Fuel Operating Range
NOTE: Use "Ultra Low Sulfur Diesel Fuels" ONLY.
*No. 1 Ultra Low Sulfur diesel fuel should only be used
where extended arctic conditions (-10°F/-23°C) exist.
NOTE:
• Use of Climatized Ultra Low Sulfur Diesel Fuel or
Number 1 Ultra Low Sulfur Diesel Fuel results in a
noticeable decrease in fuel economy.
• Climatized Ultra Low Sulfur Diesel Fuel is a blend of
Number 2 Ultra Low Sulfur and Number 1 Ultra Low
Sulfur Diesel Fuels which reduces the temperature at
which wax crystals form in fuel.
NOTE: The engine requires the use of "Ultra Low
Sulfur Diesel Fuel". Use of incorrect fuel could result in
engine and exhaust system damage. Refer to Fuel Re-
quirements in this section for further details on fuel
recommendations.
