Ok, no one will probably want to beat this, but...
I just returned from Reading to near Glasgow on one tank of fuel and that included a stoat near Heathrow.
That's right, 437.9 miles, 58.25 litres and 34.1MPG !!!!
That's measured MPG, DIS claiming it's usual bonkers amount, about 41 or so this time.
Anyone had more than that /ubbthreads/images/graemlins/smile_smoking.gif
