Fuel pump damage: When the fuel level is low, the fuel pump has to work harder to draw fuel from the tank. This can cause the pump to overheat and fail prematurely.
Engine damage: If the fuel level gets too low, the engine may not receive enough fuel to operate properly. This can cause the engine to stall, misfire, or even seize.
Catalytic converter damage: The catalytic converter is a device that helps to reduce emissions from the car's exhaust. When the fuel level is low, the catalytic converter can become damaged by the unburned fuel that passes through it.
Increased fuel consumption: Driving with a low fuel level can actually increase the car's fuel consumption. This is because the engine has to work harder to move the car when the fuel level is low.
Towing: If the car runs out of fuel, it will need to be towed to a gas station. This can be costly and inconvenient.
For these reasons, it is important to avoid driving with a low fuel level. If the fuel gauge is getting low, it is best to fill up as soon as possible.
