Jeep 2015 Grand Cherokee - Diesel Supplement - Manual (Page 101)

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 fol-
lowed as directed.
