While at Walmart today I saw a brand new display of Motorcraft Synthetic Blend 5w20 SN Rated 5 qrt jugs on the shelf . The SM version of this oil made it the "darling of the dino users" and turned in some very impressive used oil analysis . Care to predict what we may see with the new SN rated MC Syn Blend used oil analysis (i.e. improved add pack , lower wear numbers ?)
