  • Publication number: 20080128322
    Abstract: The present invention is directed to a traction coefficient reducing lubricating oil composition comprising (a) a major amount of an oil of lubricating viscosity comprising a blend of two or more isomerized Fischer-Tropsch derived base oils wherein the kinematic viscosity of the blend is in a range from about 2 to about 14 centistokes at 100° C., and (b) one or more lubricating oil additives wherein the lubricating oil composition is essentially free of friction modifiers. The present invention is also directed to a method for reducing the traction coefficient in internal combustion engines comprising lubricating the internal combustion engines with a lubricating oil composition comprising (a) a major amount of an oil of lubricating viscosity comprising a blend of two or more isomerized Fischer-Tropsch derived base oils wherein the kinematic viscosity of the blend is in a range from about 2 to about 14 centistokes at 100° C.

  • Publication number: 20050241990
    Abstract: This invention is directed to a method of operating a wormgear drive at high energy efficiency comprising filling an oil reservoir with a wormgear lubricant comprising an isomerized Fischer-Tropsch derived distillate fraction having a low traction coefficient and operating the wormgear drive with the filled oil reservoir at an equilibrium temperature between 20 and 225 degrees C. This invention is also directed to a process for reducing the traction coefficient of a higher-traction coefficient lubricating base oil by blending it with an isomerized Fischer-Tropsch derived distillate fraction. This invention is also directed to a wormgear lubricant comprising an isomerized Fischer-Tropsch distillate fraction and between 2 and 50 weight percent thickener.

  • Publication number: 20050133407
    Abstract: A process for manufacturing a finished lubricant by: a) performing Fischer-Tropsch synthesis on syngas to provide a product stream; b) isolating from said product stream a substantially paraffinic wax feed having less than about 30 ppm total nitrogen and sulfur, and less than about 1 wt % oxygen; c) dewaxing said feed by hydroisomerization dewaxing using a shape selective intermediate pore size molecular sieve comprising a noble metal hydrogenation component, wherein the hydroisomerization temperature is between about 600° F. (315° C.) and about 750° F. (399° C.), to produce an isomerized oil; and d) hydrofinishing said isomerized oil, whereby a lubricating base oil is produced having specific desired properties; and e) blending the lubricating base oil with at least one lubricant additive.
