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 Number 2 diesel fuel or dilute the Number 2 diesel fuel with 50% Number 1 diesel fuel. This will provide better protection from fuel gelling
or wax-plugging of the fuel filters.
Fuel Selection — 3.0L Diesel Engine
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, Number 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 — 3.0L Diesel Engine
Mopar® Diesel Exhaust Fluid (DEF) (API Certified) 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.
