Abstract (en)
[origin: EP0391649A2] In accordance with the present invention, there are provided ashless heavy duty diesel crankcase lubricating oil compositions which comprise an oil of lubricating viscosity as the major component and (A) at least 2 wt.% of at least one high molecular weight ashless dispersant, (B) an antioxidant effective amount of at least one oil soluble antioxidant material, and (C) a corrosion inhibiting effective amount of at least one organo-sulfur azole or azoline compound, wherein the lubricating oil is characterized by a total sulfated ash (SASH) level of less than 0.01 wt.%.
