I use Castrol in mine and ive always liked it. the shop i work for is also a large Castrol and Amsoil shop. Either is great in my books. i have used RP in the past and i was never really sold on it. still a good choice mind you but i cant justify spending the extra cash on it. i find Castrol Syntec does the same job but a little better.
