Abstract:
A method for improving oxidation stability and viscosity control, while maintaining or improving cleanliness performance and deposit control, in an engine or other mechanical component lubricated with a lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition including a lubricating oil base stock as a major component, and a mixture of (i) at least one detergent, and (ii) at least one antioxidant, or a mixture of (i) at least one detergent, (ii) at least one dispersant, and (iii) at least one antioxidant, as minor components. The at least one detergent comprises a sulfonate detergent, the at least one dispersant comprises a borated dispersant, and the at least one antioxidant includes an alkylated diphenylamine. The engine or other mechanical component is lubricated with the lubricating oil operating in the presence of biodiesel fuel. A lubricating oil formulated with the above major and minor components.

Claim (Index 17):
A method for improving oxidation stability and viscosity control, while maintaining or improving cleanliness performance and deposit control, in an engine or other mechanical component lubricated with a lubricating oil by using as the lubricating oil a formulated oil, said formulated oil having a composition comprising a lubricating oil base stock as a major component; and a mixture of (i) at least one detergent, (ii) at least one dispersant, and (iii) at least one antioxidant, as minor components; wherein the at least one detergent comprises a magnesium-containing detergent; wherein the at least one dispersant comprises a borated dispersant that provides a boron concentration from about 10 to about 1500 parts per million in said formulated oil; wherein the at least one antioxidant comprises an alkylated diphenylamine; wherein the engine or other mechanical component is lubricated with the lubricating oil operating in the presence of biodiesel fuel; and wherein oxidation stability and viscosity control are improved and cleanliness performance and deposit control are maintained or improved as compared to oxidation stability, viscosity control, cleanliness performance and deposit control achieved using a lubricating oil containing minor components other than the mixture of (i) at least one magnesium-containing detergent, (ii) at least one borated dispersant, and (iii) at least one alkylated diphenylamine antioxidant.
