Abstract:
A composition comprising: a high-sulfur API Group I mineral oil base stock; a molybdenum dithiocarbamate in an amount suitable to provide 50 to 600 ppm molybdenum to the composition; a succinimide dispersant based on a polyolefin-substituted succinic structure, where the polyolefin has a number average molecular weight of at least 1500; a zinc dialkyldithiophosphate derived from at least one secondary alcohol; and a hindered phenol, alkylated aromatic amine, or sulfurized olefin oxidation inhibitor, is capable of passing a Sequence III test.
Abstract:
The disclosed technology relates to additive packages for lubricating compositions in diesel and gasoline powered vehicles. In particular, the disclosed technology provides an additive package that can be added to a lubricating composition with oil of lubricating viscosity to improve at least one of (A) piston deposit, (B) piston cleanliness, (C) soot induced viscosity thickening, and (D) oxidation induced viscosity thickening.
Abstract:
The present invention relates to a controlled release gel with an ashless component and defined ash-producing component. Further, the invention relates to the use of a controlled release gel with a controlled level of ash-producing (i.e., metal) components for delivery of additives into lubricants wherein the gel has reduced ash and SAPS producing components.
