Well 'er indoors and I over the last 7 days, have done a round trip to Portsmouth from where we live, so with the actual getting from A to B and the running around we did whilst we were there, we achieved 56 mpg (all data from Fuelly).
The car was full with our weekend going away stuff (back seat covered lol!) and boot full, and with our combined weight of 25 stone, climate control running the whole time, headlights on the whole time because of the appalling visibility through rain the whole journey and an average speed of 65mph, I don't think we did too bad really.
I'm not into this whole hypermiling thing and I trust the data put through Fuelly, so overall, I'm very happy with the figures achieved on a proper run. Car has just this morning hit 10,000 miles.
