ENGINE FLUIDS AND LUBRICANTS

Engine Coolant

We 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 American Petroleum Institute (API) Approved Engine Oil.

Fuel Selection

87 Octane (R+M)/2 Method, 0-15% Ethanol (Do not use E-85).

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 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 configured with optional B20 capability, are additionally compatible with 20% biodiesel meeting ASTM specification D-7467.

Diesel Exhaust Fluid

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. 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).
