Hi all, we bought a 1.2 lounge in november it is 6 months old and done 3000 miles. The problem is it will not go above 38 mpg where as before we had a 2010 1.2 easy that never went below 43 mpg has anyone else had this problem or know what to do to improve this.it dos not seem to have a lot of get up and go and doesn't seem to tick over smoothly. Any help please.
