The objective was to develop a test rig and a procedure to evaluate experimental gas turbine lubricants at surface temperatures up to 1000F and to yield results that are indicative of lubricant performance in advanced high mach gas turbine engines with respect to sludge, coke, acidity, and viscosity change. The program covered by this report was directed to studying the effect of variables on a polyphenyl ether, 0-61-20, utilizing a 48-hour test. Major emphasis was placed on the formation of deposits. Tests were also conducted on engine-tested MIL-L-7808 oils to further check the correlation previously established. Author
