Pick a route, and start with a full tank, and then fill up again, and record gallons used over miles driven, and compare that number to the MPG gauge.

wow, that thread is from 2011. I didn't even realize it until I got towards the end.

I can get 33mpg at 55mph with cruise control on. The gauge is pretty accurate as well. Should be interesting to see what people get in the 2015's
