I'm with you, Husk man...I've used Amsoil in my work truck (95 dodge cummins diesel) stem to stern too, with the BIG bypass filter as well. I just drove her to San Diego today, I'm at 484,500 miles and running perfect. Original u joints!
I'm using lubrimoly (german product) full synth in my 560 sel, but when not I'll go Amsoil.
