Post-treated molybdenum imide additive composition, methods of making same and lubricating oil compositions containing same.

A lubricating oil composition comprising:

• a. an oil of lubricating viscosity;
• and
• b. the reaction product of
• i. a molybdenum component;
• ii. an imide derived from the reaction product of a hydrocarbyl dicarboxylic acid component and a polyamine component wherein said imide comprises the reaction product prepared by first charging a polyamine to a reaction vessel and then charging a dicarboxylic acid component to the reaction vessel, wherein the charge mole ratio of the hydrocarbyl dicarboxylic acid component to the polyamine component is from about 1:1 to about 1:0.5;
• and
• iii. a post-treating agent, thereby producing a post-treated moblydated succinimide additive composition.

A process for preparing an oil soluble additive composition which comprises reacting:

• (a) a molybdenum component;
• (b) an imide derived from the reaction product of a hydrocarbyl dicarboyxlic acid component and a polyamine wherein said reaction product is prepared by first charging a polyamine to a reaction vessel and then charging a dicarboxylic acid component to the reaction vessel, wherein the charge mole ratio of the dicarboxylic acid component to the polyamine component is from about 1:1 to about 1:0.5;
• and
• (c) a post-treating agent, thereby producing a post-treated moblydated succinimide additive composition.
