What type of oil is best for the GN motor?

So your running amsoil. Any leaks with the amsoil. What did you notice different from the change? I have a friend that stock car races and swears by amsoil. When they started using it they would tare down the motor mid season. They don't need to do it anymore because of the amsoil. I have been contiplating running it but dont want oil leaks.

I started using amsoil about 7 months ago. I noticed the motor was a lot quieter, especially on cold starts. Also when I change the oil it still looks like good oil rather than all black like regular oil. Actually my car leaks less now, I dont know why though. It used to drip about 3-5 drops over night now it is 1-2 drops. Dont know if it is from the oil or not.
