ABSTRACT:
Novel lubricant mixtures are disclosed having unexpectedly high viscosity indices. The mixtures are blends of high viscosity index polyalphaolefins prepared with activated chromium on silica catalyst and polyalphaolefins prepared with BF3, aluminum chloride, or Ziegler-type catayst. Superior blends are also prepared from HVIXPAO with mineral oil and/or other synthetic liquid lubricants.
