Arctic Operations
For operation in areas where the ambient temperature is
consistently below -10 deg F [-I23 deg C] and there is no
provision for keeping engines warm ’during shutdowns,
the lubricating oil should meet the requirements in Table
33.
Due to extreme operating conditions, oil change intervals
should be carefully evaluated paying particular attention
to viscosity changes and total base number decrease.
Oil designed to meet MIL-L-10295-A, which is now void,
and SAE 5W mineral oils should not be used.

Caution:
Do not mix brands of grease as damage to
bearings may
result.
Excessive
lubrication
is as
harmful
as inadequate lubrication.
After lubricating fan
hub, replace both pipe plugs.
Use of fittings will allow
lubricant to be thrown out, due to rotative speed.
Fuel
Cummins Diesel Engines have been developed to take
advantage of the high energy content and generally
lower cost of No. 2 Diesel Fuels.
Experience has shown
that a Cummins Diesel Engine will also operate
satisfactorily on No. 1 fuels or other fuels within the
following specifications.
