Abstract

A lubricant additive formulation for increasing the performance of conventional engine lubricants for use as an engine treatment oil additive formulated for addition to conventional motor oil to improve the lubricating properties of the engine oil and enhance the performance of the engine. A preferred embodiment of the engine treatment oil additive comprises a blend of chemical constituents including a base stock selected from a synthetic base stock, a mineral oil base stock, and a severely hydrocracked base stock or combinations thereof, an oil soluble molybdenum additive, dispersant inhibitor, and selected additives such as polytetrafluoroethylene, viscosity index improvers, and extreme pressure wear agent used in combination with a conventional crankcase lubricant at about a 20 to about a 25% volume/percent or as a complete motor oil. Additional components may be added to the engine treatment oil additive formulation to enhance specific properties for special applications.
