Zusammenfassung:The present invention is directed to a method for improving one or more of the control of deposit formation and friction in an engine lubricated using a lubricating oil comprising a base oil and additives by employing as the additive the necessary combination of a borated hydroxyl saturated hydrocarbyl ester amide-amine mixture, zinc dialkyl dithiophosphate, and metal salicylate detergent, the deposit formation and friction being improved as compared to a lubricating oil containing the borated hydroxyl saturated hydrocarbyl ester amide-amine mixture, zinc dialkyl dithiophosphate and a detergent other than metal salicylate, such as metal phosphate and/or metal sulfonate.
