Actually the parts guy's making none of those claims. He said some of his customers reported those experiences. He shrugged and said, "I don't know" when asked if that made a lot of sense to him. I've used Jetron in my 6.3 (PO and both shops who've done work on the beast recommend that product) so am somewhat positively disposed to these products. Lubro Moly is from a German manufacturer. One of many sites with information:

I'm not shilling for these cats, but here's a product run down on the motor oils:

Believe me, I have no interest in opennig up the "which oil is better?" discussion. I was just curious if anyone else had decided to use the motor oil.
Ciao for now
