Abstract: A premium synthetic lubricant having antiwear properties comprises a synthetic isoparaffinic hydrocarbon base stock and an effective amount of at least one antiwear additive. The antiwear additive is preferably at least one of a metal phosphate, a metal dialkyldithiophosphate, a metal dithiophosphate a metal thiocarbamate, a metal dithiocarbamate, an ethoxylated amine dialkyldithiophosphate and an ethoxylated amine dithiobenzoate. Metal dialkyldithiophosphates are preferred, particularly zincdialkyldithiophosphate (ZDDP). The base stock is derived from a waxy, Fischer-Tropsch synthesized hydrocarbon feed fraction comprising hydrocarbons having an initial boiling point in the range of about 650-750.degree. F., by a process which comprises hydroisomerizing the feed and dewaxing the isomerate. The lubricant may also contain hydrocarbonaceous and synthetic base stock material in admxture with the Fischer-Tropsch derived base stock.

Abstract: 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.
