Abstract
Provided are lube base stocks produced from renewable biological sources with improved low temperature properties. In one form, the lube base stock includes from 10 to 35 wt. % paraffins, 40 to 70 wt. % 1-ring naphthenes, and 0 to 40 wt. % combined 2-ring naphthenes and aromatics, and has a ratio of 1-ring naphthenes to paraffins from 1.8 to 5.0, and a Viscosity Index of from 100 to 160. The lube base stock has aC level ranging from 2 to 101% of the modern dayC level in the atmosphere, and yields a CCS ratio (Cold Crank Simulator (CCS) viscosity to the predicted CCS viscosity by Walther equation) of less than or equal to 0.85 at −35° C. The base stocks are useful as in formulated lubricant compositions requiring improved low temperature properties.
