Component Fluid, Lubricant, or Genuine Part
Fuel Filters We recommend you use Mopar Fuel Filter. Must meet 3 micron rating. Using a fuel filter that
does not meet the manufacturers filtration and water separating requirements can severely
impact fuel system life and reliability.
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. We recommend you use a blend of up to 5% biodiesel, meeting ASTM
specification D-975 with your diesel engine.
This vehicle is compatible with biodiesel blends
greater than 5% but no greater than 20% biodiesel meeting ASTM specification D-7467
provided the shortened maintenance intervals are followed as directed.
Diesel Exhaust Fluid Mopar Diesel Exhaust Fluid (API Certified) (DEF) or equivalent that has been API Certified to the
ISO 22241 standard. Use of fluids not API Certified to ISO 22241 may result in system damage.
NOTE: If climatized or diesel Number 1 ULSD fuel is not
available, and you are operating below (20°F/-6°C), in
sustained arctic conditions, Mopar Premium Diesel Fuel
Treatment (or equivalent) is recommended to avoid gelling.
