  • Publication number: 20040154957
    Abstract: This invention relates to lubricants comprising 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 novel high viscosity index, low-viscosity lubricants usable as wide-temperature lubricants, for example hyrdraulic oils, comprising novel low-viscosity base stocks, with improved performance in low-temperature viscosity, and methods to produce them.
