How many kilometers can you drive after the fuel gauge lights up?

After the car's fuel gauge lights up, you can generally drive about 30 kilometers. Relevant introductions are as follows: 1. It is recommended to check the vehicle condition and fuel situation before driving, and it is best to prepare gasoline in advance. If the fuel gauge light has already come on, if you are on the highway, you should maintain a steady speed, do not brake in a panic, and do not drive at low speed. Find the nearest gas station to refuel as soon as possible. 2. After the fuel gauge light comes on in most cars, there is at least 8L of fuel left in the tank. For models with larger displacements, the remaining fuel will be a bit more. Theoretically, you can drive at least 50 kilometers. However, due to the influence of traffic jams, load, and driving skills, a conservative estimate is that you can still drive about 30 kilometers.
Last time my fuel light came on while driving, I managed to drive about 50 kilometers to find a gas station – it was quite close. I drive a compact sedan with an average fuel consumption of around 7L/100km. When the light comes on, there might be 7-8 liters left in the tank. But it’s really hard to say for sure—it depends on road conditions. On highways, with lower wind resistance and better fuel efficiency, you might squeeze out a bit more distance. In city traffic with constant stop-and-go, fuel burns faster, and you might only have 30-40 kilometers left. Most car manuals suggest a 50-100 km buffer after the fuel light comes on, but in practice, don’t push it too far. Running the fuel pump dry can cause serious damage and expensive repairs. Now, whenever I see the fuel light, I immediately use my phone to navigate to the nearest gas station—no more gambling. It’s not worth risking a breakdown and wasting money on a tow truck.
The fuel gauge light indicates low remaining fuel, with typical tank designs triggering the light at around 5-10% capacity. For example, a 60L tank would have approximately 4-6L left when the light comes on. You can estimate your remaining range by calculating your car's average fuel consumption—for instance, 8L/100km gives a rough idea. However, multiple factors affect this: driving on flat roads may extend the range to 80km, while uphill driving could halve it due to higher fuel consumption. Driving habits also play a crucial role; aggressive acceleration reduces mileage. I recommend following the reference values in your owner's manual and refueling promptly rather than waiting until the tank is completely empty, as this may overheat and damage the fuel pump or cause system failures. Refuel early to maintain vehicle health.
I get nervous as soon as the fuel gauge light comes on. Experience has taught me to find a gas station immediately when it lights up, as the car can only last for about 50-60 kilometers at most. This unpredictability is too dangerous. On highways, faster speeds and strong winds may slightly reduce fuel consumption, but in urban areas with frequent stops at red lights, fuel depletes much faster, with estimates varying widely between 30-80 kilometers. Running out of fuel leads to loss of power, heavier steering, and increased risk of accidents. Moreover, repeatedly pushing the limits damages the car and raises maintenance costs. Keep a navigation system in the car to locate stations promptly, and develop the habit of refueling when the tank is down to a quarter for peace of mind. Safety first—don’t risk saving a few kilometers, as no one wants the embarrassment of pushing a stalled car or calling for rescue.
