Summary:PROBLEM TO BE SOLVED: To provide a process for producing a lubricating oil basestock having at least 90 wt.% saturates and a VI of at least 105. SOLUTION: The process for producing the lubricating oil basestock includes selectively hydroconverting a raffinate from a solvent extraction zone in a two step hydroconversion zone followed by a hydrofinishing zone.
