Why does a 50-liter fuel tank get full after adding only 40 liters?

[SanRowan]

Normally, cars display standard fuel levels. For safety and fuel consumption indicators, larger fuel tanks naturally have more reserved space, but it is not recommended to operate at full capacity or overload. Here are some considerations: 1. Fuel tank capacity: The actual capacity of the fuel tank is greater than the nominal capacity. According to fuel safety regulations, national standards stipulate that the nominal capacity of an automobile fuel tank is 95% of the rated capacity. Therefore, when filling up, the fuel quantity can exceed the nominal capacity by 10%. 2. Driving techniques: While a large fuel tank capacity is beneficial, the most fundamental aspect is mastering fuel-saving techniques in daily driving. Under the premise of ensuring safety, avoiding sudden acceleration, sudden deceleration, and other aggressive driving actions can significantly reduce fuel consumption.
