Abstract: A motor oil performance-enhancing 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. The novel engine additive comprises a synergistic combination of chemical constituents including an oil soluble molybdenum additive, polyalphaolefin, diester, polytetrafluoroethylene, dispersant inhibitor containing zinc dithiophosphate, mineral oil base stock, viscosity index improvers, and borate ester used in combination with a conventional crankcase lubricant at about a 20 to about a 25% volume/percent. The improved performance of the engine additive in comparison with conventional crankcase lubricants is attributable to the synergistic effect of optimizing the design parameters for each of the individual chemical constituents and combining the chemical constituents according to the present invention to obtain surprisingly good results including improved: wear, oxidation resistance, viscosity stability, engine cleanliness, fuel economy, cold starting, and inhibition of acid formation. The novel engine additive formulation comprises a synergistic combination of compounds, ingredients, or components, each of which alone is insufficient to give the desired properties, but when used in concert give outstanding lubricating properties. Of course, it is contemplated that additional components may be added to the engine additive formulation to enhance specific properties for special applications.
