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. The preferred embodiment of the engine treatment oil additive comprises a synergistic blend of chemical constituents including an oil soluble molybdenum additive, polyalphaolefin, ester such as a polyolester or 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 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 st…
