I'm considering using this Mil - L - 2105 D oil for the transmission. Any comments with using it?

Gear lubricants acceptable under
military specification (MILSPEC)
MIL-L-2105D (Lubricating Oils,
Gear, Multipurpose) are approved
for use in Spicer Drive Axles.
The MIL-L-2105D specification
defines performance and viscosity
requirements for multigrade oils.
It supersedes both MIL-L-2105B,
MIL-L-2105C and cold weather
specification MIL-L-10324A. This
specification applies to both
petroleum-based and synthetic-
based gear lubricants if they
appear on the most current
"Qualified Products List "
(QPL-2105) for MIL-L-2105D.
NOTE: The use of separate oil
additives and/or friction modifiers
are not approved for use in Spicer
Drive Axles.
Approved Lubricants - Synthetic
based: Synthetic-based gear
lubricants exhibit superior thermal
and oxidation stability, and
generally degrade at a lower rate
when compared to petroleum-
based lubricants. The performance
characteristics of these lubricants
include extended change intervals,
improved fuel economy, better
extreme temperature operation,
reduced wear and cleaner
component appearance. The family
of Spicer gear lubricants represents
a premium quality synthetic lube
which fully meets or exceeds the
requirements of MIL-L-2105D. These
products, available in both 75W-90
and 80W-140, have demonstrated
superior performance in com-
parison to others qualified under
the MILSPEC, as demonstrated by
extensive laboratory and field
testing.
Lube Sampling and Condition
Monitoring: For information,
contact your local Dana represen-
tation at phone numbers listed on
the back cover of this manual.
Makeup Lube: Maximum amount of
non-synthetic makeup lube is 100%.
Viscosity/Ambient Temperature
Recommendations: The following
chart lists the various SAE Grades
covered by MIL-2105D and the
associated ambient temperature
range for each. Those SAE Grades
shown with an asterisk (*) are
available in the Spicer family of
synthetic gear lubricants.
The lowest ambient temperatures
covered by this chart are -40o
F and
-40o
C. Lubrication recommenda-
tions for those applications which
consistently operate below this
temperature range, must be
obtained through the Dana.

Lube Change Intervals
Lubrication Change Internals -
General: The initial lubricant
change is one of the most
important factors in axle com-
ponent life and durability, because
of the elimination of break-in
contaminants. These contaminants
are primarily iron from the initial
break-in wear of rotating
components, and silicon from the
sand used in manufacture of cast
components.
For either a new or rebuilt drive
axle, the lubricant should be
changed within the first 3000 to
5000 miles of operation. Subse-
quent lubricant changes should be
based on a combination of the
intervals stated in the following
chart and user judgment based
heavily on the application and
operating environment.
