if you have a O/R pipe that is one of your problems. There are ppl getting over 30 in their GT's but they're doing 60mph on the interstate, Might be hard to believe but I believe it.

 

Well, I put on the CAI and registered 31 mpg making a 40 mile trip each way, the car is a lot more responsive to the throttle and it feels like it picked up a few more horses.

I am really happy with it now, that trip was mostly all hill's and curves, anybody says a CAI won't do any good is nuts.
It ain't my imagination either.

 

or has leaking spark plugs........

 

I pull inflated mileage numbers out of my imagination.

 

i have a 08 v6 mustang, and im getting about 15... i mostly drive city too

 

stop riding on people ***'s and you might get better gas mileage.

 

dude that chin spoiler looks pretty dam gay. it is like your driving Jay Leno's face around. AHHH Puke!

 

Hey, noob. Shut your face.

EDIT: I forgot my smiley...

 

Im 15, i only have my permit. But i average about 22mpg in my 97 GT. I do a highway city mix. I do drive with a slight case of lead foot.

but remember...were all driving mustangs here, not civics lol.

also btw. I WISH i had a chin spoiler.
