When is the appropriate time to refuel a car based on remaining gasoline?

[DelEthan]

It is appropriate to refuel when the car has 7 to 10 liters of gasoline remaining. Refueling timing: When within 30 kilometers, it's best to wait until the fuel gauge light comes on before refueling. The fuel gauge light indicates that the fuel tank is almost empty, and there is generally a range of about 7-10 liters remaining when the light comes on. If you are on a highway or in a remote area, you can refuel when the fuel level in the tank is about one-quarter full. Impact of low fuel: When the remaining fuel in the tank is very low, it can affect fuel supply. This is because the vehicle experiences vibrations or tilts while driving, causing the fuel surface to fluctuate along with the car. However, the fuel pump is fixed inside the tank, and there might be brief moments when it cannot draw fuel. Power output can also be affected: if fuel does not flow smoothly into the fuel line, it can disrupt the engine's normal operation, leading to unstable power output.
