We recommend using Mopar® Antifreeze/Coolant 10 Year/150,000 Mile (240,000 km) Formula OAT (Organic Additive
Technology).
Engine Oil — 3.0L Turbo
Diesel Engine
We recommend using 5W-40 synthetic engine oil such as Mopar® that meets the manufacturer Material Standard MS-12991
and the API SP engine oil category is required.
Diesel Engine Oil Filter
We recommend using Mopar® engine oil filters. Using an oil filter that does not meet the manufacturer’s filtration
requirements can severely impact engine life and reliability.
Fuel Filters — 3.0L Turbo
Diesel Engine
We recommend using Mopar® fuel filter. Must meet 3 micron rating. Using a fuel filter that does not meet the manufacturer’s
filtration and water separating requirements can severely impact fuel system life and reliability. Under normal conditions the
diesel fuel filter should be replaced every 20,000 miles (32,000 km) (every other oil change). If the vehicle is being used in
severe operating conditions, or In certain geographical areas of the country (Pennsylvania, New York, Ohio, Maryland, West
Virginia, Arkansas, Oklahoma, Kansas, Iowa, Missouri and Nebraska) due to fuel cleanliness issues, it’s recommended to
replace the fuel filter every 10,000 miles (16,000 km).
Fuel Selection — 3.0L Turbo
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
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.
