Jake and Charles have witnessed way too much damage from lack of proper lubrication on motors using exclusively Mobil 1. Though they will not recommend an oil (too much flack) I have read users recommending Castrol Full Synthetic 5W/40. I also hear Swepco would be an excellent alternative.
My Porsche tuner highly recommends Royal Purple.
