Driving on Low Fuel
Constantly driving with a low fuel tank stresses your car’s fuel system. The fuel pump relies on gasoline to stay cool, and when fuel is low, the pump may overheat. Over time, this can damage the fuel pump, which is often costly to replace.
Keeping your tank at least a quarter full is an easy way to avoid this issue. Driving with low fuel also increases the chance of sediment buildup clogging your fuel filter. Gasoline often contains impurities that settle at the bottom of the tank.
