ABSTRACT:
An oil particularly suited for equipment having copper containing alloy elements, is compounded from about 20 to 99.75% by weight of natural or synthetic oil, and about 0.25 to 30% by weight of an acid forming friction modifier, particularly, a fully esterified compound, such as glycerol trioleate (GTO). The oil evidences a marked improvement in frictional behavior and wear protection, especially regarding the corrosive wear of Cu based alloys. The oil containing glycerol trioleate does not release oleic acid unless and until boundary conditions are present, thereby on one hand effectively lubricating under boundary conditions, while on the other hand minimizing the presence of oleic acid and thereby reducing chemical wear.
