Component Fluid, Lubricant, or Genuine Part
Crankcase Ventilation Filter MOPAR ௡ CCV Filter or equivalent.
Fuel Selection Use good quality diesel fuel from a reputable supplier in your vehicle.
Federal law requires that you must fuel this vehicle with Ultra Low Sulfur
Highway Diesel fuel (15 ppm Sulfur maximum) and prohibits the use of
Low Sulfur Highway Diesel fuel (500 ppm Sulfur maximum) to avoid
damage to the emissions control system. For most year-round service, No.
2 diesel fuel meeting ASTM specification D-975 Grade S15 will provide
good performance. If the vehicle is exposed to extreme cold (below 20°F or
-7°C), or is required to operate at colder-than-normal conditions for pro-
longed periods, use climatized No. 2 diesel fuel or dilute the No. 2 diesel
fuel with 50% No. 1 diesel fuel. This will provide better protection from
fuel gelling or wax-plugging of the fuel filters. This vehicle is fully com-
patible with biodiesel blends up to 5% biodiesel meeting ASTM specifi-
cation D-975.
