Abstract

A lubricating grease composition that is a mixture of (a) a hydrocarbon-based oil, (b) a perfluoro-polyalkyl ether oil of the formula A'--(O--CF.sub.2).sub.v --(O--C.sub.2 F.sub.4).sub.w --(O--C.sub.3 F.sub.6).sub.x --(O--C.sub.4 F.sub.8).sub.y --(O--CF.sub.2 CF(CF.sub.3)).sub.z --O--A' in which A' is --CF.sub.3, --C.sub.2 F.sub.5, --C.sub.3 F.sub.7, or --CF.sub.2 T where T is H or Cl, A' is A' or --CF.sub.3, C.sub.2 F.sub.5, --C.sub.3 F.sub.7, or --CF.sub.2 T, where T is H or Cl.sub.1 and v, w, x, y and z are whole numbers .gtoreq.0, (c) a dicarbamide as a thickening agent, (d) typical additives and (e) organic and inorganic solid lubricants. A process for the production of the lubricating grease composition is also provided.
