ABSTRACT:
A composition of white oil having a kinematic viscosity at 100° C. between about 1.5 cSt and 36 cSt, a viscosity index greater than an amount calculated by the equation: Viscosity Index=28×Ln(the Kinematic Viscosity at 100° C.)+105, less than 18 weight percent of molecules with cycloparaffin functionality, a pour point less than zero degrees C., and a Saybolt color of +20 or greater. Also, a composition of white oil having a kinematic viscosity at 100° C. between about 1.5 cSt and 36 cSt, a viscosity index greater than an amount calculated by the equation: Viscosity Index=28×Ln(the Kinematic Viscosity at 100° C.)+95, between 5 and less than 18 weight percent of molecules with cycloparaffin functionality, less than 1.2 weight percent molecules with multicycloparaffin functionality, a pour point less than zero degrees C., and a Saybolt color of +20 or greater.
