Mobil One Synthetic 10W30. On other cars I have run other synthetic oils and found that Mobil one has kept things the cleanest on my engine. Besides Endurance Sports cars use it, why use something that is not used by those guys?

Use Mobil 1 5W30. Don't want to hijack the thread, but I was told to use the "Yellow" top bottle of oil instead of the gray top bottle. The bottle with the yellow top has a zinc additive which "performs" better in the car. Don't know if true or not.

AMSOIL 10w-40
I've noticed that one grade thicker makes the engine a little quieter. (lifter noise)
I've seen oil analysis tests (huge thread on www.ls1tech) and I'd NEVER use Mobil again after seeing the independent results.
(and no I don't remember the details, it was years ago)
Castrol Syntec, Royal Purple, Redline would be my other choices if AMSOIL wasn't around.
