How smalls is your tank :S
21mpg seems to be about the average - 182 Trophy with a few mod's. The short-ish commute to/from work probably doesn't help, especially being a daily driver.
Currently getting less than 30 going back to the garage there must be a fault somewhere. Even on a motorway today at 70mph i wasn't even touching 30. Trip computer had my average speed at 15mph??!!
ahah yeah pretty much! Never going over 2K-ish in every gear, no harsh acceleration and breaking as little as possible. Pretty boring drive though!you win! how were you driving to get that? 50 in 5th??
