Are your fuel bills higher than you expected? Help us find out the truth behind official fuel consumption figures.
What Car? and Lex Vehicle Leasing have joined forces on a project to see how close, or how far, your car is from its official fuel consumption figure.
Be part of the team
We want volunteers to join the team and tell us how much fuel, and cash, they're getting through in the real world of everyday motoring.
It doesn't matter what car you drive, but you'll need to fill up at least once a week in order for us to collect useable data from the two-month trial.
Just send us an email and we'll reply with a fuel log to keep in your car. All you have to do is fill in the details every time you brim your tank.
E-mail firstname.lastname@example.org and help us put the official figures to the test.
