Just wondering what others are using and how often are you changing?

I'm using Castrol Synthetic 5W-40 and changed at first one thousand miles and will do again at 10,000 miles

Great oil comparison by the ZO6 track guys. 5W30 Pennzoil Ultra, API SM synthetic, Best wear protection and 280* before onset of thermal breakdown. It'll be what we put in ours at the 10K point.
