Abstract: Lubricating and functional fluid compositions are described which comprise at least one oil of lubricating viscosity and an extreme-pressure and friction-modifying amount of (A) at least one phosphite ester characterized by the formula (I) wherein R1 is a straight-chain hydrocarbyl group and R2 is a branched-chain hydrocarbyl group. The invention also relates to compositions which comprise the combination of such phosphite esters as represented by Formula I and various sulfur-containing compositions. The compositions comprising said combinations also are useful in lubricating and functional fluid compositions including lubricating oils and greases. Aqueous systems containing the phosphite esters represented by Formula I as well as combinations of phosphite esters with sulfur-containing compositions also are described.

Abstract: A grease of an oil of lubricating viscosity, a polyolefin having grafted acid functionality, a metallic species capable of interacting with the acid functionality of said polyolefin to cause association among the acid groups and a co-thickening agent, has improved rheological properties. The co-thickening agent and the metallic species can together comprise a gelled overbased material, particularly an over-based carboxylate.
