On June 30th.. just drove from S.W. Florida to Philly.. Cruise set to 77mph, most of the trip, I averaged 28.3mpg. I used 2 tanks of gas, 1st was about 465 miles took 18.5 gallons to fill, second tank 455 miles 17.5 gals to fill.. Now while here in the city I am averaging about 12mph.
When I'm home in FL, I average about 17 city and 25 hwy..
I currently have 44500 miles on the car.
Just bought my G37x last week, put some Seafoam in the tank this weekend. My commute to work 120 miles round trip.. 65-70 mph with a few WOT passing, rest of the time I manual shift keeping it 7th gear.
Came back from the PA meet this past weekend with Ahmed and got 24mpg, even after zipping down backroads in 3rd/4th gear at speeds that I cannot disclose
How the hell you guys getting 25+ MPG? is it like 90% highway?
Ill be lucky if I get more than 19..

They reset their MPG calculator while on the highway going sixty five and come in and post an average of 28. . I haven't reset mine in almost a year and it's at 19.5 mpg. Once in a while it'll jump to 21.2 mpg or so on a 60 mile trek. But, it always reverts back to 19.5 mpg.
^^ exactly.. I'm about to take mine to Kansas City for the Seahawks game Saturday, I'll see what I get from about 320 miles round trip. In a perfect world, I would use less than an entire tank.
My very first tank was about 60% highway and 40% city. Hit about 21 mpg. My next tank is about 40% highway and 60% city, currently getting 18 mpg.
I'm actually glad the transmission has granny shifts because it does save some gas...my mpg would be way lower. As it is, I include a few good WOT passes almost each day, hard not to!

Had my 2011 for 2 weeks. First 230 mile round trip showed 25.4 mpg. The first 115 was 23.9mpg at 75 to 80 mph. The return 115 was at 65 to 70 mph. To bring the overall 230 miles to 25.4mpg, I figured the return trip was 26.9. This was all on the built in Trip info. I'll be interested in what my actual gallons will be at fill up, for the 230 miles.
