Interesting, we both got 56.5 mpg on the BC & 54.6 mpg or 54.27 mpg actual, looks like taking the flap out reduces your fuel consumption.simbo wrote:Just been and filled up with fuel, in the interest of science an all that, '54.27 mpg actual'. BC= 56.5.

I use Tesco's finest, 99 octane Momentum, (don't forget the points too), how about you, surely you use BP as recommended by BMW.

Been out today for a spirited ride, did 125 miles, BC = 51.3 mpg, actual 50.3 mpg.

Looks like the LC has worse fuel consumption, hasn't been posted yet.
