There is disclosed a friction reducing compound, comprising an intermediate adduct of a first moiety reacted in a first reaction with a second moiety to form the intermediate adduct and further esterifying or amidafying the intermediate adduct with a third moiety in a molar ratio of from about 1:2 to about 2:1, wherein the first moiety is an unsaturated synthetic dieneophilic base oil, wherein the second moiety is a compound having a diene conjugated carbon-carbon double bond and a carboxylic acid moiety or anhydride group, wherein the first reaction comprises mixing the first moiety with the second moiety in a molar ratio of from about 1:2 to about 2:1 under an inert atmosphere; and wherein the third moiety is a polyhydroxy compound.

Non-phosphorous, non-metallic anti-wear compound and friction modifier

There is disclosed a fuel lubricity additive, made by a two-step process wherein the first step is co-reacting an unsaturated base oil, predominantly from vegetable oil sources, and a compound having a diene structure and a carboxylic acid group, wherein the second step is esterifying or amidifying the free carboxylic acid group of anhydride group with a poly-hydroxy-containing compound or poly-amine compound to form the final fuel lubricity additive useful in diesel fuels. The inventive fuel lubricity additive also is useful as a dispersant.

Fuel lubricity additives

There is disclosed a lubricant additive ingredient that imparts extreme pressure anti-wear properties to lubricant additive compositions. Specifically, there is disclosed a derivative of a vegetable oil triglyceride, a wax ester or a telomerized oil reacted with phosphorous pentasulfide to produce a phosphorous-sulfur (PS) extreme pressure additive.
