Which Cars Cannot Use Ethanol Gasoline?
2 Answers
Cars that cannot use ethanol gasoline include: 1. Older vehicles: The fuel system seals in older cars are only resistant to gasoline corrosion and cannot withstand ethanol, making them unsuitable for long-term use of ethanol gasoline; 2. Poorly maintained vehicles: For poorly maintained cars, ethanol gasoline may dissolve long-term deposits of gum-like substances in the fuel system and carry them into the cylinders, causing carbonization reactions under high temperatures, leading to new carbon deposits in areas such as fuel injectors, intake valves, exhaust valves, and even the catalytic converter. Ethanol gasoline is an alternative energy source formed by blending fuel ethanol, processed from grains and various plant fibers, with regular gasoline in a certain proportion. According to China's national standards, ethanol gasoline is a mixture composed of 90% regular gasoline and 10% fuel ethanol. Adding an appropriate amount of ethanol to gasoline as a vehicle fuel can save petroleum resources, reduce air pollution from vehicle emissions, and promote agricultural production.
I've been driving for years and know that some older cars really can't handle ethanol-blended gasoline. Take my 1990s Honda for example—once I accidentally added some E10 fuel, and within days the engine started making strange noises. Ethanol is highly corrosive and eats away at the rubber hoses and seals in older cars. Vintage cars are especially vulnerable, with most pre-1990s models unable to use it. Motorcycles shouldn't use it either, as ethanol absorbs moisture, leading to rust and fuel leaks in the lines over time. A friend's lawnmower in the garage broke down completely after using ethanol fuel. I recommend checking your vehicle's manual—if it specifies pure gasoline only, don't take the risk to avoid costly repairs.
