Should You Fill Up the Tank When It's Half Full?

[ArcherRose]

Generally, you should not fill up the tank when it's half full, mainly because a full tank can add extra load to the vehicle and increase fuel consumption. If refueling is necessary, it's advisable to fill up to 80% of the tank's capacity. Below is some relevant information about car refueling: 1. Timing for refueling should be well managed: When the fuel warning light (yellow) comes on, there is still some fuel left in the tank, and this is usually the time to refuel. However, it's best to refuel before the yellow light comes on. Many manuals recommend refueling when the fuel gauge pointer reaches the quarter mark, which is to protect the fuel pump. 2. Safety regulations on fuel capacity: The accuracy of the refueling amount cannot be judged based on the tank's rated capacity. A car fuel tank is a container, not a measuring device, and thus cannot be used as a basis for judging measurement accuracy. According to national mandatory standards, the rated capacity of a car fuel tank should be controlled at 80% of its maximum safe capacity.
