I drove all the motorways on cruise control at 65-68mph, my town driving the week before worked out at 28.55mpg so i guessed I`d maybe get 34mpg on the long punt. Had every seat full and a bit of luggage on the way down, and one seat spare on the way back up.
Oh also had a slight drip at the fuel filter so once thats fixed I might be able to do it on ?160!
