Component Fluid, Lubricant, or Genuine Part
Fuel Selection Use good quality diesel fuel from a repu-
table 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 dam-
age 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. We
recommend you use a blend of up to 5%
biodiesel, meeting ASTM specification
D-975 with your diesel engine.This vehicle
is compatible with biodiesel blends greater
than 5% but no greater than 20% biodiesel
meeting ASTM specification D-7467 pro-
vided the shortened maintenance intervals
are followed as directed.
Diesel Exhaust Fluid MOPAR
®
Diesel Exhaust Fluid (API Certi-
fied) (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.
NOTE:
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 filter.
