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

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. After filling up the tank, the car can usually travel about 500 kilometers. Depending on the engine displacement, cars with higher fuel consumption have larger fuel tanks, while those with lower fuel consumption have smaller ones. During the actual refueling process, the amount of fuel may exceed the calibrated volume. This is because the fuel tank capacity marked by car manufacturers is measured from the bottom of the tank to the safety level, and there is still some space from the safety level to the tank opening. This space ensures that the fuel in the tank can expand when the temperature rises without overflowing the tank's safety space. If the fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the calibrated tank capacity. If the car owner wants to know the remaining fuel level in the tank, they can observe the fuel gauge on the right side of the dashboard, which is marked with E and F. When the pointer is close to E, it indicates that the fuel is running low, and when it is near F, it means the fuel level is sufficient.
When it comes to fuel tank sizes, my experience as a frequent driver tells me that the average capacity ranges between 45 to 65 liters. My family sedan, for example, has a 55-liter tank, and a full tank allows me to drive about 600 kilometers, which is quite convenient for daily commutes. Smaller cars like the Fit have smaller tanks, around 40 liters—they’re fuel-efficient but require frequent stops for refueling on long trips. SUVs such as the Highlander come with larger tanks, over 70 liters, making them ideal for families who enjoy road trips. When refueling, I prefer off-peak hours to save money, but an oversized tank can also be a drawback, as the added weight increases fuel consumption. With the rise of electric vehicles amid environmental trends, fuel tanks are gradually shrinking or being phased out. I believe the choice ultimately depends on individual driving habits, but for safety, it’s best not to fill the tank completely to avoid overflow.
