This invention discloses a process for producing a high Viscosity Index lubricant having a viscosity of at least 125 from a waxy hydrocarbon feed having a wax content of at least 40 wt%. The process comprises catalytically dewaxing waxy paraffins present in the feed primarily by isomerization, in th...
