ABSTRACT:
A method of controlling the friction coefficients and improving the friction durability of an oleaginous compositions, such as an ATF, comprising adding to the composition a combination of competing additives comprising (1) at least one friction modifying chemical additive having a polar head group and a friction reducing substituent group and (2) at least one non-friction reducing additive and/or friction increasing additive having the same polar group as the friction modifying chemical additive, but having a substituent group which has no material friction raising or lowering effect (non-friction reducing additive) or a substituent group which increases the friction coefficients (friction increasing additive) of the composition.
