Should You Turn Off the Engine Before Opening the Fuel Tank When Refueling a Car?

[LeIsabelle]

When refueling a car, you should turn off the engine before opening the fuel tank. Here are some refueling precautions: 1. Use automotive gasoline only, as inappropriate fuel entering the fuel system may damage both the fuel system and the engine; 2. Do not use gasoline containing methanol or alcohol; 3. Avoid spilling fuel on painted surfaces to prevent paint damage; 4. If the fuel tank door is frozen and cannot be opened, gently push or tap the door to remove ice and open it; 5. Prevent excessive fuel pressure that could cause spraying; 6. Insert the fuel nozzle deep into the tank to avoid overflow or spillage, which could lead to fire or explosion; 7. Before opening the fuel filler cap or touching the fuel nozzle, touch the car body to discharge static electricity, and avoid re-entering the vehicle during refueling to prevent static buildup.
