Can 95 and 92 gasoline be mixed?
2 Answers
95 and 92 gasoline cannot be mixed. The following are the characteristics of gasoline: 1. Volatility: In the engine cylinder, it quickly vaporizes 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: 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. Additional information: The reason why different grades of gasoline cannot be mixed is that it affects the normal operation of the engine, causing car noise, weak driving, and engine damage. Gasoline is a volatile, flammable hydrocarbon mixture liquid distilled or cracked from petroleum and can be used as fuel.
I've been driving for over 30 years and often encounter similar issues, such as only being able to get 92-octane fuel at rural gas stations when my car requires 95-octane. Occasionally mixing them once in a while isn't a big problem—the engine runs fine and won't break down immediately. However, in the long run, mixing gasoline with different octane ratings can affect the engine's combustion efficiency. 95-octane fuel has better anti-knock properties, while 92-octane is inferior. Mixing them can lead to uneven fuel quality, potentially causing knocking—abnormal engine vibrations and noises—and over time, it may damage pistons or spark plugs. It's advisable to strictly follow the fuel grade recommended in your car's manual: if it calls for 95-octane, use 95-octane, avoiding temporary compromises. If you've already mixed fuels, don't worry too much—just switch back to the correct grade and run a few tanks to readjust. In short, make it a habit to check the manual—don't cut corners to save small money at the risk of bigger losses.
