How Much More Fuel Can Be Added When the Tank is Full?
2 Answers
The fuel tank can hold an additional 3 to 6 liters of fuel when it is full. The fuel tank is a container in the car used to store gasoline, made of stainless steel with excellent sealing. It consists of a filler pipe, tank body, fuel tank cap, fuel gauge, and fuel pump. The functions of the fuel tank are: 1. It indicates the fuel grade that the car can use; 2. It displays the standard tire pressure value; 3. It is equipped with a vent hole to drain rainwater. Fuel tanks are classified into: 1. Gasoline tanks and diesel tanks based on the type of fuel; 2. Different structural types including crimped tanks, aluminum alloy tanks, CO2 welded tanks, top-bottom butt-jointed tanks, and end seam-welded tanks.
I've always found the topic of how much more fuel you can add after the tank is full quite interesting. After driving for so many years, I've learned some inside knowledge. Car fuel tanks are designed with a safety buffer zone, typically about 10% of the total capacity, which is reserved for gasoline thermal expansion. For example, if your manual states a 50-liter capacity, you might actually be able to force in about 5 more liters when it's full. While it might sound like a way to save some money, I've personally seen cases where people did this and ended up with fuel leaking everywhere—not only wasting it but also potentially causing a fire. Critical components like the evaporative control valve can get damaged, costing hundreds to repair. So now I always remind my friends: don't be greedy for that small saving. When the pump stops, just quit. Safety should always come first.
