A premium synthetic lubricating oil base stock having a high VI and low pour point is made by hydroisomerizing a Fischer-Tropsch synthesized waxy, paraffinic feed wax and then dewaxing the hydroisomerate to form a 650-750.degree. F.+ dewaxate. The waxy feed has an initial boiling point in the range of about 650-750.degree. F., from which it continuously boils up to at least 1050.degree. F. and has a T.sub.90 -T.sub.10 temperature difference of at least 350.degree. F. The feed is preferably hydroisomerized without any pretreatment, other than optional fractionation. The 650-750.degree. F.+ dewaxate is fractionated into two or more base stocks of different viscosity.
