FWIW, I am getting better gas mileage in my Audi 2.8 with Pennzoil 5w-50 than any 30w or 40w synthetic I've tried. I believe the thicker oil is giving a better ring seal, and cuts down on blow-by.
Quick update on using GC 0w-30 in an Audi 3.2 FSI

If you want to try Pennzoil in an Audi, Pennzoil Platinum 5w-40 Euro Formula would be the one to use, alas, this product seems to be next to impossible to find anywhere but on paper.
Ultra is clearly an American and Asian oil.....period, end of story. It dreams of being a 3.5 HTHS oil.....not happening.

I would look for Rl_RS4 's posts on audi forums such as fortitude. If you pm him on one of those forums or BITOG he may be able to tell you more specifics about the 3.2 V6. Make sure to ask him about more oils than just Renewable Lubricants Biosyn.
I would guess that many of the same issues (primarily fuel dilution and valve deposits from the PCV) apply similarly to the 2.0 FSI and the 3.2 FSI V6. But I haven't studied the 3.2 V6 UOAs or the engine.
saaber1 have you opened you IM yet, just curious if you PCV mod is preventing carbon build up?
I have feeling that some of it might be due to the valve overlap simulating EGR function..
