Patent ID: 8342217

Claim:
A lubricant composition, comprising: a polyoxyalkene as a lubricating agent; between 4 wt. % and 7.5 wt. % of silica as a thickening agent; no more than 1% water; and between 300 ppm and 2 wt. % of an inorganic thixotropic-enhancing metal oxide, wherein a metal component of the thixotropic-enhancing metal oxide is selected from alkali metals, alkaline earth metals, iron, cobalt, nickel, copper, aluminum or combinations thereof, wherein the lubricant composition viscosity is between 10 Pa-s and 60 Pa-s measured at 20° C. with a shear rate of 10 s −1 , and wherein the inorganic thixotropic-enhancing metal oxide provides an increase in a recovered threshold stress value TS2 of the lubricant composition to at least about 90% of the initial threshold stress value TS1.
