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.
Abstract:
A lubricant composition comprising a phosphorus-containing compound and a base oil comprising less than about 3% by weight of tetracycloparaffins is disclosed. Methods of making and using the lubricant composition are also disclosed.
Abstract:
A lubricant composition comprising a detergent and a base oil comprising more than about 1.6% by weight of tetracycloparaffins is disclosed. Methods of making and using the composition are also disclosed.
Abstract:
A method for reducing friction coefficients and wear between lubricated surfaces. The method includes providing an amount of an oil-soluble nanospherical component derived from a photo-crosslinkable poly(2-cinnamoyloxyalkyl acrylate) core and a diblock acrylate copolymer corona in a fully formulated lubricant composition containing a base oil of lubricating viscosity. The nanospherical component has a core diameter ranging from about 10 to about 100 nanometers. The lubricant composition containing the nanospherical component is applied to a surface to be lubricated.

Abstract:
A method of enhancing the operation of diesel fuel combustion systems in a combustion system includes supplying a fuel and additive that includes a manganese compound to a diesel fuel combustion system. The fuel is then combusted in the combustion chamber to produce at least one byproduct including the manganese compound. The manganese compound is supplied in an amount effective to complex with the combustion byproduct. The diesel fuel combustion system operation is enhanced by improving the attributes of lubricating oil loaded with the combustion byproduct soot particles.
Abstract:
There is disclosed a lubricating composition having a base oil, a friction modifier, and a dispersant, wherein the lubricating composition has less than about 325 ppm of boron. Methods of making and using the disclosed lubricating composition are also disclosed.

Abstract:
A method for reducing friction coefficients and wear between lubricated surfaces. The method includes providing an amount of an oil-soluble or oil-dispersible component selected from the group consisting of a photo-crosslinkable poly(2-cinnamoyloxyalkyl acrylate) core and a diblock acrylate copolymer corona in a fully formulated lubricant composition containing a base oil of lubricating viscosity. The lubricant composition containing the component is applied to a surface to be lubricated.
