Does Ethanol Gasoline Harm Cars?
2 Answers
Ethanol gasoline can harm cars due to the following reasons: 1. Ethanol, being alcohol, is corrosive to the car's fuel tank, fuel lines, and engine; 2. The recommended usage period for ethanol gasoline is 15 to 25 days, beyond which fuel separation may occur; 3. Ethanol has a low heat value, resulting in slower combustion and insufficient power output. The benefits of ethanol gasoline include: reducing and removing carbon deposits inside the engine, improving engine performance. As a new type of fuel made from fermented grains, ethanol is considered a green energy source. Using 10% ethanol as a new energy source helps reduce exhaust emissions and has a positive impact on environmental protection.
As an ordinary car owner who has been driving daily for many years, I was also hesitant when I first started using ethanol-blended gasoline, worried about it corroding components or affecting the engine. But after actually using it for five or six years, I haven’t encountered any issues. Nowadays, it’s quite common to find gasoline mixed with a bit of ethanol, available at gas stations everywhere. Modern car designs already take this into account, and an E10 blend is completely safe. My car is a 2015 model, and it starts up, accelerates normally, with stable fuel consumption. The key is to keep up with maintenance: I check the fuel system every 5,000 kilometers to ensure the fuel filter is clean and prevent moisture buildup. For older cars, like those from the 1980s, the rubber hoses might not hold up, so they’d need updating or avoiding high-ethanol blends. In short, ethanol-blended gasoline doesn’t harm your car. Driving with it for a few more years even benefits the planet—feels like a good deal. Use it with confidence, don’t over-worry about your car’s condition, but remember, maintenance is the golden rule.
