7AT w/41k on it
~23 combined
19 city
28+ highway going about 80.

I've taken it easy now. The real-time MPG meter helped in determining how much throttle leads to what MPG. Also, I trust my MPG calculator. I check mileage when I fill up and the computer is spot on.

That is a nice little app. I have been using an app called MPG from back in the days of the Newton Messagepad (yes, some of you may need to look that one up, it was the first real PDA :P). MPG does maintenance and other things as well, so I would suggest checking that app as well.

My phone is almost always with me, so its easy to record. I have history on all my cars going back 10+ years. So far, I only have 3K on our 2010 ZR 6M that we picked up in may with 2500 miles on the clock.

20.9 Average (23/18 max/min split)

Never have done a full tank on the HWY, but cruise with top down nets 25+. Top down motoring plus A/C will kill 1-2 MPG from drag but its worth it.

I get about 23-25 mpg. I do alot of interstate driving with my top down. I think the gas milage is very good. Happy motoring :driving:

Not sure what a city only cycle would be, never done one! We did 3 long road trips and the computer said 27-28mpg average for highway.

I never keep track of the gas mileage on my "Z." I bought it for a sporty and fun car to drive. When ever it needs gas, I fill her up. I would notice if it was using excessive amounts of gas, but so far it seems normal for the way I drive.

Just took a trip from Austin to Dallas and tried to see the best mileage I could get. I was focusing the whole time on going really light on the gas and ended up with an average 31mpg at around 70mph for the 100% highway portion of the trip.
For normal Day to day driving I usually get 18-21mpg though.

Stock base model 6MT

I got longtube headers coming soon and eventually some intakes, really curious to see how those affect my mileage.

can you ever reset these? or how do they work? l

Hold down the left button for a couple seconds while you are viewing the mpg screen. Just like a trip odometer.

I know this thread has been open for a while but just wanted to add my two cents. My mpg is 21.2 at 33 mph. I don't pay attention to the rpms when I shift, I pay attention to have fast I'm going. I shift from 1st to 2nd at 8mph, 2nd to 3rd at 16mph, 3rd to 4th at 25 mph, 4th to 5th at 28mph and 5th to 6th at 33mph. If I am ever going above 33 I'm always in 6th. Now that is about what I shift at. It works very well though. If you read your owners manual it gives you this very same info on page 5-19. It is the suggested up-shift sped for best fuel economy. And I do a lot of city driving with stop and go as I live in San Diego. Also my mpg used to be better but since I got my berk hfc and my berk exhaust my mpg has gone down to 21 as I love the sound my exhaust makes so I tend to really get on the gas more now then I did before. I hope this helps you out :)

I'm thinking you didn't need a Z unless you go to the track every weekend - a Miata would be just as fast with those shift points!

I get around 17 MPG with the 7AT when I shift manually (I'm only in 7 on the highway and rarely in 6) but it is better in A mode.

OTOH, my normal drive is a ten mile commute with a 65 highway section for a mile and mostly 35 MPH city the rest of the way, with a few trips to lunch at 40 - 50 MPH during the week.

You actually have it backwards, if you like short shifting you want a Z or higher. You know the Z has decent displacement. Lower shift points when not using the happy pedal make sense. No different then the 1-4 skip shift on the small block chevy: you can save fuel and you don't need to unleash the hounds between every light (though it is fun).

In a smaller displacement car, assuming similar gearing, you won't be able to short shift nearly as much, and 6th gear < 40 MPH will lug a Miata, but not a Z.

Both cars enjoy a good flogging : they are sports cars for a reason, and respond accordingly. You don't need either, you just want and enjoy them :D

My latest trip to Reno, NV and back I achieved 29.8mpg in my '03 Special Anniversary Vette. That was better than my 350Z which I took the same trip in 3 years ago. The 350Z got 28.5mpg. It would get 28-30mpg consistantly on long cruises IF I could keep my foot out of the thottle.

I'm still in break in on my 370Z and it's nice to know that I should expect an increase because I'm only getting around 24.5 city/freeway right now. Although that is acceptable for the performance bump from my 350Z to the 370Z. I'm expecting 30mpg plus.

However, I squeeze the thottle during the work week and save the performance driving for the weekend.

In my 2010 Prius I was getting 50.5mpg... I just couldn't handle driving a tin can for the next ???? years. I'd rather pay $100 more a month in gas than to drive that Prius day in day out. Maybe someday they'll make a Z car that performs and gets that type of mileage.... I'm down for that day and will trade my 370Z in on a second year model. ;-)

95% city driving nets me 17mpg

Now that's what I'm looking for... :bowrofl:

During my brake in I received 18.9 as an overall average. I'm hoping for qa minimum of 20mpg's. That would be good performance for this amount of power. On my 09 I was getting 19.0.
