A/N Grease Specification cross reference:
See The Handbook Maintenance Instructions AN 01-60JE-2 (Revision 12-8-1947 page 69) for the Lube chart for the P-51 aircraft. Shell Technical support updates the AN-G-15 to MIL-G-7711, Aeroshell 6 meets the requirement of this specification. AN-G-25 was superceded by MIL-G-23827 (now MIL-PRF-23827C). Aeroshell 7 & Aeroshell 33 meet this specification, but the formulation of the two are not compatible so do not mix them together in service.
