viscosity index improve additive which has a tendency to
lose its effectiveness after a short period of use in a high
speed engine.
These oils should be avoided.
2. Oils which meet the low temperature SAE
viscosity standard (O deg.
F [18 deg.
C]) carry a suffix
"W." Oils that meet the high temperature viscosity SAE
standard (210 deg.
F [99 deg.
C] ) as well as the low
temperature carry both viscosity ratings example:
2020W. See Table 182.

Arctic Operations
For operation in areas where the ambient temperature is
consistently below 10 deg.
F [23 deg.
C] and there is no
provision for keeping engines warm during shutdowns,
the lubricating oil should meet the requirements in Table
18-3.

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 void, and
SAE 5W oils should not be used.
GREASE
Cummins Engine Company, Inc., recommends use of
grease meeting the specifications of MIL-G-3545,
excluding those of sodium or soda soap thickeners,
Contact lubricant supplier for grease meeting these
specifications.

CAUTION
Do not mix grease and lubricating oil 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 rotate speed.
