I was talking with my Dad today. I began to explain to him about Ford and Hoda's more to 5W20 and the hopes they had to go through for the EPA to allow them to certify with these light oils. His eye got huge and his jaw droped. For a minute or two the color drained from his skin in disbelife. When he finaly regained his composure his exact words where " Why the He!! don't they just take the oil cap off and pi$$ in the crank case for crying out load!" Now bear in mind that he has a lot of UOA experince thank to Uncle Sam. He worked closely with FMC in developing and field testing the Bradley Fighting Vechile. He also set up the Master Gunner Program for it as well as the NET TEAM, and UCOFT program. He actualy learned all of his UOA skills while working with the Bradley. So while he is not a triboligst or a Lubrication Engineer he has a lot of real world experince. So when he said this I about fell over laughing. He thinks in terms of 600HP diesels and such so I am sure to him the idea of a 5W20 is even crazier then it is to me!
