UK MPG Added
We just added support for viewing the site in Imperial MPG. If you're in the UK, you probably want this option.
Hit the UK link in the upper-left corner of any page to start viewing the site in Imperial Units. Like the Metric option, you'll still see Litres and Kilometers on car profile pages, but the fuel economy rating will be in MPG Imperial (Miles/Imperial Gallon). We call it UK MPG for brevity.
As we understand it, you can't actually buy petrol by the Imperial Gallon anymore so we don't have that as a fuel-up option. This conversion is strictly for reading the site in UK MPG.
Let us know here if you spot any problems or find a place the conversion isn't happening.
