just buy a v6 with a tune cai...its as fast as that 02 gt you have now....and drive it gently and you will see almost 30mpg on the highway. Not to mention, saving the 5-7k from not buying the gt. jmo..

My 08 GT has 3.31s... I drive relatively easy with usually only 1-3 full throttle launches per tank... mixed city/highway driving and I get 22mpg pretty much every tank... yesterday I filled up and drove 80 miles of highway at about 70mph the whole way and filled up again later that day and got 27.8mpg...

Yeah I have a 08 GT stick with 3.31 and I get about 20, 21. Mixture of city, highway. I don't see the point of looking for good gas mileage with a GT. How many v8's do you know get high 20's unless you are a grandma.

I don't get it...I drive mine somewhat fast but not too bad, and I cruise often and I only get TOPS 14 mpg...And the tank always says empty but I can only get like 13-14 gallons in the tank when I fill it up.

Wantsa Stang GT and wants better gas mileage... Sounds like a conflict of interest.

My Stang gets about 23 MPG, average, with about 95% highway and spirited driving. It gets about 3-4 MPG better than my SUV does so I'm happy. I suppose it's all a matter of perspective.

Yeah those on board computers are never accurate. Add to the fact that many people do not properly know how to calculate it by hand and it scews the numbers to look like they get better mpg than they really do. My '01 GT gets 15mpg around town and 19 hiway(heavily modded). My '08 V6 gets 23 mpg city and 29 hiway.

I typically get 25+ calculated mostly highway. If I do a lot of around town it will drop to the low 20's, stick w/ 3.31's. It all depends on your driving style. Also the computer always has me at .5-1 mpg higher.

I get on average 22mpg. That around 18-20 in city and around 25-27 on the freeway. I did notice a big improvement when I installed the K&N CAI and the sctx3 87 tune. I also have a 5 speed, 3.55 rear, end and Magnaflow axel backs.

It's amazing how much the mpg of these cars seems to vary. I get about 9-11 mpg in mostly city driving. On a roadtrip that was 350 miles all highway I got about 23 mpg.
