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).

Fluid, Lubricant, or Genuine Part
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.
