ENGINE FLUIDS AND LUBRICANTS
6.4L GASOLINE ENGINE
6.7L DIESEL ENGINE
Component Fluid, Lubricant, or Genuine Part
Engine CoolantWe recommend using Mopar® Antifreeze/Coolant 10–Year/150,000 Mile
(240,000 km) Formula OAT (Organic Additive Technology).
Engine Oil We recommend using Mopar® API Certified SAE 0W-40 Full Synthetic Engine Oil which meets the
requirements of the manufacturer Material Standard MS-A0921. Equivalent full synthetic SAE 0W-40
engine oil can be used but must have the API Donut trademark Ú
page 354.
Fuel Selection 87 Octane (R+M)/2 Method, 0-15% Ethanol (Do not use E-85).
Component Fluid, Lubricant, or Genuine Part
Engine CoolantWe recommend using Mopar® Antifreeze/Coolant 10 Year/150,000 Mile
(240,000 km) Formula OAT (Organic Additive Technology).
Engine Oil In ambient temperatures above 0°F (-18°C), we recommend using 10W-30 engine oil such as Mopar®,
Shell Rotella and Shell Rimula that meets the manufacturer Material Standard MS-10902 and the API CK-4
engine oil category is required. Products meeting Cummins® CES 20081 may also be used. The
identification of these engine oils is typically located on the back of the oil container.
In ambient temperatures below 0°F (-18°C), we recommend using 5W-40
synthetic engine oil such as
Mopar®, Shell Rotella and Shell Rimula that meets the manufacturer Material Standard MS-10902 and the
API CK-4 engine oil category is required.
Fuel Filters We recommend using Mopar® Fuel Filter. Must meet 3 micron rating (engine mounted filter). Must meet
5 micron rating (chassis mounted filter).
Using a fuel filter that does not meet the manufacturer’s filtration
and water separating requirements can severely impact fuel system life and reliability.
Crankcase Ventilation Filter We recommend using Mopar® CCV Filter.

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, Number 2 diesel fuel meeting ASTM specification D-975 Grade S15 will
provide good performance.
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.
This vehicle is fully compatible with biodiesel blends up to 5% biodiesel meeting ASTM specification D-975.

Pickup models, and Chassis Cab models configured with optional B20 capability, are additionally
compatible with 20% biodiesel meeting ASTM specification D-7467.
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. You can receive
assistance in locating DEF in the United States by calling 866-RAM-INFO (866-726-4636). In Canada call
1–800–465–2001 (English) or 1–800–387–9983 (French).

CAUTION!
Mixing of engine coolant (antifreeze) other than specified Organic Additive Technology (OAT) engine coolant (antifreeze), may result in engine damage and
may decrease corrosion protection. Organic Additive Technology (OAT) engine coolant is different and should not be mixed with Hybrid Organic Additive Tech -
nology (HOAT) engine coolant (antifreeze) or any “globally compatible” coolant (antifreeze). If a non-OAT engine coolant (antifreeze) is introduced into the
cooling system in an emergency, the cooling system will need to be drained, flushed, and refilled with fresh OAT coolant (conforming to MS.90032), by an
authorized dealer as soon as possible.
Do not use water alone or alcohol-based engine coolant (antifreeze) products. Do not use additional rust inhibitors or antirust products, as they may not be
compatible with the radiator engine coolant and may plug the radiator.
This vehicle has not been designed for use with propylene glycol-based engine coolant (antifreeze). Use of propylene glycol-based engine coolant (anti -
freeze) is not recommended.
