How many kilometers can you drive when the fuel gauge light comes on?
2 Answers
The fuel gauge light indicates that you can still drive for 30 to 50 kilometers. The function of the fuel gauge is to display the fuel level in the car's fuel tank. The fuel gauge consists of a voltage regulator, a fuel indicator, and a fuel level sensor. The low fuel level warning device is designed to illuminate immediately when the fuel in the tank falls below a specified level, alerting the driver to take action. Precautions for using the car fuel gauge include: 1. Do not wait until the warning light comes on to refuel; insufficient fuel level is detrimental to the normal operation of the fuel pump and reduces its service life. 2. Display deviation: When replacing the battery or fuel filter and restarting the vehicle, the fuel gauge pointer may show a lower position than before. This is due to the release of pressure after opening the fuel tank, causing the fuel level to drop. This display deviation is a normal phenomenon.
I have plenty of experience with the fuel gauge light coming on, having driven for decades across all kinds of road conditions. Based on my experience, when the light comes on, the car can usually go another 40 to 80 kilometers, but it varies. My old car had a large fuel tank and could sometimes make it over 60 kilometers, but in city traffic with stop-and-go driving, the range would quickly drop to around 30 kilometers. On the highway at a steady speed, it might stretch to 70 kilometers—but don’t push your luck. Running the AC in summer or climbing hills can spike fuel consumption by 20-30%, so once the light comes on, head straight to a gas station. I once pushed it for 40 kilometers and nearly ran out—the engine sputtered and stalled just as I arrived, costing me a fortune in repairs. Now, I make it a habit to refuel when the tank is half empty—it saves stress and money. General advice: Act quickly when the light comes on; don’t wait for the absolute limit.
