i keep the status screen up until i drop below 20mpg, then i just put it on music.
...fyi, my music screen is always up. i get on avg 18mpg

 

I commute 30 miles one way to work. So I am in stop and go mainly coming home. I have averaged about 22.1 mpg. I wish I could get that higher.

 

I get about 20-21mpg. I was starting to think something was wrong until I saw some of these posts. I suppose I could get better MPG if I didnt floor it everytime there is no traffic on the highway.

 

14mpg 100% city stop and go plus some spirited driving

 

i drive fast so avg is like 20

 

Agreed

Update with my first long road trip from New Jersey to Florida.

^^ Pretty decent mpg on regular gas. Is it an x or rwd?

Why are you feeding it with regular against the manual mandate? I have never tried regular, does your engine ping under full throttle at redline?

2013 g37s sedan, i'm getting around 14-16 on my first couple of tanks.

Did any of you notice improvement as the car breaks in, or should I expect this to continue?

 

I have an 09 G37X I'm getting about 22mpg all I do is hwy driving ... I just put a K&N intake on so not sure if it will get any better it's to soon ...

 

I dropped some unsprung weight (wheels/tires) and went from 17-18 combined city/hwy to 20-21. I do have a heavy foot, so that is a factor.

Road trip to Vegas when brand new I got almost 25 mpg... and I was doing 80+ the whole way.

 

my 2008 G35xS averaged 15.7 mpg for the 4 years I owned it. Best tank ever was seeing 360 miles, averaged about 20 mpg on that tank on the highway.

2013 G37 6mt is getting 17.2 mpg, did one tank to 375 miles, about 22 mpg.

Manual and 6th gear helps, as does lower weight.

 

I have a 2013 G37xS with about 1500 miles, and I'm getting about 18.8 mpg (this is what the status screen shows).

 

Your mileage seems 'normal'.
I have done quite a few manual calculations with my 2 G's and I found that the car computer calculates it about 1/2mpg (US) lower than what the manual calculation reveals. Not great news, but that's pretty close.

I got a 2009 XS a couple weeks ago and have been averaging 19.5
