A fully formulated lubricating oil, lubricated surface, and lubricant additive concentrates for lubricants providing reduced sludge formation. The fully formulated lubricating oil composition has therein at least one succinimide dispersant derived from a polyalkylene compound having from about 50 to about 85% vinylidene double bonds in the compound, a metal containing detergent, at least one wear reducing agent, at least one antioxidant, and a hydrocarbon soluble titanium compound as a friction modifier. The lubricating oil composition is also substantially free of molybdenum compounds.

Titanium-containing lubricating oil composition

A lubricated surface and method for reducing wear between metal parts. 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.
