The first first brim-to-brim on my 640i gave me 32.9 mpg (UK Imp gals) on a trip of 430 miles, with the OBC indicating 33.2, so there's no significant discrepancy between indicated and actual.
Granted, the trip was mostly on Motorways and fast A roads, but I spent a good deal of time snarled up in traffic jams on the M25 and M1.
I'll be more than happy to average 27ish in the long term.
