ABSTRACT:
The present invention provides lubricant mixtures for use as base fluid in bearing grease comprising 25 to 90 percent w/w of a liquid ester having a viscosity at 40.degree. C. in the range 100 to 200 mm.sup.2 /s, and 75 to 10 percent w/w of a liquid poly-.alpha.-olefin having a viscosity at 100.degree. C. in the range 2 to 10 mm.sup.2 /s, and bearing grease compositions containing a major proportion of such lubricant mixtures, particularly such compositions containing a clay thickener.
