can cause corrosion to objects.
