Engine Coolant
We 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 require-
ments 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 mod-
els, and Chassis Cab models configured with optional B20 capability, are additionally compatible with 20% biodiesel meet-
ing 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–
