10W30 is a winter weight for me in the Seattle area.  Summer, I have usually
used 15W50 Mobil 1 or 20W50 synthetic blends.  Also tried Valvoline 10W40
blend.

I would.

I ran 5W30 Mobil 1 in my 5kcsq for the NW Region Steamboat event.
It's like water when you put it in!  We burnt well over a quart of it
in 2.5k miles too.

In the past, Audi's recommendations have tended towards the
heavier weights - 15W40, 20W50 for summer.  The latest (A4 1.8T
manual) said the lighter weights (5W30 maybe 10W30) were
OK if marked 'Energy Conserving'.
