Renewable base stock from biological materials

A base stock composition comprising:

• a naphthene component in an amount of about 15 wt. % to about 30 wt. % based on a total weight of the base stock composition, wherein the naphthene component comprises a naphthene ring comprising two or more paraffinic branches covalently bonded to the naphthene ring, wherein the naphthene component has a carbon number in a range of C28 to C30;
• and
• a branched paraffinic component in an amount of about 70 wt. % to about 85 wt. % based on a total weight of the base stock composition, wherein the branched paraffinic component comprises a paraffinic backbone with a carbon number in a range of C14 to C22, wherein the branched paraffinic component comprises two or more paraffinic branches covalently bonded to the paraffinic backbone, wherein the branched paraffinic component has a carbon number in a range of C28 to C34,
• wherein the base stock composition has a kinematic viscosity at 100° C. of about 3.8 to about 4.3 cSt as measured by ASTM D 445-01,
• wherein the base stock composition has a viscosity index above 120 as measured by ASTM D2270-93, and
• wherein the base stock composition has a Noack volatility is less than about 12% as measured by ASTM D5800.

A lubricating oil composition comprising:
