2000 racing oil, and everything else. I've tried most of them, Rotella,
Castrol, M1, Royal Purple, etc. They all result in massive lifter tick after
drag racing and auto crossing, except for the Amsoil. The Amsoil will tick a
little bit, but it recovers very fast, and the car runs cooler on it. I've
been wanting to try Delvac, but haven't yet.
 I do have a confession though. I had an oil accumulator explode on me(guess
I should have bought the high pressure version) and the shop close by only
had Shell Rotella T 15-40? I think. To be honest, it's just as good or
better than any of the off the shelf synthetics, it's been through an auto-x
day and a night of drag racing and performed rather well.
