What is the fuel tank capacity of an average car?

Generally, the fuel tank capacity of small cars ranges from 35 to 45 liters, while that of medium-sized cars ranges from 55 to 75 liters. A full tank typically allows a driving range of approximately 500 kilometers. The size of the fuel tank correlates with the vehicle's displacement: cars with higher fuel consumption have larger tanks, while those with lower consumption have smaller ones. During actual refueling, the amount of fuel may exceed the calibrated capacity. This is because the tank capacity specified by car manufacturers measures from the bottom of the tank to the safety level, leaving some space between the safety level and the tank opening. This space ensures that the fuel can expand when temperatures rise without overflowing from the tank. If fuel is added up to the tank opening during refueling, the actual amount of fuel may 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 approaches 'E', it indicates low fuel, while nearing 'F' means the tank is nearly full.
