Abstract

This invention is directed to a lubricant composition that is comprised of a continuous phase and a discontinuous phase, i.e., a two phase lubricant composition. The continuous phase and the discontinuous phase of the lubricant of this invention are oil or oil type compositions that are essentially insoluble in one another. The lubricant composition is comprised of a continuous phase base oil that is comprised of a low viscosity Group II, III, IV or GTL base stock or a blend of at least two of the Group II, III, IV and GTL base stocks, optionally including a low viscosity Group V base stock, with the continuous phase base oil having, independently, a viscosity of from 1 to 100 cSt at 100° C. The lubricant composition is further comprised of a discontinuous phase that is comprised of an ester composition having a mean average droplet size of from 0.01 microns to 20 microns, in which the ester composition is comprised of an ester compound having no ether linkages.
