Is it necessary to refuel when the tank is only a quarter full?

When there is a quarter of fuel left, there is still a certain amount of oil, and it is advisable to refuel at this time, but it is best to refuel before the yellow warning light comes on. Many manuals remind that refueling should be done when the gauge pointer reaches the quarter mark, which is for the protection of the fuel pump. Modern gasoline vehicles are equipped with electric fuel pumps and electronic fuel level sensors, which need to be immersed in gasoline for heat dissipation. If the gasoline level is too low, the fuel pump may not be fully submerged, significantly affecting heat dissipation. Poor heat dissipation can shorten the fuel pump's lifespan or even cause it to burn out. If the fuel tank has not been cleaned for a long time, the accumulation of impurities at the bottom can easily clog the fuel lines when the fuel level is low. Additionally, a low fuel level increases the workload of the fuel pump, affecting the cooling of the internal rotor. It may also impact the oxygen sensor in the exhaust system. Standard fuel tank capacity: The labeled capacity of a fuel tank is not the actual maximum capacity but the maximum reasonable capacity. A standard fuel tank can typically hold 10%—15% more than the labeled capacity. For example, a 60-liter tank can hold up to 75 liters. Automakers specify a 60-liter capacity to account for the fuel's expansion coefficient, ensuring that the fuel does not exceed 60 liters to allow sufficient space for expansion due to temperature increases and to maintain safety during use.
