How Many Kilometers Can You Drive When the Fuel Gauge is Empty?
1 Answers
When the fuel gauge light comes on, the car can typically run for about 30 to 50 kilometers. Below are some precautions regarding the use of the fuel gauge: Pointer Indication Deviation: When the fuel pump is operating, a negative pressure is created inside the fuel tank, which reduces the tank's 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 decreases accordingly. Therefore, such display deviations are normal. However, the deviation usually does not exceed the width of one pointer. Avoid Continuing to Drive When the Indicator Light Comes On: When the indicator light comes on, it means the fuel level is critically low. Continuing to drive under these conditions can be harmful because the fuel pump, located inside the fuel tank, generates significant heat during operation. Fuel acts as a coolant for the pump, ensuring it operates properly by continuously cooling it. Without sufficient fuel for cooling, prolonged operation of the fuel pump will inevitably lead to burnout. Refuel Promptly When the Indicator Light Comes On: It is essential to refuel as soon as the indicator light comes on. This is because the fuel pump relies on gasoline for both cooling and lubrication. A low fuel level can impair the pump's normal operation and shorten its lifespan.
