Will waiting until the fuel tank warning light comes on to refuel damage the car?

Waiting until the fuel tank warning light comes on to refuel can damage the car. Below are some relevant explanations about waiting until the fuel tank warning light comes on to refuel: Evaporation obstruction: The fuel level indicator usually relies on feedback from the fuel level sensor or inspection as the standard. Therefore, whether it is "fuel" or something else like "water," what it displays is merely a "scale" and does not indicate to the owner whether it is fuel or water. Even with higher-quality fuel, there is a certain "water content." If the vehicle continues to be used in this way for a long time, the water may deposit due to evaporation obstruction (sealing) (water settles at the bottom while fuel floats on the surface), making the indicator show "correct," when in fact, it could potentially cause the engine to stall at any time. Fuel pump: When the fuel level reaches the "warning" line, even if there are no issues with the fuel itself, it can "slosh" due to road bumps, turns, and other driving conditions, preventing the fuel pump from "pumping" fuel in time. This can lead to vehicle shaking, jerking, or stalling due to insufficient fuel supply. Due to the characteristics of certain vehicle models, the fuel pump relies on fuel for cooling. If the fuel level has already reached the lowest mark, the fuel pump may become "exposed" above the fuel surface, failing to receive timely cooling. This can accelerate internal wear, cause premature wear, or lead to internal short circuits and burning due to overheating.
