Provided are lubricant compositions from renewable biological sources with improved properties and methods of making and using such compositions. In one form, the lubricant composition includes from 20 to 99.8 wt. % of a lube base stock produced from a renewable biological source and an effective amount of one or more lubricant additives. The lube base stock includes 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 a 14C level ranging from 2 to 101% of the modern day 14C level in the atmosphere, and yields a CCS ratio of less than or equal to 0.85 at −35° C. The lubricant compositions exhibit improved solvency and % thickening when blended with a viscosity modifier.
A lubricant composition comprising from 20 to 99.8 wt. % of a renewable lube base stock produced from a renewable biological source and an effective amount of one or more lubricant additives, wherein the renewable 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, wherein the Free Carbon Index is less than 3.0, wherein pendant methyl groups mole % is less than or equal to 4.33, wherein the ratio of 1-ring naphthenes to paraffins is from 1.8 to 5.0 for the renewable lube base stock, and wherein the Viscosity Index of the renewable lube base stock is from 100 to 160.
A lubricant composition comprising from 20 to 99.8 wt. % of a renewable lube base stock produced from a renewable biological source and an effective amount of one or more lubricant additives, wherein the renewable lube base stock has a 14C level ranging from 2 to 101% of the modern day 14C level in the atmosphere, and wherein the renewable lube base stock 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., and wherein the renewable lube base stock has a Free Carbon Incex of less than 3.0 and pendant methyl groups mole % of less than or equal to 4.33.
