TECHNICAL SPECIFICATIONS

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 Tech

-

nology (OAT) engine coolant is different and

should not be mixed with Hybrid Organic

Additive Technology (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 autho

-

rized 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 (antifreeze) is not recom

-

mended.
