The main reasons for high fuel consumption in a car are: 1. Poor driving habits of the driver; 2. Wear and tear of engine-related components; 3. Faulty oxygen sensor; 4. Low tire pressure or severe tire wear; 5. Incorrect fuel grade, clogged fuel lines, or improperly gapped spark plugs. Precautions for refueling include: 1. Use automotive gasoline; inappropriate fuel entering the fuel system may damage the fuel system and engine; 2. Do not use gasoline containing methanol or alcohol; 3. Avoid spilling fuel on the paint surface to prevent damage; 4. If the fuel door is frozen and cannot be opened, gently push or tap the fuel door to remove ice and open it; 5. Prevent excessive fuel pressure from causing spraying; 6. Insert the fuel nozzle deep into the fuel tank to avoid overflow or spillage, which could lead to fire and explosion.

Which Cars Cannot Use Ethanol Gasoline?

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.
