Abstract

A base oil slate comprising three or more base oil grades having kinematic viscosities at 100° C. between about 1.8 cSt and about 30 cSt prepared from a waxy feed wherein each of the base oil grades is a base oil blend which comprises: (a) between about 0.1 wt. % and about 99.9 wt. % of a distillation fraction prepared in light block mode operation; and (b) between about 0.1 wt. % and about 99.9 wt. % of a distillation fraction prepared in medium block mode operation. Also, a base oil slate prepared from a waxy feed, said product slate comprising 3 or more base oil grades, each base oil grade having a kinematic viscosity at 100° C. between about 1.8 cSt and about 30 cSt and a VI greater than an amount defined by the equation VI=Ln(Vis100, in cSt)+95, wherein Ln(Vis100, in cSt) is the natural log of the kinematic viscosity at 100° C.
