Fuel Filters — 3.0L Diesel Engine
Fuel Selection — 3.0L Diesel Engine
Diesel Exhaust Fluid — 3.0L Diesel Engine
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.
Component Fluid, Lubricant, or Genuine Part
We recommend using Mopar® Antifreeze/Coolant 10 Year/150,000 Mile (240,000 km)
Formula OAT (Organic Additive Technology) or equivalent meeting the requirements of the
manufacturer Material Standard MS.90032.
We recommend using Mopar® API Certified SAE 5W-40 Full Synthetic Engine Oil which
meets the requirements of the manufacturer Material Standard MS-12991. Equivalent
full synthetic SAE 5W-40 engine oil can be used but must be compliant to API SN/SP and
ACEA A3/B4 specifications Ú page 342.
We recommend using Mopar® Fuel Filter. Must meet 3 micron rating. Using a fuel filter
that does not meet the manufacturer filtration and water separating requirements can
severely impact fuel system life and reliability.
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.
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.
