  • Functional fluids having low brookfield viscosity using high viscosity-index base stocks, base oils and lubricant compositions, and methods for their production and use
    Publication number: 20040154958
    Abstract: This invention relates to base stocks and base oils that exhibit an unexpected combination of high viscosity index (130 or greater) and a ratio of measured-to-theoretical high-shear/low-temperature viscosity at −30 C. or lower and the methods of making them. Specifically, the present invention relates to low-viscosity base stocks and base oils as used in functional fluids. More specifically, the present invention relates to automatic transmission fluids showing surprising low temperature Brookfield viscosities and methods to produce them.

  • Functional fluid
    Patent number: 6426322
    Abstract: A functional fluid base oil is described comprising a mixture of (1) one or more naphthenic base stocks, and (2) one or more conventional solvent neutral base stocks and (3) one or more hydrocracked base stocks. The functional fluid base oil can be additized by the addition of one or more performance additives. The fluid is especially usefull as a power steering fluid base oil.
