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