I would say mid 40's (maybe a little lower) sounds about right for those kind of speeds. I've done a 300 mile round trip with bits of town driving at each end and a constant 70-75 on the motorway and seen 47 odd according to the OBC. Did the entire trip in half a tank according to the gauge, though there was also whatever was in the filler neck (I properly brimmed it and when I started the journey the gauge was off the top end of the scale a little bit!), so that's about 33litres I reckon.
