I have nothing but good things to say about Redline, but it's pricey. Second choice would be Mobile One, In alot of Hipo (Corvette, Porche etc..) cars from the factory and they will even void your warranty if you don't use it.
Castrol Syntec or Mobil 1. I have used both with excellent results. My Jetta had 200k miles on it with Castrol and my Sunfire is presently hitting 150k on Mobil 1. Both engine are running great and the synthetics keep the insides very clean.
I use mobil one and the inside of the engine 10 years later still looks like the day I assembled it. I've heard good things about redline also. It doesn't break down after a hard run like regular oils I've seen the difference on the oil pressure gauge.
