Can I change my profile to show all database fuel consumptions in my preferred units? I would like to set l/100km as my default. Currently it shows MPG. BTW, is it US of Brittish MPG?
Yes! In the upper-left corner of any page you'll see three links: US | UK | Metric. You can choose one of these options and you'll see all units across the site for that preference. Here's an explanation of the differences between them: How do I view Fuelly data in metric units?
cvzyl, just go to any of your vehicles' profile page and look for a link in the bottom left of the page that says, "Get your own Fuelly badge." Click that and you'll be set from this end.
You'll have to go to whichever forum you participate in to get instructions about how to add a signature there.
