How Big is a Car's Fuel Tank?

[ReaganLee]

Generally, the fuel tank capacity of small cars is 35-45 liters, while that of medium-sized cars is 55-75 liters. A full tank typically allows for a driving range of around 500 kilometers. Depending on the engine displacement of the car, vehicles with higher fuel consumption have larger tanks, while those with lower consumption have smaller tanks. During the actual refueling process, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity specified by car manufacturers is measured from the bottom of the tank to the safe fill level. There is additional space from the safe fill level to the tank opening, which is designed to accommodate fuel expansion due to rising temperatures without causing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added can exceed the calibrated tank capacity. To check the remaining fuel level, drivers can observe the fuel gauge on the right side of the dashboard, which is marked with 'E' and 'F'. When the needle is close to 'E', it indicates low fuel, while nearing 'F' means the fuel level is sufficient.
