Doing this same exact method I get identical numbers that you are getting. If I granny it I get maybe an extra 40 miles to the tank? I fill up when there is 1/3 tank so at best I'm getting 240 miles to every fill. I know I've gone as low as 160miles on 2/3 tank. And to be honest, I haven't driven anywhere near as hard as I drove my 09. My 09 gave me 300 miles on 2/3 of a tank consistantly. And I beat that b1tches gas pedal up. I'm disappointed with my 11 mileage.

On roadtrips, the Z is actually really good with fuel consumption. I have a few trips from Fort Hood, TX to Fort Gordon, GA and one from Fort Hood, TX to Baltimore, MD (and back of course). I didn't let the fuel go below 1/4 tank, but I was always above 330 miles at the time.

Local commutes are a whole different animal though. If I got 300 miles out of a full tank (no dots left) I was happy.

fuel consumption is not a priority for me. If it was, i would have bought a different car :)

agree with buddy up there, however i got out of a full tank 35miles.
i drive mostly highway, i still breaking her in i have less than 1000 miles and i be making from 0-60mph using all 6 gears. sometimes i catch myself doing 40-50mph on 5-6th gear.

I got about 500 miles on full tank

with a name like mandingo, all we can expect is "go big" :icon18: yea im glad nissan didnt over-hype the mpg thing. a nice little suprise after buying a car, even if we never make use of it (mandingo):rofl2:

I'm somewhere between 25-27.5mpg generally. I drive 5mph over the speed limit. Beat all the traffic to wherever I'm going. However, rarely do I bury the thottle.

The best mileage out of a tank of gas I've gotten is freeway with hills/turns at 28.5mpg. The worst mpg is when she is driven like she was meant to be driven about 21mpg. I'm very happy.

I'm still in break in as far as I'm concerned with only 4500 mile on my car. Tomorrow is a oil change so maybe my mileage will go up. I guess I should take a long drive down HWY 5 to see what my best mpg can be.

Believe it or not this about the same mileage I get in my LS1 cars. About the same HP but, they have 2 more cylinders.

I should also add that I have never driven my Z with the SRM off and I'm sure that kills mpg some also, but it's so awesome.......

thanks for your posts everyone. seems like this machine is capable of incredible mpg considering its power. depending on driving habits of course

I usually get around 22mpg. About 380-390 per tank before I fill up.

I'm at 19.0mpg and I drive like a grandma, never rev over ~4k. Most of my miles are around town though, stoplight to stoplight, so maybe my 19 would be a little higher if I got on the highway more often.

Im close to if not past red lining at least once every drive. I drive hard and on hills and low mountains and my mpg is still around 22-25. I good alignment man does wonders for you

:iagree: yessir
