Fuel Selection
6.7L Turbo Diesel
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. 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 protec-
tion 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.
