On motorways or long journey in 5th gear its surpisingly economical. If your mostly doing town driving it drinks petrol like its going out of fashion. My long term average for about town is about 25mpg. For a recent 150 mile journey on a nice open road it was 42mpg. All in fifth gear and at a steady 60ish (boring I know) but I was pleasantly surprised how economical it could be, all that low down torque means it was pretty much like driving an automatic.
