A method for improving the lubricating properties of a isomerized
distillate base oil having a kinematic viscosity at 100 degrees C.
between about 2.5 cSt and about 8 cSt, the method comprising blending
with said isomerized distillate base oil a sufficient amount of a pour
point depressing base oil blending component to reduce the pour point of
the resulting base oil blend at least 3 degrees C. below the pour point
of the distillate base oil wherein the pour point depressing base oil
blending component is an isomerized petroleum derived base oil containing
material having a boiling range above about 1050 degrees F.; also
lubricating base oil blends prepared according to the process; and the
pour point depressing base oil blending component.
