How Big is a Car Fuel Tank?

[VanTimothy]

Generally, the fuel tank capacity of small cars ranges from 35-45 liters, while medium-sized cars have a capacity of 55-75 liters. A full tank typically allows a driving range of about 500 kilometers. The size of the fuel tank correlates with the vehicle's displacement—larger fuel consumption requires a bigger tank, and vice versa. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the fuel tank volume 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 temperature increases, preventing overflow. If fuel is filled up to the tank opening during refueling, the actual fuel amount may exceed the marked tank capacity. To check the remaining fuel level, drivers can observe the fuel gauge on the right side of the dashboard, marked with 'E' (Empty) and 'F' (Full). When the needle approaches 'E,' it indicates low fuel, while nearing 'F' means the tank is sufficiently filled.
