Can a car that uses 92-octane gasoline be filled with 95-octane gasoline?
1 Answers
A car that uses 92-octane gasoline should not be filled with 95-octane gasoline, as it can have the following effects: 1. Damage to the engine, spark plugs, and the car's ignition system; 2. Shorten the engine's service life. Gasoline is a volatile, flammable hydrocarbon mixture liquid obtained from petroleum through distillation or cracking. At room temperature, it appears as a colorless to pale yellow, easily flowing liquid that is difficult to dissolve in water and is highly flammable. Mixing different grades of gasoline can lead to incomplete combustion, resulting in carbon deposits and shortening the engine's lifespan. Gasoline grades are classified based on octane ratings, which represent the ratio of the gasoline's anti-knock properties to those of standard gasoline. Higher octane numbers indicate stronger anti-knock performance, but higher grades are not necessarily better. It is essential to choose the appropriate gasoline grade based on the engine's compression ratio.
