When should I refuel based on the fuel gauge needle?

[AdalineFitz]

The fuel gauge needle indicates it's time to refuel when it reaches the red line. Be careful not to wait until the gasoline is completely exhausted before refueling, as this can damage the car's engine. The fuel gauge is a tool used to determine the fuel capacity status of a vehicle. Depending on the model, fuel gauges are generally categorized into analog (needle-type) and digital types. The fuel gauge primarily measures the fuel level in the car's tank using a fuel float, which then changes the current passing through the fuel gauge via a variable resistor at the end of the float to determine the fuel capacity. Precautions for using fuel: 1. Try to use high-quality fuel; 2. Do not overfill the tank when refueling; 3. Avoid waiting until the gasoline is completely depleted before refueling.
