Fuel Selection
(5.9L Diesel Engine)Use good quality diesel fuel from a reputable supplier. For most year-round service,
No. 2 diesel fuel meeting ASTM specification D-975 will provide good performance. If
the vehicle is exposed to extreme cold (below 20 degrees F or -7 degrees C), or is re-
quired to operate at colder-than-normal conditions for prolonged periods, use clima-
tized 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-6751.

Fuel Selection
(6.7L Diesel Engine)Use good quality diesel fuel from a reputable supplier in your vehicle. Federal law re-
quires 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.
