Use any synthetic and you'll be alright.
Royal purple and amsoil are mad expensive, but better quality. Basically more resistant to breakdown, more or better quality detergants to clean up and neutralize deposits, and more slippery.
You'll probably see 2 more horsepower on a dyno compared to a conventional synthetic.
