6. Refueling only when the tank is almost empty
Mechanical impurities build up in the gasoline tank, and sludge develops at the bottom of your car while it is not in use. The harm is caused when the dirt enters the fuel pump and filters. Always keep the tank at least halfway full of fuel during the winter to prevent the buildup of significant amounts of condensate. Water in the gasoline tank during cold temperatures might cause distortion and other issues.
