Which Cars Cannot Use Ethanol Gasoline?
2 Answers
Older cars and poorly maintained vehicles should not use ethanol gasoline. Precautions for using ethanol gasoline include: 1. Clean the vehicle's interior before first use; 2. During cleaning, ensure complete removal of impurities from the fuel tank and fuel system, and drain any accumulated water at the bottom of the tank; 3. Prevent excessive moisture in the engine; 4. In summer, avoid filling the tank too full, leaving some space for fuel expansion and vaporization; 5. Ethanol gasoline can affect rubber components; 6. Choose ethanol gasoline based on the engine's compression ratio. Ethanol gasoline is an alternative fuel made by blending fuel ethanol, processed from grains and various plant fibers, with regular gasoline in a specific ratio.
I remember when I drove that 2004 Santana 3000, I once filled it with ethanol-blended gasoline and the engine shook like a sieve. The mechanic said older cars' rubber fuel lines and gaskets are prone to corrosion and cracking from ethanol, and the fuel pump can easily get clogged. Nowadays, you gotta be careful with cars over ten years old, especially those carburetor-equipped relics. Before refueling, it's best to check the manual - if it says "recommended to use unleaded gasoline," don't randomly mix in other types. Last time I saw someone driving an old Crown, their fuel system got clogged after using ethanol gasoline, costing over 800 just for cleaning. Actually, unleaded gasoline is quite easy to find at regular gas stations now, so owners of classic cars shouldn't risk damage just to save a few bucks.
