Abstract (en)

[origin: WO2007120712A2] The present invention is directed to a lubricating oil composition comprising a lubricating oil basestock, a boron-containing additive of at least 0.1 weight percent of the composition and less than 8.0 weight percent, and ashless sulfur additive of at least 0.1 weight percent of the composition and less than 4.0 weight percent, a dispersant- detergent-inhibitor system of less than 15 percent weight percent of the composition, a zinc dithiophosphate additive of at least 0.2 weight percent of the composition and less than 2.0 weight percent of the composition. The elements in the forumulated oil composition having at least 100 and less than 630 PPM phosphorus, at least 1,000 PPM and less than 3,000 PPM, at least 100 and less than 630 ppm Phosphorous, and at least 105 PPM and less than 710 PPM zinc. In a second embodiment, an additive composition for lubricating oils is disclosed. In a third embodiment, a method to obtain favorable lubricating properties is disclosed.
