  • Publication number: 20070142250
    Abstract: A lubricating oil (made from Group III base oil having a sequential number of carbon atoms) having a VI between 155 and 300, a RPVOT greater than 680 minutes, and a kinematic viscosity at 40° C. from 19.8 cSt to 748 cSt. A lubricating oil having a high VI and high RPVOT comprising: a) a Group III base oil with a sequential number of carbon atoms, and defined cycloparaffin composition or low traction coefficient, b) an antioxidant additive concentrate and c) no VI improver. A process comprising: a) hydroisomerization dewaxing of a waxy feed, b) fractionating the produced base oil, c) selecting a fraction having a VI greater than 150, and a high level of molecules with cycloparaffinic functionality or a low traction coefficient, and d) blending the fraction with an antioxidant additive concentrate. Also, a method of improving the oxidation stability of a lubricating oil.

  • 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.
