Abstract
The present invention relates to functional fluid compositions containing friction modifiers, and specifically stable compositions containing friction modifiers with limited solubility in and/or limited compatibility with the functional fluids with which they are used. In particular the present invention deals with functional fluids used in internal combustion engines, such as engine oils, and friction modifiers that contain one or more amide functional groups, where the friction modifier is present in the functional fluid composition at levels that would otherwise cause the composition to be unstable and/or hazy.
