Abstract:
A lubricant composition comprising a dispersant and a base oil comprising more than about 1.6% by weight of tetracycloparaffins is disclosed. Methods of making and using the lubricant composition are also disclosed.
Abstract:
Lubricated surfaces, lubricant compositions for lubricating a surface, and methods for increasing antiwear properties 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 an increase in antiwear properties of the lubricant composition greater than an increase in antiwear properties of the lubricant composition devoid of the hydrocarbon soluble titanium compound.
Abstract:
Lubricant compositions having improved load carrying capacity comprising an extreme pressure compound comprising a sulfur-containing compound, a load carrying capacity enhancing combination comprising a hydrocarbylamine compound and an alkylphosphorothioate compound, a friction modifier compound, and a diluent or base oil as applicable. These lubricant compositions can be used as industrial oils well-suited for the demands of geared device applications, such as in wind turbine gear-boxes and automotive gears and axles.
Abstract:
A slideway lubricating oil composition, additive concentrate, method of lubricating sliding parts. The lubricating oil includes a base oil; a metal-free friction modifier; and a metal-free, sulfur-free, phosphorus containing anti-wear/extreme pressure agent. The lubricating oil provides a lower coefficient of friction for non-metal sliding surfaces than for metal sliding surfaces.
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.
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 method for reducing a friction coefficient adjacent a lubricated surface, and a lubricant composition for reducing a friction coefficient between lubricated surfaces. The method includes providing an amount of metal-containing dispersed in a fully formulated lubricant composition containing a base oil of lubricating viscosity, wherein the nanoparticles have an average particles size ranging from about 1 to about 10 nanometers. The lubricant composition containing the metal-containing nanoparticles is applied to a surface to be lubricated.
Abstract:
There is disclosed a lubricant composition comprising a base oil comprising a reduced total amount of cyclobenzene as compared to another base oil. Methods of using the lubricant composition for preventing and/or reducing the deposit formation in an engine are also disclosed.
