What is the general fuel tank capacity of a car in liters?

[DeFernando]

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 is correlated with the car's displacement and fuel consumption—larger fuel consumption corresponds to a larger tank, and vice versa. During actual refueling, the amount of fuel added 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 safety limit. There is additional space from the safety limit to the tank opening, which is designed to accommodate fuel expansion due to temperature increases, preventing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the calibrated tank capacity. To check the remaining fuel level, drivers can observe the fuel gauge on the right side of the instrument panel, which is marked with 'E' and 'F'. When the needle approaches 'E', it indicates low fuel, while nearing 'F' signifies sufficient fuel.
