ABSTRACT:
A lubricated surface, a method for reducing wear between moving parts, and lubricants, and lubricant additive concentrates containing a wear reducing agent. The lubricated surface contains a base oil of lubricating viscosity, a hydrocarbon soluble titanium compound, a metal-free friction modifier and an amount of at least one hydrocarbon soluble magnesium compound effective to provide a reduction in surface wear greater than a reduction surface wear for a lubricant composition devoid of the titanium compound, metal-free friction modifier, and magnesium compound. The lubricant composition contains no more than about 800 ppm phosphorus and is devoid of calcium detergents and organic molybdenum compound.
