What are Ram HD Forum members thoughts about Amsoil Signature Series Max-Duty Synthetic Diesel Oil 10W-30? The Dealership is currently using Shell Rotella Synthetic 10W-30 on my 6.7L changes, and I guess that's pretty good stuff, too. So what's all the hype with this "Signature Series" Amsoil claiming: "6X More Wear Protection?"
