This invention provides lubricant mixtures for use as base fluid in open-gear grease comprising 10% to 90% w of a liquid polybutene having a viscosity at 38 DEG C. in the range of 1,000 to 20,000 mm2/s and a viscosity at 100 DEG C. in the range of 40 to 500 mm2/s, and 10% to 90% of a liquid polyalphaolefin having a viscosity at 38 DEG C. in the range of 10 to 75 mm2/s and a viscosity at 100 DEG C. in the range of 2 to 15 mm2/s, and open-gear grease compositions containing a major proportion of such lubricant mixtures.
