| Summary: | During the past decade synthetic oils have been introduced into engine test programs in the U.S. Army. These test programs have ranged from evaluation of vehicle fleet operation to engine test development for arctic engine oil specifications. Both performance and physico-chemical properties have been evaluated including the development of analytical schemes to identify lubricant base stock composition. In many respects, routine oil analyses have not been influenced by the nature of a lubricant's base stock (as to whether it is mineral oil or synthetic oil base stock). However, some laboratory tests have been rendered useless while others have been enhanced with respect to their applicability to synthetic-based lubricants as opposed to mineral oil-based lubricants. This report has as its objective to place in perspective the Army's experience primarily with ground vehicle engine lubricants so as to illustrate the impact synthetic and hybrid oil base stocks have had in the analysis of new and used engine oils. |
