Lol. If you are enjoying the car, mpg should be like at 16mpg.

Day to day I just drive it in D2 and whatever it chooses to shift in that mode.

MPG read out is 21.3 however, hand calculations after fill-up only yield 20.1.

Thanks. However:
Tried a re-set. Didn't fix it. Also I'm showing "MAX" Oil, but I don't believe that either. Visiting the dealer tomorrow morning. It'll be sad to lose this 99.9 MPG capability!

My car displayed 22.4 mpg when I did a pure highway run. Went 312 miles before I filled up again.

So yes, it is possible.
