Why Does the Fueling Amount Exceed the Tank Capacity?

[BenjaminLynn]

Because the fuel tank capacity provided by the manufacturer refers to the safe capacity of the tank, not the maximum capacity. Here is some expanded information on the topic: Regulations: According to the 'Safety Performance Requirements and Test Methods for Automotive Fuel Tanks,' the safety performance of the fuel tank must meet the requirement that 'the rated capacity should be controlled at 95% of the maximum liquid capacity of the fuel tank.' Typically, the labeled volume is only about 80% to 85% of the maximum capacity. Fueling: Consumers can be completely assured about the quantity when refueling at China Petroleum gas stations, as the fuel dispensers are regularly subjected to mandatory inspections by local technical supervision departments, and the inspection certificates are posted in prominent positions on the fuel dispensers.
