Over the last 10-12 years I've had 4 BMW 7 series. Petrol and diesel.
Petrol got 22-26 mpg.

You didn't do much town/heavy traffic driving then?

Dailty commute is a mixture of 20% A roads balance city, The motorway bit is just like city driving due to nose to tail stop start traffice most of the way.

With petrol on a long journey with extreme economy style driving I could get 26-28mpg but it was too painful. With diesel self imposed economy type driving produces very little difference over the computers economy style, (I can select economy style from the computer programme instead of comfort, extra comfort, sport or madness)
