How Far Can You Drive After the Fuel Light Comes On in a Sedan?

When the fuel light comes on in a sedan, you can typically drive approximately 40 to 50 kilometers. The principle behind the fuel light is as follows: there is a float inside the fuel tank that rises with the fuel level when the tank is full, transmitting the level information. As the fuel level decreases, the buoyancy of the float also diminishes. When the fuel in the tank is nearly depleted, the float loses buoyancy and sends a signal to the fuel level sensor, triggering the light to illuminate as a reminder. It is crucial to refuel promptly when the fuel light comes on to avoid damaging the car's fuel pump. The correct steps for refueling are: 1. Slow down and enter the gas station gently, then drive out at a low speed after refueling; 2. Turn off the engine before refueling; 3. After filling up, close the fuel nozzle before restarting the car.
When the fuel light comes on, it means the tank is nearly empty. Based on my years of driving experience, you can usually drive another 50-80 kilometers, depending on the car model and your driving habits. Last time the light came on in my old sedan, I managed to drive about 60 kilometers at low speed in the city before filling up. But my friend with a European brand car said his vehicle stalled after just 40 kilometers. Don't rely solely on memory - monitor the fuel gauge's drop rate, maintain steady driving (avoid high speeds), and minimize AC use to save fuel. Sediment at the tank bottom might get sucked into the fuel pump, potentially damaging components and leading to costly repairs. I recommend refueling early and developing a habit of filling up at half-tank to avoid nighttime station hunts. Navigation apps can provide more accurate remaining distance estimates. Always waiting for the light is risky - it's hard on your vehicle and stressful for you.
