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.
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 dam-
age to the emissions control system.
For most year-round service, No. 2 diesel fuel meeting ASTM specifica-
tion 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 7% 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 Certi-
fied to ISO 22241 may result in system damage.
