Real word gas mileage?

I just drove my neighbors F10 M5 (he is still sub 1200 miles, so not past the break in) and was very surprised to see that after 500 miles of mostly tame city driving he was getting 12.3 mpg.

What other "real word" mpg numbers are folks getting, and does it improve after the break-in service? The car is rated for 17/22 and some folks have reported 28 on the freeway. But 12.3mpg of non-spirited driving seems really low.

Trying to do my ED in April...
