Someone posted a cool link where some of the best & worst oils were tested. I think the real deal Royal Purple stuff came out on top, though im not sure the Brad Penn stuff was tested.
Only question is, where to get the good stuff?
I'd like to see that, I don't remember reading it.
I think the top of the class are: Redline,Moltul,Royal Purple and Amzoil. Primarlily because they all use vegetable ester's.
I have had good luck with Mobil One for over 18 years and would never consider running a non-snythetic oil in any engine I cared about. I have run synthetic's vs conventional back to back on the dyno in at least 9 engine's. Not only did they all make more power once we switched to synthetic but the oil temp ran anywhere from 25-40 degree's cooler.( that's from lack of friction)
