The fuel tank volume (L) refers to the fuel capacity of the car, which determines the mileage. Two cars with the same engine, the bigger the fuel tank, the farther they run. Fuel tank capacity calculation unit: international standards all adopt L (liter) as the calculation unit of automobile fuel tank capacity, and different countries have corresponding standards for automobile fuel tank capacity.
The actual capacity of the fuel tank is greater than the nominal capacity. According to the characteristics of fuel safety, the country stipulates that the nominal capacity of automobile fuel tank is 95% of the rated capacity, so it can be 10% more than the nominal capacity when filled with oil.
