No interest in Auto Rx yet... its a tad steep; so, I'll run a couple of 3k OCI's till I'm satisfied, and then put 6 qts. of PP, M1 o-40, Royal Purple, or hark... Motul! I'm hot for Motul now; so I'll see what everyone thinks. But for now, I want to clean it out real good with whatever's easily available off the shelf.
Thanks for asking.
