Fuel Selection 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 pro-
tection 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. Pickup models, and Chassis Cab models configured with op-
tional B20 capability, are additionally compatible with 20% biodiesel meeting ASTM specifi-
cation D-7467.
