Arctic Operations
Where there are no provision to keep the engine warm when It is operating in ambient temperatures consistently
below -23°C [-10°F], use a lubricating oil that meets the following requirements.
S A E 5W30 viscosity grade synthetic oils may be used provided they meet the minimum viscosity at 100°C [212°F].

Fuel Specifications
The Cummins Turbo Diesel engine has been developed to take advantage of the high energy content and generally
lower cost No. 2 Diesel Fuels. Experience has shown that it also operates satisfactorily on No. 1 Diesel Fuels or
other fuels within the following specifications.

Carbon Residue (Ramsbottom
ASTM D-524 or 189) .
Not to exceed 1% by weight on 10% residue.
Flash Point (ASTMD-93) 52°C [125°F] minimum. Certain marine
registries require higher flash points.

Cloud Point (ASTM D-97) -12°C [10°F] below lowest temperature expected to operate at.
Active Sulfur Copper
Strip Corrosion (ASTM D-130) Not to exceed No. 2 rating after 3 hours at 50°C [122°F].
Ash (ASTM D-482) Not to exceed 0.02% by weight.
Distillation
(ASTMD-86) The distillation curve should be smooth and continuous. At least 90%
of the fuel should evaporate at less than 360°C [680°F]. All of the
fuel should evaporate at less than 385°C [725°F].
*No. 1 Diesel Fuels should only be used where extended arctic conditions -23°C [-10°F] exist.
