A lubricity enhancer at extreme temperatures and pressures comprises a first stage solid lubricant selected from the group consisting of molybdenum disulfide, graphite, polytetrafluorethylene and mixtures thereof, a second stage solid lubricant selected from the group consisting of boron nitride, tungsten disulfide and mixtures thereof, and a third stage solid lubricant of an inorganic fluoride characterized by being capable of forming a bonded substantially homogeneous film on a substrate at the elevated temperatures and pressures. The solid lubricants are blended in a concentrated form with a liquid carrier to form a lubricant additive concentrate for addition to a base oil or the solid lubricants are blended directly with the base oil to form a lubricating composition.
