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°F+ dewaxate. The waxy feed has an initial boiling point in the range of about 650-750°F, from which it continuously boils up to at least 1050°F and has a T 90 -T 10 temperature difference of at least 350°F. The feed is preferably hydroisomerized without any pretreatment, other than optional fractionation. The 650-750°F+ dewaxate is fractionated into two or more base stocks of different viscosity.

Abstract: Premium synthetic lubricants comprise a synthetic isoparaffinic hydrocarbon base stock and an effective amount of at least one, and typically a plurality of lubricant additives such as a detergent, dispersant, antioxidant, antiwear additive, pout point depresant, VI improver and the like. The base stock is derived from a waxy, paraffinic, Fischer-Tropsch synthesized hydrocarbon feed fraction having an initial boiling point in the range of about 650-750° F. and continuously boiling up to at least 1050° F., by a process which comprises hydroisomerizing the feed and dewaxing the isomerate. The waxy feed has a T90-T10 temperature difference of at least 350° F. and is preferably hydroisomerized without any pretreatment, other than optional fractionation. The lubricant may also contain hydrocarbonaceous and synthetic base stock material. Lubricants, such as fully formulated multigrade automotive crankcase and transmission oils formed by adding a suitable additive package to the isoparaffinic base stock have exhibited performance superior to similar fully formulated oils based on both PAO and conventional, petroleum derived base stocks.

Abstract: A wax-containing middle distillate, such as diesel fuel, having improved low temperature flow properties comprises three or more components including (A) an oil-soluble ethylene backbone flow improving polymer such as ethylene vinyl acetate copolymer, (B) a hydrocarbyl substituted amine salt and/or amide of a carboxylic acid or anhydride such as phthalic anhydride salts, and (C) a hydrocarbyl substituted amine salt and/or amide of (I) a benzoic acid derivative such as the dihydrogenated tallow amine salt of an alkyl substituted dithiobenzoic acid or (II) a phosphoric acid derivative such as the dihydrogenated tallow amine salt of dialkyldithiophosphoric acid.

Abstract: A lubricating composition having improved anti-wear properties comprises: A. a lubricating oil basestock; B. a metal phosphate; C. a metal carbamate; and D. an alkyl hydroxy-aryl sulfide. The metal phosphate is preferably a dialkylphosphate, zinc compounds being especially suitable. From about 0.1 to about 1.0 wt.% (based on the basestock) is preferred. The metal carbamate is preferably a dithiocarbamate, more especially zinc compounds. From about 0.1 to about 1.3 wt.% is preferred. The sulfide is preferably an alkyl phenol sulfide, for example, nonyl phenol sulfide. From about 0.2 to about 2 wt.% is preferred.
