New Test Procedures for Aircraft Piston Engine Oils 640059

This paper covers the development of single cylinder engine tests for evaluating the new additive-type oils for aircraft piston engines. These procedures utilize the CLR Oil Test Engine. One procedure is designed to evaluate the high temperature oxidation stability of these oils, while the other measures their low temperature sludge dispersancy qualities.*
*Both test methods are incorporated in the new Military Specification MIL-L-22851 (Wep), “Lubricating Oil, Aircraft Reciprocating Engine (ashless dispersant)” used for the procurement of the new additive type oils.
The two procedures appear to be quite repeatable, and thus superior to any previous single cylinder engine tests used for evaluating aircraft engine oils. They were developed by Ethyl Corp. in a study sponsored by the Bureau of Naval Weapons of the U.S. Navy.
