Only got about 475 miles on mine, mostly city traffic (we don't have freeways where I live)... with a little of deliverin pizzas. I'm currently getting 16.2 mpg, which I don't consider all that bad really. I'm fairly "gentle" most of the time, except when I'm not.

It seems like EVERYONE is doing better than me. I have '06 Gt Vert and it gets 13.5 MPG. I don't know if it because I only had it for 4 days and put only 150 miles on it. Does anyone else have any explainations??

Haha, I don't stomp as much on it as one might think. I really drive "regula". I usually go to about 3000rpm's in first gear and then around 2200-2500 for all the other gears. And I usually give it a good enough throttle but not "stomping" on it like I want to....trust me I can't wait til I break it in.......

Speaking of which, does anyone know a good break in period timeframe?? My dealer said there are none since now-a-days these engines are made with such tight tolerances but still I like to believe there is a Break In Period. I think I will drive like I am now until I reach 1000miles or so.

So I would.......
-Keep it under 3000 rpm's
-Keep it under 70mph
-Don't use cruise control

Does anyone else have any other suggestions

GT, manual, no mods running 87 octane ... I usually get 16 around town and the best I've ever gotten was 26 doing 72mph in cruise control on the hiway. I could prolly get 19 around town if I didn't drive like I do and at other times, i'm down as low as 12.

Man, the sound of some of these numbers is making me feel better about mine, 18 city 26 highway. One of the other forums had people claiming 8 gajillion mpg with flooring it on city driving. The green beauty and I were feeling inadequate....

Wow I see some people with some horrible gas mileage!! I feel a lot better now!!! 92oct, 447rwhp, average 20mpg and I race everything!!!

With regular (87 okt) fuel I get 24-25mpg on highway, 20 mpg mixed and 15-16mpg when I'm on the mr. Leadfoot mood.. :tongue About 2-3mpg difference to my economustang which I fill with 91 okt (lowest rating found in Europe..)

Isn't the GT's supposed to run on 87 octane?? I thought all the testings done to it was solely based on using 87 octane? I thought optimal results were done using 87 octane on the stock engine.

I figured since all the results are based on 87 octane and I haven't tuned computer to run on higher octane, it would be a waste of money going higher in grade.....well, unless I do a MFI or something like that that NEEDS to be tuned.

Does anyone know of the cons of using higher octane grade for no reason? Besides the extra cost.....
