Zusammenfassung:Disclosed is a lubricating oil composition comprising (a) a major amount of an oil of lubricating viscosity having a kinematic viscosity at 100° C. in a range of about 2 to about 50 mm2/s; (b) a hydrocarbyl succinimide dispersant; (c) a borated hydrocarbyl succinimide dispersant; and (d) a hydrocarbyl succinimide post-treated with a post-treating agent selected from the group consisting of an organic carbonate, an epoxide, a lactone, a hydroxyaliphatic carboxylic acid, and combinations thereof.
