  • Stabilized blends containing friction modifiers
    Patent number: 9631160
    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.
