Claim Text:
1. A process for improving MRV performance and decreasing wax crystallization in a lubricating oil comprising: a) obtaining a first base oil comprising: at least about 55 wt % of molecules having paraffinic functionality, at least about 25 wt % of molecules having cycloparaffinic functionality, a ratio of weight percent molecules with paraffinic functionality to weight percent of molecules with cycloparaffinic functionality of about 2, a boiling range between about 359 to 490° C., a VI between about 96 to 106, a flash point between about 190 to 228° C., a kinematic viscosity between about 3.0 to 7.0 cSt at 100° C., and a kinematic viscosity between about 24 to 34 cSt at 40° C.; and b) blending a second base oil comprising a Group II base oil with the first base oil obtained in Step (a) to provide a base oil blend comprising from about 5 to about 60 wt % of the second base oil, wherein the first base oil is a Group I base oil.
