diesel engines used with advanced aftertreatment systems
(Diesel Particulate Filters – DPF). For complete details on fuel
requirements, see the Engine Operation and Maintenance
Manual supplied with the vehicle.

Hazards of Diesel Fuel / Gasoline Blends
WARNING
To prevent property damage, personal injury, and
/ or death, never add gasoline, gasohol and / or
alcohol to diesel fuel. This mixture creates an
extreme fire and explosion hazard.
Blending of gasoline and / or alcohol with diesel fuel is not
recommended due to the hazards of fire / explosion and the
detrimental effects on engine performance.
As little as 2% volume gasoline mixed with diesel fuel will
create a flammable / explosive mixture in the fuel tank vapor
space, which will pose an extreme fire / explosion hazard during
refueling or engine operation.
Additional Unsafe Practices
CAUTION
To prevent engine damage, do not mix propane
with diesel fuel.
Warranty claims will not be
