Abstract:
There is provided a lubricating composition having a major amount of a lubricating oil having less than about 40% by weight alkylcycloparaffins and a minor amount of at least one diarylamine, and processes for making and using thereof.
Abstract:
Lubricated surfaces, lubricant compositions for lubricating a surface, and methods for reducing friction coefficients in lubricants. The lubricated surface is provided by a lubricant composition containing a base oil of lubricating viscosity and an amount of at least one hydrocarbon soluble titanium compound effective to provide a reduction in the coefficient of friction of the lubricant composition greater than a reduction in the coefficient of friction of the lubricant composition devoid of the hydrocarbon soluble titanium compound.
Abstract:
A lubricant composition comprising a dispersant 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 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.
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:
There is disclosed a lubricating composition comprising a friction modifier and a base oil comprising less than about 3% by weight of tetracycloparaffins. Methods of making and using the composition are also disclosed.

Abstract:
A lubricant composition comprising 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:
There is disclosed a lubricant composition comprising a base oil, wherein the ratio of isoparaffins to normal paraffins in the base oil ranges from about 30 to about 400.
Abstract:
Lubricated surfaces and methods for improving wear performance of gears and bearings are described. The lubricated surfaces include a manganese phosphate film on the surfaces having a film layer density ranging from about 0.1 to about 0.5 milligrams per square centimeter. A lubricating oil containing a phosphorus anti-wear agent is used to provide lubrication of the surfaces.
