Jeep Grand Cherokee 2015 Owner's Manual page 99

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. 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 provided the shortened
maintenance intervals are followed as directed.
Diesel Exhaust MOPAR® Diesel Exhaust Fluid (API Certified) (DEF) or equivalent that has been API Certified to the
Fluid 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 filters.
