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 including a base oil of lubricating viscosity, at least one metal salt of phosphorothioic acid, and an amount of at least one hydrocarbon soluble titanium compound effective to provide an increase in antiwear properties of the lubricant composition. A ratio of titanium metal to phosphorus in the antiwear agent ranges from about 0.3:1 to about 1.5:1.
