I have been struggling to get my fuel economy above 45mpg on this tank full, seems that I can do well round town but once on the motorway with the
CC on the mpg drops to around 40, even travelling on the flat, after 10 - 15 minutes of M'way driving it gets better, also noticed yesterday on the way back from work I had to turn off the cruise control cos some idiot pulled out in front, but when I got back up to speed and I turned it back on the the fuel economy bar chart sat at 45mpg for 5 - 6 seconds, dropped all the way to zero, sat there for a while and I then managed to get 50-55mpg all the way home, even up slight inclines. Seems to be a bit random how much fuel the cruise control uses.
Is there a knack to getting good mpg with the
CC on?
