I don't know who came up with this myth about 80 using so much more than 60, it just isn't true!! I tried not going above 65 for a tank, made no difference to sitting at 80/90!
Weirdly, 75 (70 on sat nav) seems to be more efficient than 65 just going off the instant mpg, I have wondered if there's something in the map that makes a genuine 70mph cruise as efficient as possible - as presumably they test MPG and emmisions on actual speed rather than the clock speed. But maybe I've just imagined it, either way I don't waste time and cause myself stress cruising at 60 any more lol.
