I also use mobil 1 extended performance synthetic exclusively in my vehicles after seeing how clean it's been coming out and clean the insides of the motors are. It also stopped burning as much, and stopped leaking on my F-150.
Previously I've used AMSOIL, Royal Purple, Valvoline Synpower, standard synthetic Mobil 1, Castrol Syntec, Castrol Edge, Pennzoil Platinum, Redline, etc.
