Should the engine be turned off when refueling a motor vehicle?

[DiBryce]

When refueling a motor vehicle, the engine should be turned off. The precautions for refueling are: 1. Use automotive gasoline, as 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 tank door is frozen and cannot be opened, gently push or tap the fuel tank door to remove the ice and open it; 5. To prevent excessive fuel pressure leading to spraying; 6. Insert the fuel nozzle deep into the fuel tank to avoid fuel overflow or splashing, which could cause fire and explosion; 7. Touch the vehicle body to discharge static electricity before opening the fuel filler cap or contacting the fuel nozzle, and avoid re-entering the vehicle during refueling to prevent static electricity buildup.
