Can 92 and 95 gasoline be mixed together?
4 Answers
92 and 95 gasoline cannot be mixed together. The effects of mixing them are: 1. Abnormal engine operation; 2. Increased vehicle noise; 3. Reduced driving power; 4. Engine damage. The characteristics of gasoline are: 1. Volatility: It rapidly vaporizes in the engine cylinder and forms a uniform combustible mixture with air; 2. Anti-knock property: Refers to the ability of gasoline to resist detonation combustion under various usage conditions; 3. Stability: The ability to resist oxidation under normal temperature and liquid phase conditions; 4. Corrosiveness: Sulfur compounds in gasoline can cause corrosion to objects. Gasoline is a volatile and flammable hydrocarbon mixture liquid obtained from petroleum through distillation, cracking, or pyrolysis, and can be used as fuel.
Last time I drove to the countryside, the fuel gauge light came on. The only gas available nearby was 92 octane, so I added some. After driving a few kilometers, the car started shaking a bit, and the engine sounded strange. I checked the manual and found that my car requires 95 octane. Mixing fuels can cause the octane rating to fall below standard, reducing anti-knock performance. Long-term use can lead to carbon buildup and accelerated wear. The mechanic said it's okay occasionally, but don't make a habit of mixing, especially for high-performance engines. It's best to get into the habit of checking the fuel cap or manual for recommended fuel. If you mix fuels, try to use it up quickly and switch back to the correct octane to avoid costly repairs.
As a family car owner, I always remind my family not to mix 92 and 95 gasoline. If the car requires 95, mixing fuels can easily cause knocking, damaging the engine and affecting safety. Once during a trip, I mixed a little and found that fuel consumption increased, making it not cost-effective. The 4S shop recommends sticking to one type; mixing is temporarily feasible but carries many risks, such as damaging the catalytic converter. Remember to check the label before refueling—use what is specified. Saving money is not as important as ensuring safety.
Simply put, it's best not to mix 92 and 95 gasoline. The octane ratings are different, and mixing them can cause unstable engine operation, increased fuel consumption, and even knocking if the car requires higher anti-knock properties. Occasionally using 95 in a car that requires 92 is fine but a waste of money. Sticking to the recommended grade is the safest option. Mixing occasionally in emergencies is acceptable, but don't make it a long-term practice.
