FLUIDS AND LUBRICANTS 3.0L DIESEL ENGINE
Engine
Component Fluid, Lubricant, or Genuine Part
Engine Coolant We recommend you use Mopar Antifreeze/Coolant 10 Year/150,000 Mile Formula OAT (Organic Additive
Technology).
Engine Oil We recommend you use 5W-40 synthetic engine oil such as Mopar or Shell Rotella that meets FCA Material
Standard MS-10902 and the API CJ-4 engine oil category is required.
Engine Oil Filter We recommend you use Mopar Engine Oil Filters.
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 the vehicle is exposed to extreme cold
(below 20°F or -7°C), or is required to operate
at colder-than-normal conditions for pro-
longed 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 filters.
