Abstract:

A power transmission fluid comprising a mixture of a major amount of a lubricating oil and an effective amount of a performance enhancing additive combination comprising: (a) at least one organic phosphate having the structure R âX âP(:X )(R X )âXâR where R , and R may independently be substituted or unsubstituted alkyl, aryl, alkylaryl or cycloalkyl having 1 to 24 carbon atoms and X, X , X and X may independently be sulfur or oxygen. R and R may also contain substituent hetero atoms, in addition to carbon and hydrogen, such as chlorine, sulfur, oxygen or nitrogen; wherein R is derived from a reactive olefin and can be either CH âCHRâC(:O)OâR ; âCH âCR HR ; or R âOC(:O)CH âCHâC(:O)OâR where R is H or the same as R , R , R , R and R are the same as R and R is a phenyl or alkyl or alkenyl substituted phenyl moiety, the moiety having from 6 to 30 carbon atoms, (b) a calcium detergent, and (c) a friction modifier.
