Maybe 30/70. I blast it around town, on ramps and down the highway, but cruise in gear, early shift and ride down gears all the way. It's the way I drive that gives me that kind of return. On one early tank I went 25 mpg because I was taking it easy. Watching your mpg meter and playing with your gear selection and not neutral coasting can give you better mileage.

TrueDelta conducts a real-world gas mileage survey that, unlike others, includes driving style and driving conditions. Results for the Z here:

Real-world Nissan 370Z / 350Z gas mileage

None for the 370Z yet--hopefully we'll start seeing some soon.

20.2 mpg around 330miles to the tank

50% highway, 50% city.

I believe I could do a little better, if i was not running late for work every day.

So high average speed on the highway?

well coming back home I ave. about 75-80mph, going to work late, about 90-100mph

I think the average speed is an important point. I checked my last full tank and the gauge showed an average speed of 42 with a mileage of 23.2. I did one highway run with an average speed of 67 and mileage of 25.9.

the mpg you guys are postin im def liking cuz i didnt think that they would be that high

Having a blast.
 

12.8 MPG last fill up. Having a blast.

21.6....and i get on it allot....nice

23 with an even mix of driving, 28-30 with mostly highway.

~11 almost all city and having fun.

22.8 over the past 6,000 miles. Mixed driving, playing occasionally.

I get 19.4 city and enjoy the hell out of it.

i have never gotten more than 19.0 mpg according to the dial. not a tenth more...

The best I ever got was17.4 under break-in by the book. Thank god I'm past this.
