When is the best time to refuel a car?

[AsherMarie]

You should refuel when the gauge pointer reaches the quarter mark, which is for the protection of the fuel pump. Relevant explanations are as follows: 1. Impact on lifespan: Nowadays, gasoline vehicles are equipped with electric fuel pumps and electronic fuel level sensors, which need to be immersed in gasoline for heat dissipation. If there is too little gasoline, the fuel pump cannot be immersed, significantly affecting heat dissipation. Untimely heat dissipation will impact the lifespan of the fuel pump and may even cause it to burn out. 2. Instrument panel error: Do not rely solely on the fuel gauge on the car's dashboard for judgment. Most car fuel gauges operate via a float inside the fuel tank that moves up and down, driving an electronic sensor. The sensor then sends the generated electronic signal to the fuel gauge pointer, displaying it on the fuel gauge. However, this method has a large margin of error, and the markings on the fuel gauge cannot accurately reflect the actual amount of fuel remaining in the tank.
