A lubricating composition includes an oil of lubricating viscosity and a compound comprising a protected mercaptophenol. The protected mercaptophenol includes a mercapto group in which the hydrogen is substituted with a substituent of at least 5 carbons. The substituent is selected from hydroxy-substituted hydrocarbyl groups, poly(ether) groups, hydrocarbyl groups, and mixtures and salts thereof.

A solid-state lubricant composition is disclosed. The solid-lubricant contains graphene, an oxide of a metal, and one or more polymeric binders. A method of making a solid-state lubricant coating on various substrates is disclosed. The method includes the steps of making a homogeneous slurry comprising powder of an oxide of a metal, graphene, and a polymeric binder with organic volatile solvent; coating a substrate with the homogeneous slurry with desired thicknesses; and drying the slurry on the substrate naturally or applying additional heat, resulting in a solid lubricant coating on the substrate. Substrates with coated solid composite lubricant show wear reduction and lower coefficient of friction compared with uncoated substrates.

The present invention provides a process for in situ synthesis of dispersion of ZnO and TiO.sub.2 nanoparticles in an oil medium, wherein the process comprises: (a) providing layered basic zinc hydroxide (LBZ) in an oil medium, containing a dispersant, (b) providing a titanium precursor in the oil medium to obtain a mixture, (c) hydrolyzing the mixture to obtain a suspension, and (d) decomposing the suspension to obtain a dispersion of mixture of ZnO and TiO.sub.2 nanoparticles. The present invention also provides an oil dispersion comprising dispersant stabilized mixture of zinc oxide and titanium dioxide nanoparticles were synthesized through this process. The dispersion contains up to 2.5 Wt % metals loading balanced with dispersant and base oil or dispersant alone. Addition of this dispersion to oil of lubricating viscosity improves the anti-wear property and resulting a low SAPS formulation.
