ABSTRACT:
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.
