I've started using 5w-40 as it's able to deal with higher engine temperatures seen on turbo charged engines (if I'm correct). If you like to use the full rev range, perhaps 5w-40 would be better long term, but otherwise there's little, if any, different at standard tune.

Correct me if I'm wrong though, I only know the real basics.
