Component Fluid, Lubricant, or Genuine Part
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 perfor-
mance. 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 the vehicle is exposed to extreme cold (below
20°F or -7°C), or is required to operate at colder-than-
normal conditions for prolonged 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 filter.
