Thats about what I get, 14-15

I average 21-22, but my drive to work every 3rd day is about 25 miles with only a few lights.

As BillyBobJoe said, if you reset all of the variables and do the math after every fill up, it's within a few tenths. I'm getting 20-22 with a manual, no mods and mixed driving.

i get 9.4mpg here in brooklyn dont go on the highway that much.

18.5 with half town and half highway driving. Seems to be pretty accurate too. Those who average 11 or 12 need to keep the right foot under control if they want better mileage. If not, b*lls to the wall and pay the pump.

I normally keep the cruise control set right at 100 and get 19.something to 20 mpg. I have a 60 mile trip to work everyday with no hills.

Imagine what kind of mileage you'd get if you set it at the speed limit![:-]

I've found the trip computer is accurate to about .1 or .2 MPG after I do the math.

graystanggt

my 07 gt gets 18.5 to 19 driving in the city. I cant imagine only getting 11 or 12 mpg's.

slySTANGguy

mine is not accurate at all, i averaged about 22-23 on highway with CAI and 93 tune

Even with the computer, I still calculate my mpg at every fill-up (it's a 32+ year old habit, i guess). I typically drive my Stang about 90% highway and the computer says I'm getting ~24. My calcs say 22-23. I trust my calcs over the Stang's computer.
