  • Patent number: 8318001
    Abstract: We provide a base oil comprising hydrocarbons with consecutive numbers of carbon atoms. The base oil has a boiling range from 700 to 925° F. (371 to 496° C.), a VI from 105 to 119, and either a Noack volatility less than 18 wt % or a CCS VIS at ?25° C. less than 1500 mPa·s. The base oil may have a ratio of Noack Volatility to CCS VIS at ?25° C. multiplied by 100 from 0.80 to 1.55.

  • Publication number: 20100078353
    Abstract: A process to manufacture a base oil, comprising selecting an original base oil having an original VI, an original volatility, and an original CCS VIS; and removing a lower boiling fraction, whereby the base oil is made having a kinematic viscosity at 100° C. from 4.2 to 4.6 mm2/s, a VI that is at least 4 higher than the original VI, a volatility that is at least 3 wt % lower than the original volatility, and a CCS VIS that is within 200 mPa·s of the original CCS VIS. A process to manufacture a base oil, comprising selecting an original base oil and removing a lower boiling fraction from the original base oil, whereby the base oil has a ratio of a Noack Volatility to a CCS VIS at ?25° C. multiplied by 100 from 0.80 to 1.55. Also a base oil, made by the processes disclosed herein.

  • Publication number: 20100077842
    Abstract: A method for predicting a property of a base oil, and a blend chart, are provided. The method for predicting a property of a base oil includes selecting two base stocks, and preparing a chart having the viscometric property under low temperature and the volatility of both base stocks and curves between them that is used to predict whether blends of two base stocks will meet requirements for a finished lubricant.
