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 novel highly grafted, functionalized olefin polymer is provided comprising the reaction product of a method comprising reacting an acylating agent with a mixture comprising an olefin polymer having a number average molecular weight of between about 5,000 to about 100,000 and a diluent in the presence of a free radical initiator to provide an acylated olefin polymer which is further reacted with a polyamine to provide the grafted functionalized olefin polymer dispersant. Lubricating oil concentrates and compositions containing the highly grafted, functionalized olefin polymer and uses thereof also are provided.

Graft functionalized olefin polymer dispersant and uses thereof

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.
