Apart from the brake light switch dieing, it went really well! 30 odd degrees it never went over high 80s tanking it along the peage so can't complain!
I'm not sure to be honest, I gave up keeping tabs! I worked it out after doing 500 odd miles at 80 ish on the peage and it was about 28. I'd have got more on the way home as we used the smaller roads and sat at about 60.
