If the mpg calculator is ANYTHING like the 05-09, they all behave differently. Best thing is to hand calculate for a few hundred or even thousand miles and compare it with the computer to see what the relationship is.

Yours may be 2 MPG low, but someone else maybe 1 low, or even 1 or 2 high.

I through that out there so others might watch that too, thanks.

I can count on the mpg display being 0.5MPG too low. I have seen it off as much as 2.5MPG. It seems the harder you are on the car, the bigger the difference becomes. After going 369 miles, my computer told me I got 25.8MPG, but in reality got 27.4. I've never seen one so far off before.
