I have the same car as you, but with stock 17" wheels. Over the two years I've had it, I've averaged around 20 mpg in Houston traffic (maybe 75% street and 25% freeway @ 60-70 mph). I keep the front at 36 psi and the rear at 40 and use premium fuel.
Could the difference in wheel size (your 20 vs my 17) increase rolling resistance and thereby reduce mileage?
I have found that if I'm in DS mode and driving at all aggressively, the mileage quickly drops to 17-18 [measured on the computer for about a half tank basis]. Since aggressive and conservative are so subjective, maybe that's in play for you...???

hey nebie21, get some 18" wheels/tires and you'll do much better. I get 9.3L/100km with my 245/40 18s.

My M5 is getting better gas mileage than that...combined driving! 
And to the OP, I got slightly over 30mpg, just highway, on my old 530....averaged around 24mpg with 65% highway.

I have a 06 530i and get only about 18 MPG with 75% city and 25% highway. It sucks, especially with the rising gas prices. I wish I could get more MPG like some of the other people on the forum.
