The oil useage thing baffles me. I was at a truck show in Pa a few months ago. A trucker there told me he used Delvac in his KW with the Cat engine. He claimed his oil consumption dropped with the Delvac. The well known 15w40 oils are good oils, but maybe I'm wondering if the chemistry in the oils have something to do with certain engines or driving habits? I honestly don't know?
