Abstract
A method is disclosed for improving the thickener yield in soap thickened polyalphaolefin base oil greases comprising the steps of (a) producing a simple or complex soap thickener in a quantity of a first PAO of viscosity lower than that of the base oil component in the final grease composition to produce a thickened PAO and (b) adding to the thickened PAO a quantity of a second PAO of viscosity higher than that desired of the base oil component in the final grease composition sufficient to produce a final grease product having the desired base oil viscosity.
