What to Do If You Filled Up with the Wrong Fuel?
2 Answers
Here are the solutions for filling up with the wrong fuel: High-grade car filled with low-grade fuel: If a high-grade gasoline car is filled with low-grade gasoline, it is recommended that the owner drain the wrong fuel or purchase related fuel additives to improve fuel quality and reduce the damage of low-grade fuel to the engine. Low-grade car filled with high-grade fuel: If a low-grade gasoline car is filled with high-grade gasoline, there is no problem, just remember not to make the same mistake next time when refueling. Diesel and gasoline mixed: If a gasoline car is filled with diesel or a diesel car is filled with gasoline, contact a car repair shop as soon as possible to clean the fuel tank and fuel system, and conduct a comprehensive inspection of the engine.
If you fill up with the wrong fuel, such as putting diesel in a gasoline car or vice versa, my strongest advice is to immediately avoid starting the engine. Starting the engine will allow the wrong fuel to enter the engine system, causing irreversible damage. I once personally experienced a situation where a friend accidentally filled his gasoline car with diesel. Fortunately, he didn't start the engine and directly called a tow truck to take it to a professional repair shop. Cleaning the fuel tank, fuel lines, and injectors cost over 2,000 yuan to fix; if the engine had been started, the repair costs could have reached tens of thousands or even resulted in engine failure. For prevention, always check the fuel pump label carefully before refueling to confirm whether it's gasoline or diesel. The color coding at gas stations (green for gasoline, black for diesel) is also helpful. Remember, stay calm, contact a tow truck or repair service promptly, and don't attempt to fix it yourself. Safety first—avoid driving and causing accidents.
