What Happens If You Exceed the Fuel Tank Capacity?
1 Answers
It is normal for the amount of fuel filled to exceed the tank's rated capacity. During the actual refueling process, the fuel volume may surpass the calibrated capacity. This occurs because the fuel tank capacity specified by the car manufacturer is measured from the bottom of the tank to the safe limit. There is still some space from the safe limit to the tank opening, which is reserved to allow for fuel expansion when temperatures rise, preventing overflow. If fuel is filled up to the tank opening during refueling, the actual fuel volume will exceed the rated tank capacity. If car owners want to check the remaining fuel level, they can observe the fuel gauge on the right side of the dashboard, which is marked with 'E' and 'F.' When the pointer is close to 'E,' it indicates low fuel, while nearing 'F' means the fuel level is sufficient. Fuel tank maintenance includes the following steps: Drain accumulated water and sediment from the tank, and check for fuel leaks at pipe joints and valves. For fuel tank caps equipped with air valves and vapor valves, ensure the vent holes are clear. The filter screen at the fuel filler neck should remain intact to prevent impurities from entering the tank during refueling and clogging the fuel lines. The sealing gasket on the fuel filler cap should also be in good condition to avoid fuel spillage while driving.
