What is the appropriate amount to fill the fuel tank?

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.
I've been driving for over a decade and have some insights on refueling. Generally, don't fill the tank too little - it's best to fill it up until the pump automatically stops. Why do I say this? Because the fuel pump relies on fuel for cooling, and low fuel levels can cause the pump to overheat and fail. Moreover, sediment often accumulates at the bottom of the tank. Only filling halfway each time allows impurities to build up thicker, which can affect fuel system cleanliness in the long run. I learned this the hard way - waiting until the fuel light came on before refueling ended up costing me over a thousand yuan in pump repairs. So I recommend filling up completely each time; don't try to save those few bucks on fuel. If you're taking a long trip, a full tank also means fewer stops at gas stations, saving both time and fuel. Of course, don't overfill past the expansion port to prevent overflow from thermal expansion in summer. Regular maintenance checks on the fuel system are also important - I do mine every six months.
