What is the appropriate amount to fill the fuel tank?

[DiFelix]

According to the relevant mandatory national standards, the rated capacity of a vehicle fuel tank should be controlled at 95% of the maximum safe capacity of the fuel tank. Taking a 60-liter fuel tank as an example, it can be filled up to a maximum of 75 liters, but the stored fuel should not exceed 60 liters. More relevant information is as follows: 1. The accuracy of the refueling amount cannot be judged based on the rated capacity of the fuel tank. The fuel tank of a fuel-powered vehicle is a container, not a measuring tool, so it cannot be used as a basis for judging measurement accuracy. Moreover, according to the relevant mandatory national requirements, the rated capacity of a vehicle fuel tank should be controlled at 95% of the maximum safe capacity of the fuel tank. 2. Many vehicle fuel gauges operate through the up and down movement of a float inside the tank, which drives an electronic sensor. The sensor then transmits the generated electronic signal to the fuel gauge pointer, displaying it on the fuel gauge, resulting in significant potential errors.
