  • Method of Lubricating an Internal Combustion Engine
    Publication number: 20110152142
    Abstract: The invention provides a method of lubricating an internal combustion engine comprising supplying to said engine a dispersion, the dispersion comprises: (a) a metal base; (b) a surfactant; and (c) an organic medium in which the metal base is uniformly dispersed by physical processes, wherein the metal base has a mean average particle size of at least 10 nanometres to less than 1 ?m; and the dispersion has a solids content of greater than 15 wt %. The invention further provides a lubricant composition containing said dispersion.
