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 3-3.
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.
