Abstract: Lubricated surfaces, lubricant compositions for lubricating a surface, and methods for increasing antiwear properties in lubricants. The lubricated surface is provided by a lubricant composition containing a base oil of lubricating viscosity and an amount of at least one hydrocarbon soluble titanium compound effective to provide an increase in antiwear properties of the lubricant composition greater than an increase in antiwear properties of the lubricant composition devoid of the hydrocarbon soluble titanium compound.

The lubricated surface contains a base oil of lubricating viscosity and an amount of a hydrocarbon soluble titanium compound effective to provide a reduction in surface wear greater than a surface wear of a lubricant composition devoid of the hydrocarbon soluble titanium compound.

Abstract: A composition for use as an additive for fuels or lubricants. The composition includes a reaction product of a treated amine and a compound selected from the group consisting of hydrocarbyl succinic anhydrides, Mannich adducts derived from hydrocarbyl-substituted phenols reacted with formaldehydes, ethylene-propylene copolymers grafted with ethylenically unsaturated carboxylic groups, copolymers of unsaturated acids and polyolefins, and acid or ester functionalized hydrocarbon polymers. The reaction product is oil soluble and has a number average molecular weight ranging from about 900 to about 50,000 as determined by gel permeation chromatography. The treated amine includes an aliphatic or aromatic amine containing at least one primary or secondary amino group reacted with an aliphatic or aromatic nitrile and hydrogen.

Abstract: The invention relates to a lubricating oil composition having improved antioxidant properties, and which contains a molybdenum compound and an alkylated phenothiazine. Further, it may also include a secondary diarylamine, preferably an alkylated diphenylamine. This combination of additives provides improved oxidation control and friction modifier performance to the lubricating oil. The composition is particularly suited for use as a crankcase lubricant, or a transmission lubricant, including low levels and zero levels of phosphorus.
