My car is about a week old and I have 300 miles on it. I'm getting 16.2 MPG.

Almost all city driving. And any highway driving I do is during heavy traffic.

I am honestly getting 24.4 in mixed driving. Put on a pair of K & N drop ins and got 2 more mpg to 24.4.

I average 19.4 with probably 60/40 in favor of city driving with 18 gallons of gas. I took a trip to Santa Barbara the other weekend and drove 410 miles on 18 gallons. Probably a 90/10 in favor of highway and I was doing probably average of 80 the whole time. Once I was there I drove through the city every day. Honestly not bad at all for my baby.

08 G37S - did a straight highway trip, avg. speed from 71 - 79 mph (mostly); got about 24 - 26 mpg. I didn't finish the tank off, but I added my estimated remaining mileage and my tripmeter and it was 512 miles total. I did make a quick stop in a rural town area and I did hit 90 for a few minutes during the trip as well.

Just a request - can folks with superchargers or turbos please post their MPG feedback? Thanks!

I think the newer G's are getting better mpg. I just drove 306 miles at average 72.4 mph & got 24.6 mpg & ran up over 110 mph when I could get away with it.

155 miles on the odemeter and took a quick 50 mile highway trip today...at 65-70 mph was averaging at staggering 29-31. I was shocked...and in a good way.

Bone stock at the moment...
