Default what brand of oil do you run?

I just did a oil analysis on my car. i run Mobil 1 synthetic.

I am looking for something more slick to wear the bearings less. Is Castrol Edge any better?

Amsoil here. Pennzoil Plat. and Mobile 1 extended performance seem to be good also.

All of my best oil analyses have been with German Castrol.

I can't find any GC here in hawaii, maybe not looking hard enough. I was a loyal M1 user for the last 5 years in my bmw and every other car i've owned until recently trying PP in the truck, I am now a converted Pennzoil Platinum user.

I usually use Terry's service. Be advised that he recently raised the price.

AMSOIL! I have been using it for years! Seen dramatic results over and over! from trucks, my WS6 and boats. I had to become a dealer for it! But thats my opinion. I wish I had pics of my LS1 when I took it apart for upgrades. had a 120k and was immaculate inside. kinda freaky how clean it was. lol I'm sold on it.
