How many kilometers can you drive when the fuel gauge light is on?

When the car's fuel gauge light is on, you can generally drive about 30 to 50 kilometers. Here are some precautions for using the fuel gauge: 1. Pointer indication deviation: When the fuel pump is working, the fuel tank is under negative pressure, which reduces the tank volume and raises the fuel level. Additionally, the thermal expansion of gasoline due to temperature can cause the gauge to show a higher reading. When the temperature drops or the fuel tank is opened, the pressure is released, and the fuel level drops accordingly. Therefore, such display deviation is normal, but the deviation generally does not exceed the width of one pointer. 2. Do not continue driving after the warning light comes on: When the warning light comes on, it indicates that the fuel level is too low. Continuing to drive at this point can damage the fuel pump, which is located inside the fuel tank. The fuel pump generates a lot of heat during operation and relies on fuel as its coolant to maintain normal operation. Without sufficient fuel for cooling, prolonged operation will inevitably burn out the fuel pump. 3. Refuel promptly after the warning light comes on: It is essential to refuel immediately after the warning light comes on because the fuel pump in the tank depends on gasoline for heat dissipation and lubrication. Insufficient fuel can impair the pump's normal operation and reduce its lifespan.
The fuel gauge light is a warning of low fuel level. I've been driving for over 20 years and seen this situation many times. Generally speaking, you can still drive about 40-50 to 70-80 kilometers, but don't rely too much on this number. It depends on the car model's fuel consumption - small-displacement vehicles might last longer, but highway driving consumes fuel faster and reduces the range. Once I stubbornly drove over 60 kilometers after the light came on and almost stalled in the city, sweating with anxiety. Many factors affect this: air conditioning usage, full load of luggage, and uphill roads all burn fuel faster. The safest approach is to find a gas station as soon as the light comes on - don't gamble. Make it a habit to regularly check the fuel gauge; maintaining more than half a tank can avoid such risks. Regular vehicle maintenance is crucial too - fuel pumps can overheat and get damaged when fuel is low, and repairs are quite expensive. Saving a little on fuel this way isn't worth it.
The fuel gauge light is on, so you should find a gas station as soon as possible. This indicator means the fuel level has dropped to a dangerously low point, and I advise against waiting. The remaining mileage is roughly between 40 to 80 kilometers, but the faster you drive, the more fuel you consume—it might only last you about ten minutes. I remember last time when the light came on, I got stuck in traffic and barely made it 30 kilometers before almost running out. Besides the mileage issue, too little fuel can cause poor heat dissipation for the fuel pump, and prolonged use like this can damage your car. You should also adjust your driving habits: as soon as the light comes on, I switch to steady driving and avoid sudden acceleration to stretch the fuel a bit further. But the risks are still too high—if your car stalls on the highway, it’s a big problem. Regularly check the fuel pump and gauge system to prevent issues before they arise. Develop a refueling habit: fill up before the tank drops below half to save money and drive with peace of mind.
When the fuel gauge light comes on, I estimate I can drive about 40 to 60 kilometers, but to be conservative, I wouldn't push it beyond 50. Checking the car's manual or the remaining mileage function on the info screen is more accurate. While driving, pay attention: avoid sudden acceleration, turn off the AC to reduce load. As soon as the light comes on, I note down the current mileage and compare it when I reach the gas station for more reliability. Too little fuel can cause the engine to work inefficiently, consuming more fuel and being counterproductive. Prioritize refueling in urban areas to avoid breaking down in remote locations.
