Better than leave safety to chance, here’s a checklist for prewinter maintenance.
• Check the battery
• Check antifreeze levels and the quality of the fluid already in the vehicle’s system
• Replace dirty filters, such as air, fuel, and oil. A poorly running engine is less efficient and burns more gasoline.
• As the temperature drops below freezing, add a bottle of fuel de-icer in the tank about once a month to help keep moisture from freezing in the fuel line.
