Just got a 2012 RWD and im not an aggressive driver at all, im getting about 30 mpg on the interstate and 20 within the city. I will add that my 04 g35x would get 22 mpg combined and slowly decline to about 19 mpg, after an oil change she was right back at 22 mpg like clock work.

12900km my car average MPG is 14 or 15 in best case :\
i think our bad gas has something to do with this poor mpg but on the bright side we pay 0.16$ per liter

Wow Telcoman those are some amazing mileage numbers. My G37xS sedan usually gets around 15 mph around town and just today got 24.8 mph on the highway. The Infiniti dealer gave me a loaner yesterday (a 2012 G37x sedan) which gave me over 28 mph. I've never gotten mileage near that good on my 09 G xS sedan although I must confess to having oversize tires on it which must hurt my mileage. I really wonder how accurate the computer is that comes up with these numbers, there seems to be so much variation between Gs.

Same Wa Wa Station
The difference in this trip was a lower morning temperature with higher humidity

Telcoman,
How do you get to the screen which shows the Fuel Economy history shown above.
I've been through the 267 page/15MB Nav manual, but cannot seem to find any instructions on how to get to this screen.
Note that I am not resetting the Nav everytime I fillup, just the odometer. I'm thinking that I should be resetting the Nav as well in order to see this screen.

In this day and age, the only cars getting below 20mpg mixed are large SUVs.
Don't give me the performance car speech because I have friends with Bimmers and Audis and those often exceed the EPA ratings on the window sticker, not fall below them. I almost wonder if this is just a limitation of large displacement, high compression, port based injection motors? Perhaps this is why the Germans like boosting their lower compression, smaller displacement, direct injection motors (of course this introduces a new set of tradeoffs).

Thanks guys. It's amazing how easy some things are to find once someone else shows you. I spent 20 mins trying to find this in the 267 page Navigation Owners Guide. Also, I noticed that I do not have any history at this point and the "Reset Fuel Eco History"button is grayed out. Is there something I need to do to engage this function?

400 miles on a 2013 G37 Sedan. So far I am at 14-15 MPG. I drive mostly on the streets, short commutes mostly and some idle time. I didn't buy it for MPG or I would of got a Prius

Have you guys doubled checked your mpg computer on the dash and navigation system for accuracy? I check my mileage by dividing how many gallons I fill by the mileage on the odometer (you would have to reset your trip monitor prior to this and make sure you fill your tank up fully) and it is consistently 1.2-2.0 miles less per mpg than the dash and the nav. I trust my manual method to the in-car computers. The closest to accurate is when you reset the dash counter every time you fill up.
Makes me wonder if these miscalculations are deliberate.
