In town 19 to 22 mpg depending on traffic. 40,000 miles on the vehicle. Six speed models have a 3.69 ratio rear end IMO the gas mileage is pretty good considering 332 hp.

That's more like it.
If guys are realistically pulling around 26 mpg or thereabouts on US gallons, it puts Nissan's numbers about right at 32, 33-ish for an Imperial gallon. That was a number I figured I was able to live with before I bought my 370.
Now I just have to do all my driving in the U.S.

104

i average about 22mpg in my daily driving. havent went on a long trip to get a hwy mpg reading yet. i'm skeptical about the 30+mpg claims... it's a 370z not a prius.

Apparently there are a lot of people who get in the 370Z and dream that ey are in the Prius, drive in the slow lanes behind big SUV's and boast of their mileage.

Really impressive how these things can do 30+ on the highway. I haven't seen better then 28 on mine, however. For the guys getting 30+, are you hypermiling?

How off was the computer from your calculated? I've seen 28mpg on my computer didn't realize that would be off.

I routinely get 28-29 mpg cruising at 80 mph on cruise control (actual calculated mpg). I imagine 30+ would not be difficult if I drove 65-70 and didn't accelerate to close gaps. Definitely not hypermiling - if you are, you should be driving a different car.

So it appears EVERYONE is getting better than my 17 MPG on the highway.

My car just went in for the first service so all the tires have the right amount of nitrogen.

Not sure why I am not seeing good mileage like the rest of you. Any one have any ideas??

I don't understand how you're all seeing such good numbers. I average 18 on my daily commute, and get no more than 22, 23 on highway. And it's not like I'm always driving like I stole it

You're only going to see the 26+ on those long open highway cruises

What are your mods and how many miles?

Typical culprits are high-ish fuel trims (any CEL's?) due to either MAF or O2 misreads, which can be caused by air turbulence from vibrations or bends in the intake set-up, flagging or dirty sensors, vacuum (and exhaust) leaks, failing cats, etc.

FWIW, mostly city driving, tuned and LTH putting down around 310-315 whp, and I see a very consistent range of 19.2 to 19.5. I creep up on 20 - 21 or so with mixed highway driving, but lately I'm 95% stop-and-go.

However, I was briefly dropping to a pitiful 16-17 mph, and it turned out to be a bad heater circuit on the primary O2 causing it to not get up to proper warm-up temp.

my G only does about 15mpg on congested surface road commute so that's not too far off.
