I run Napa/Valvoline in my rigs with Wal-Mart Motorcraft filters. I tried Motorcraft oil in my F-150 once, the engine was mechanically louder so I went back. I have about 54k and so far so good.

A lot of professionals, factory reps, oil analysis experts etc. over there. Mobil 1 isn't very highly regarded. Recently Pennzoil Platinum has been suggested by many as the way to go for on-the-shelf synthetics. Of course there is Amsoil, Schaffers etc. but as far as stuff you can get anywhere it's the best right now
