    Abstract: An object of the present invention is to provide an oil soluble compound and a lubricating composition and method of using the same in a differential. The compound can be of formula R′N((CH2)2CONHR″)2, wherein R′ can be H or a C8-28 hydrocarbyl group wherein up to 4 carbon atoms in the hydrocarbyl group may optionally be replaced by nitrogen or oxygen atoms, and R″ can be H or a C8-28 hydrocarbyl group. The invention further provides a method of producing an oil soluble compound suitable for limited slip performance. The method comprises preparing a Michael adduct from an acrylate and an alkylamine of formula R′NH2, followed by subjecting the Michael adduct to an amidation reaction with a further alkylamine of formula R″NH2.
