Car labeled to use 92 octane gasoline can use 95 octane. Gasoline is a volatile, flammable hydrocarbon mixture liquid distilled or cracked from petroleum. At room temperature, it appears as a colorless to light yellow mobile liquid, difficult to dissolve in water, and flammable. Gasoline grades are classified by octane rating, which represents the ratio of gasoline's anti-knock properties to those of standard gasoline. The higher the octane number, the stronger the anti-knock performance, but higher octane doesn't always mean better. The appropriate gasoline grade should be selected based on the engine's compression ratio. Mixing different grades of gasoline can lead to incomplete combustion, carbon deposits, and shortened engine lifespan.
