Use oil viscosity based on the expected air tem-
perature range during the period between oil
changes.
The following oil is preferred:

Mixing of Lubricants
In General, avoid mixing different brands or types of
oil. Oil manufacturers blend additives in their oils to
meet certain specifications and performance re-
quirements. Mixing different oils can interfere with
the proper functioning of these additives and de-
grade lubricant performance.
Grease
Use grease based on the expected air temperature
range during the service interval.
The following greases are preferred:
•
High temperature Moly-Lithium base grease
•
Greases meeting Military Specification
MIL-G-10924F may be used as arctic grease.
