Patent ID: 7572361

Claim:
A lubricant blend comprising: a. from about 10 to about 80 weight percent based upon the total lubricant blend of a lubricant base oil fraction derived from highly paraffinic wax having a viscosity of between about 2 cSt and 20 cSt at 100° C., wherein the lubricant base oil fraction derived from highly paraffinic wax comprises: (i) less than 0.30 weight percent aromatics; (ii) greater than 5 weight percent molecules with cycloparaffinic functionality; and (iii) a ratio of weight percent of molecules with monocycloparaffinic functionality to weight percent of molecules with multicycloparaffinic functionality greater than 15; b. from about 20 to about 90 weight percent based upon the total lubricant blend of a petroleum derived base oil selected from the group consisting of a Group II base oil, a Group III base oil, and mixtures thereof; and c. from about 0.01 to 12 weight percent based upon the total lubricant blend of a pour point depressant; wherein the lubricant blend has a viscosity of about 3 cSt or greater at 100° C. and a Brookfield viscosity at −40° C. of less than 100,000 cP.
