The invention provides lubricating composition comprising: an oil of lubricating viscosity, and an oxyalkylated hydrocarbyl phenol, wherein the oxyalkylated hydrocarbyl phenol is substituted with at least one aliphatic hydrocarbyl group of 40 to 96 carbon atoms, and wherein the oxyalkylated hydrocarbyl phenol is substantially free of aromatic hydrocarbyl groups. The invention further relates to a method of lubricating a mechanical device (such as an internal combustion engine) with the lubricating composition. The invention further relates to the use of the oxyalkylated hydrocarbyl phenol in the lubricating composition to a passenger car internal combustion engine at least one of (i) control of fuel economy, (ii) control of corrosion, (iii) cleanliness, and (iv) control of bore wear.

The present disclosure relates to emulsifying agents produced from succinic acids or anhydrides and polyalkylene glycols. The present disclosure also relates to lubricating oils containing such emulsifying agents. The emulsifying agent provides a lubricating oil that is substantially free of an aqueous layer after about 24 hours when tested according to ASTM D7563-10.

The invention relates an additive composition for a drilling fluid, as well as a method of increasing the lubricity and reducing the coefficient of friction of a drilling fluid. The additive composition may further contain a sulfurized olefin and/or a metal dithiophosphate compound, which further enhances the lubricating effect.

A method for improving fuel efficiency and reducing frictional properties while maintaining or improving deposit control, in an engine lubricated with a lubricating oil.

A method and composition for reducing a coefficient of friction are disclosed. In an embodiment, a method for reducing a coefficient of friction between two surfaces in a borehole includes preparing a mixture comprising a primary lubricating agent, a primary surfactant, a spreading agent, and an aqueous fluid. The method also includes pumping the mixture into the borehole such that the mixture contacts the two surfaces and reduces the coefficient of friction for the two surfaces.
