Will Continuing to Drive with the Fuel Light On Damage the Car?

Even when the fuel light comes on, the car can still continue to drive without causing damage. When the fuel light is on, the remaining gasoline in the fuel tank can actually support the car for another 30 to 50 kilometers. Running out of fuel will only cause the car to stall, and it can be driven again once refueled. The fuel light is simply a reminder that the gasoline in the tank is running low and needs to be replenished promptly. The distance the car can travel after the fuel light comes on depends on the specific conditions of the vehicle. In daily use, avoid driving with the fuel light on for extended periods. When the fuel warning light is on, it indicates that the fuel level is below the fuel pump, causing the exposed fuel pump to overheat due to lack of fuel cooling. Continuing to drive under these conditions exposes more of the fuel pump, worsening the overheating situation, which could lead to long-term damage. The best practice is to refuel when the warning light comes on or even before it lights up to ensure the fuel pump does not overheat and get damaged. When refueling, always fill up to the standard line. However, avoid overfilling the tank, as too much gasoline can be dangerous in case of fire and may also block the vent hole, causing damage to car components. Precautions when refueling: Never start the engine while refueling, as it is extremely dangerous; do not smoke in or around the refueling area, as open flames can ignite gasoline; avoid using mobile phones during refueling, as the sudden increase in signal strength when answering a call may generate electronic friction with the gas station's equipment, potentially igniting fuel vapors.
Last time when the fuel light came on, I stubbornly drove another 20 kilometers. The mechanic later told me this habit is extremely damaging to the car. Actually, the fuel pump relies on gasoline for cooling. Running on empty causes the fuel pump to overheat, and replacing it costs several hundred bucks. Sediment at the bottom of the tank might also get sucked into the fuel lines, potentially requiring a full fuel system cleaning. The scariest part was when my car suddenly stalled on the highway once, almost causing a rear-end collision. I've learned my lesson now - when the fuel light comes on, I immediately look for a gas station. Safety comes first.
