What is the capacity of a car's fuel tank?

[Matt]

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 usually allows for a driving range of approximately 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 marked 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 temperature increases without causing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added 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, which is marked with E (Empty) and F (Full). When the needle is close to E, it indicates that the fuel is running low, while proximity to F means the fuel level is sufficient.
