What kind of fuel mileage are you stock, or lightly modded late model 4.6's? I have a friend looking into buying one, but the projected 17 mpg is a turnoff... Is this close or what?
From the showroom in Baltimore to my house in NC I got 29 MPG.
With the Mods below, I can pull 22 MPG all day long around town and dip to about 20-21 if I do a little "spirited" driving.
On the Hwy, I pull around 25-26 MPG
24.4 MPG with the mods listed in the sig. That was 100% highway at 80 mph. The only time I pushed the brake or gas was when I went on the acceleration ramp and when I exited to go to the gas station.
18 in the city, 26 on the highway and that is with a little bit of spirited driving here and there. Car is completely stock except for the K&N and a Magnapack catback is going on tomorow.
I get average 21-24mpg, on the highway, I got 30mpg and that was highway only at 110km/h, I get around 450-500km/tank in mixed driving, but when I step on it then its a little different, I got 350 once with it, but at the time I was only using it during the weekends so I was driving it pretty hard.
i'm pretty much stock and i don't drive it to save mileage . I get about 260 miles on about 13 gallons (~20-21mpg). my bf (stanglou) gets the same and he has pretty much every bolt-on and full exhaust. we both drive some highway and city. just hwy it's close to 23-25mpg.
On holidays this past summer, my G/F and I followed her parents out west, every time we stopped for gas, my Stang was 2-3 bucks cheaper to fill than her mom&dad's Concorde It made her dad cranky. On the way home I was driving 80mph and they followed behind us and when we stopped for fuel, my G/F's dad said he'd fill my tank and I was to fill his, b/c he said I must be cheating and not filling mine all the way up. This time the Stang was just under $8 bucks cheaper.
Around town I'm sure his would be better, but on the highway the Stangs are pretty good.
Edit: I live in Canada and gas is about $4.00 a gallon, so it seems like more of a mileage difference than there really was.
I average about 17-18 mpg in town, but that's with some "fun" driving thrown in. If i could stay out of it for a whole tank i'm sure it'd do better. With about 50/50 town-interstate ratio i got about 19-20 mpg.
