Abstract
The present invention provides certain metal (e.g., Ca or Mg) ester salt derivatives capable of exhibiting friction modification, oxidation inhibition, and corrosion inhibition properties in power transmitting fluids such as automatic transmission fluids. These salts are derived from mono or diesters prepared by the reaction of an alkanol (e.g., thio-bis-ethanol) and a hydrocarbon substituted succinic acid or anhydride, such as octadecenyl succinic anhydride.
