The program was conducted in three phases: investigation of more stringent MIL-L-7808 requirements, assessment of MIL-L-23699 oil capabilities, and investigation of advanced new materials. From the program, MIL-L-7808E was upgraded to MIL-L-007808F (USAF) by tightening existing requirements and adding new deposit forming and elastomer compatibility test requirements. MIL-L-7808 and MIL-L-23699 oils were compared and found to be comparable from a deposit forming standpoint. The decision was made to retain the MIL-L-7808 oils as the standard USAF aircraft turbine lubricant. Efforts were initiated to develop better oils than either the 23699 or existing 7808 oils.
