Component Fluid, Lubricant, or Genuine Part
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, No. 2 diesel fuel meeting ASTM specification D-975 Grade S15
will provide good performance.
If the vehicle is exposed to extreme cold (below 20°F or -7°C), or is required to operate at
colder-than-normal conditions for prolonged periods, use climatized No. 2 diesel fuel or
dilute the No. 2 diesel fuel with 50% No. 1 diesel fuel. This will provide better protection
from fuel gelling or wax-plugging of the fuel filters.
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
