Why do I see Avg MPG in my stats when I'm viewing the site in metric units?
If you're viewing Fuelly with metric units, you'll still see a reference to MPG on your car profile page. In the lower left corner under Basic Stats, you'll see the average MPG for that vehicle: We provide this as an extra statistic that might be useful, and we use this space to provide average L/100km when viewing the site in US units. Your more important average L/100km statistics are located above Basic Stats, and MPG is provided as an extra. Also keep in mind that Fuelly calculates MPG in U.S. liquid gallons, not Imperial (UK) gallons.
