Can Ethanol E95 and 95 Gasoline Be Mixed?
2 Answers
Ethanol E95 and 95 gasoline cannot be mixed. The effects of mixing them are: 1. Shortening the service life of the car's ignition system, fuel injectors, and spark plugs; 2. Advancing the vehicle's major repair time; 3. Causing unstable power in the car; 4. Increasing exhaust pollution and harming the environment. The precautions for refueling are: 1. Choose to refuel when the temperature is relatively low; 2. If the car is not used for a long time or used infrequently, keep a small amount of fuel; 3. Do not refuel when the tanker truck is unloading fuel; 4. Turn off the engine when refueling a gasoline car; 5. Gasoline of different grades cannot be mixed. Long-term mixing of gasoline of different grades will affect the service life of the car's ignition system, fuel injectors, and spark plugs.
Once when I was out and the fuel gauge was nearly empty, the only gas station around had ethanol-blended E95. I reluctantly filled my tank, which normally takes regular 95-octane fuel. There were no noticeable issues while driving, and the power remained unchanged. Actually, mixing these two fuels short-term isn’t a big problem—both have a 95 octane rating, so no knocking occurs. However, ethanol-blended gasoline is slightly more corrosive and may accelerate the aging of rubber components in older cars’ fuel systems. Also, if there’s water in the tank, ethanol can separate more easily, so it’s best to burn through the mixed fuel quickly. My car usually runs on regular 95, and occasional mixed fill-ups haven’t caused any problems, but long-term mixed use is still not recommended.
