Abstract
Methods are provided for characterizing crude oils, crude fractions, or other potential feedstocks for forming lubricating base oils in order to determine the suitability of a feedstock for lubricating base oil production. One type of characterization is to determine the isoparaffin, naphthene, and/or aromatics contents of the distillate portion of a feedstock. A second characterization is to determine the viscosity index of a distillate portion of a feedstock after dewaxing the distillate portion to a target pour point.
