G37S 6MT, Both center gauge LED and 7" TFT mileage estimates have put me at between 19 and 23, averaging 21 with 70% side roads and 30% highway.
But, at 2nd tank fill up, I did the simple old school (total miles - total miles at 1st fill up)/gallons to completely full calculation and from that I got an average of 26 mpg!
I'm still under 1000 miles and taking it quite easy, but I was quite shocked at how inaccurate both the onboard fuel efficiency estimates are. I suspected the LED mileage calculator might be too stupid to properly consider speed of travel but I expected the Nav screen TFT mileage estimates to be a lot smarter. I should hook up my old pocket PC to the OBD on this thing and see what that calculates.
