Reformulation of a developmental MIL-L-27502 ester lubricant - MCS 1034A - undertaken to produce an improved oil of greater oxidation resistance and longer shelf life. Two new formulations resulted a An oil with oxidative stability similar to the reference ester at 428F, but with improved stability at 464F. After 72 hours at 464F the viscosity increase of the new fluid is only one-half that of the reference--the acid number is about one-third that of the reference and b An oil with oxidative properties comparable to the reference ester but with improved storage life. Five gallons of fluid a were blended and forwarded to WPAFB for further evaluation.
