[QUOTE="jimdawg185, post: 1415095, member: 757"] I sell the oil lots of these guy on here are raving about. But if it was up between the Schaffer's and the Motor craft, Schaffer's should out perform it. Our oil makes motorcraft look bad, and Schaffer is probably the closest I've seen to ours on the market, at least in these engines. Just my two cents. Sent from my iPhone using Tapatalk [/QUOTE]
