Abstract: The present invention provides a working fluid additive for use in conjunction with a working fluid within an operating system having contact surfaces. The working fluid additive may consist solely of a highly polar material, but preferably includes both a highly polar material and a material that is synergistic to the highly polar material. The highly polar materials have a great affinity for the contact surfaces within the operating system and, therefore, produce film layers on the contact surfaces sufficient to significantly eliminate the frictional losses experience in the boundary regime of lubrication. By including a synergistic polar material, the efficacy as well as the thickness of this film layer is increased to further increase friction reduction. Organo-metallics may be utilized to further decrease wear and friction. An enhancing accelerator may be used to increase the compatibility between the host working fluid and the additive.
