Re: ford fiesta 1.25 zetec
Have you calculated the fuel economy based on odometer mileage and full tank of fuel (ideally using the same pump), or are you basing it on the trip computer?
Several folks have claimed the trip computer is quite inaccurate, although every time I've calculated my economy to compare against the trip computer it's been within a couple of tenths of a mpg.
