Cold Weather Starting Tips • Save the batteries. Do not overtax the batteries by cranking the starter for more than 30 seconds without interruption. Allow about two minutes between attempts at starting the vehicle; this allows the starter to cool and the batteries to re-energize. Note: Always make sure that the battery is fully charged in cold weather. • Use the correct grade of oil for the prevailing winter temperature. • Drain the fuel tanks and filters regularly to prevent water accumulation in the fuel system. This accumulation can freeze in fuel tanks, fuel lines and filters.
WARNING Do NOT — under any circumstances — add gasoline, alcohol, used oil or additives with metallic particles to the fuel.
• If the fuel gels and starts clogging filters and small passages, mix a small percentage of No. 1K fuel (kerosene) with Ultra-Low Sulfur (15 ppm max) No. 2D (diesel) fuel. Note: Adding kerosene is NOT recommended for general use because both performance and fuel economy will be reduced. • Refer to the Maintenance and Lubrication Manual for additional cold weather operating information.
