What are the precautions when refueling?

When refueling, you should avoid overfilling the tank and try to avoid waiting until the fuel warning light comes on. Below are the relevant details about car refueling: Avoid overfilling the tank: If the tank is filled too full, the high summer temperatures and the heat generated by the car itself can cause the gasoline to expand. To prevent the fuel tank from being damaged by the expanding gasoline, there is a vent hole at the top. Try to avoid waiting until the fuel warning light comes on: While driving, always monitor the fuel gauge. When the gauge indicates that only a quarter of the fuel remains, it's time to refuel. Do not wait until the fuel warning light comes on. Modern cars use electric fuel pumps that rely on gasoline for lubrication and cooling. Frequently waiting until the fuel light comes on can prevent the fuel pump from receiving adequate lubrication and cooling, ultimately reducing its lifespan.
Refueling while driving may seem trivial, but caution is crucial. I always turn off the engine first, as the heat from a running engine could ignite fuel vapors, posing serious fire hazards. Smoking or using mobile phones during refueling is absolutely prohibited, since sparks or static electricity may ignite fuel vapors—I've personally witnessed startling incidents caused by phone rings. Winter demands extra vigilance against static electricity; always discharge it by touching the car's metal body before handling the fuel nozzle. Monitor the fuel gauge and avoid hastily removing the nozzle when full—let it stop gradually to prevent wasteful spills and environmental contamination, which are troublesome to clean. Finally, ensure the fuel cap is tightly secured to prevent vapor leaks or water ingress that could damage the engine. Adopting these habits ensures safety and peace of mind during travels.
