2 WD Last weekend I got 26.1 on a trip down to the Texas coast 175 miles half at 74 mph half at 80-85 mph. Just got this 2010 with 45000 miles a week ago. It is an awesome machine. I passed more people on the way home like they were going in reverse when I flew by at over 100. We only got 23.1 coming home. I bought this car for my wife and after this weekend she's probably NOT going to let me drive it much anymore. (I drive too fast) That's OK cause I don't let her drive my 2017 F150 Coyote V8 Fx4 which I USED to think was fast. Not anymore. This G37 is flawless. I had no idea....
Shocked with my improvement in fuel economy from winter to spring. I've got a '13 x sedan w/ 77k miles. I was averaging about 22mpg in the winter and jumped up to over 25mpg after taking the snow tires off and driving in warmer temps.
Mostly back country roads, no stop and go, 40-65 mph. Never afraid to go WOT.
A lot of Metro areas switch to winter gas in the, well, winter. Higher ethanol content to increase vapor pressure for easier starting. Ethanol has lower heating value than gasoline so more fuel must be injected to make the same power.

Are you near Boston?
Very interesting I did not know that. I live about 1.5 hrs from Boston in small town southern New Hampshire. I'm not sure if that is the case at the stations that I fill up at, because my previous car, '06 TSX, had a heck of a time starting in below zero temps. The G has no problems in cold.
I get about 12 MPG in city stop and go driving. I stomp on it occasionally, though generally I don't "race from stoplight to stoplight." But even when I tried to drive the most conservative, mileage-conscious style I still got about 12 MPG. But you know I don't drive much- about 1,500 to 2,000 miles a year so even this poor mileage doesn't cost all that much money- I fill up about every 3~4 weeks, so about $1,100 a year for gas. I enjoy the car a lot. To me the extra $700 a year for gas over a Honda is worth it.
High twenties on the freeway at 70 MPH cruise, but I'm only on the highway three or four times a year.
Since 2010 when I got my g37x new, I've been getting the following milage under different conditions:
a) First 5 years: 22.3 mpg; mostly long freeway or mountain road trips, with maybe 15% urban driving.
b) Past 3 years: 18.6 mpg; 85% suburban driving, average 35mph.
I don't do enough highway driving to find the sweet spot where I get the best fuel economy, @ 74 on the speedo it's typically around 26.3 and in town 13.5 - 14.5.
Yesterday I was on a stretch of I80 from DSM to CR and computer said 27.9 - it's usually very close to a manual calculation. Around 90 degrees, cruise set at 78, however car said 73.7 so I need to check with smartphone GPS app, RPM @ 2,500. I reset the MPG at speed and this was after +/- 75 miles so I would assume accurate.
I'm getting between 11 and 12 mpg in town, which is 90% of my travel. That's not very good mileage, but I'm OK with it. I drive about 3,500 a year. about 2,800 of that is city driving. So, roughly, driving my 2013 G37x costs me about $450 more a year vs. a car that would get 20 MPG in town.
I am averaging 17ish MPG in my G37x. Car is usually a Sunday driver with an occasional road trip. I averaged 18ish in the G25x I traded in. I drive mebbe 3K miles a year with lots of steep hills. Downtown (and now freeway) traffic will experience stop and go. I like using sport mode uphill to avoid gear hunting. I use K&N drop ins and switch out ice & snow tires for summer tires.
