RECAUTIONS
Operation in ambient temperature below 32°F (0°C) may
require special considerations. The following charts
suggest these options:
Fuel Operating Range
NOTE:
Use Ultra Low Sulfur Diesel (ULSD) Fuels ONLY.
Fuel Operating Range Chart
*Number 1 ULSD Fuel should only be used where
extended arctic conditions 0°F (-18°C) exist.
NOTE:
Use of Climatized ULSD Fuel or Number 1 ULSD fuel
results in a noticeable decrease in fuel economy.
Climatized ULSD fuel is a blend of Number 2 ULSD fuel
and Number 1 ULSD fuel which reduces the tempera

ture at which wax crystals form in fuel.
The fuel grade should be clearly marked on the pump
at the fuel station.
The engine requires the use of Ultra Low Sulfur Diesel
Fuel. Use of incorrect fuel could result in engine and

ment (or equivalent) is recommended to avoid gelling
(see Fuel Operating Range Chart).
Engine Oil Usage
See Engine Fluids and Lubricants for the correct engine oil
Engine Warm-Up
Avoid full throttle operation when the engine is cold. When
starting a cold engine, bring the engine up to operating
speed slowly to allow the oil pressure to stabilize as the
engine warms up.
If temperatures are below 32°F (0°C), operate the engine
at moderate speeds for five minutes before full loads are
applied.

DLING
Avoid prolonged idling. Long periods of idling may be
harmful to your engine because combustion chamber
temperatures can drop so low that the fuel may not burn
completely. Incomplete combustion allows carbon and
varnish to form on piston rings, cylinder head valves,
turbocharger, and injector nozzles. Also, the unburned
fuel can enter the crankcase, diluting the oil and causing
rapid wear to the engine.
