Actual Mpg

Fatpolish · Feb 25, 2015

Current owners can you please share the actual MPG you are getting, what rear end you have, and driving conditions. About to pull the trigger on a GT and just doing my research. Thank you all in advance!

RDMYPNY · Feb 26, 2015

20 Mpg and I accelerate hard on most green lights and freeway on ramps. I'm taking it on a 400 mile trip tomorrow and will try to drive it gently.

I have the 3.73 rear end.

Fatpolish · Feb 26, 2015

Do you have the at or mt? That doesn't sound too bad. I commute 135 miles round trip and just wanting to get an idea of my fuel cost per month. Thank you for your reply!

RDMYPNY · Feb 26, 2015

MT. I have 5k miles on mine so far, just installed flow masters so we'll see how that effects it. I got 25.8 MPG when it was new on a road trip that had several 5000+ mountains.

My GT has right at 500 miles on the odometer and I'm seeing 15mpg (mixed driving in the hills). It's a 6-speed manual with the performance package, so 3.73 gears.

84Ttop · Feb 26, 2015

15' Automatic with 3:55 gears.

310 Round trip 100% highway i averaged 30.4 mph
Driving around town I average 22 mpg if I drive sensibly and as low as 18 if I'm really getting in to it.

FWIW, car as just over 1k miles on it (1047 to be exact) and has a Vortech JT trim supercharger setup and Magnaflow cat back. The car is also custom tuned which can account for some of the gains here as well.

15 mpg
6-spd
3.73's
stop and go traffic half the time, slow moving traffic the other half.
Level of hot rodding: Sometimes.

Now under traveling circumstances, like a weekend trip half hour away, around 20 mpg.

No interstate trips yet so I can't give an accurate highway mileage.

If those miles are pretty much all highway miles, then you should have no problem hitting 25 mpg with an at/mt on 3.15/3.31 gears. My '13 GT mt\3.31 gears got 25 doing a 40 mile round trip to work, and i don't baby the car.

My '15 isn't broke in yet as i'm running it in higher gears and still getting 22-23, which is even better than when i broke in my '13, so i'm hoping for 25 or more out of this once i break 1k miles.

Thank you all very much!

Been meaning to update this response for a couple weeks now. After putting a few thousand miles on the car, both car and driver have settled down into 16.8-16.9 average mpg.

2300miles on my GT w/PP 3.73rear and I'm getting 20mpg. 60%highway 40 city. I could probably get more if I was easy on the throttle. The 3.73 kills mpg but you don't buy a GT for fuel efficiency.

n8rfastback · Jun 10, 2015

4000 miles on my GT PP. my drive is 20 miles of highway and 5 miles of stop and go. I'm averaging right around 21 or so. I get 25 on the highway, but the city portion of my drive brings the average down quite a bit. I have yet to average under 20.

NJBob · Jun 12, 2015

I'm getting 19 to 22mpg on a 14 mile trip back and forth from work (Manual) speeds between 70 and 120mph hard acceleration getting on hwy. 12MPG hot rodding around.
26+MPG steady on highway at 70 to 80. With a Tune.

echo7 · Jun 13, 2015

Hate to show off my epic highway mileage, but I have too! 5.0 V8, Auto, 3.15 gears.

This first pic is about 300+ miles, non stop, doing 75-78 mph on the interstate in Florida and Georgia.

This second pic is an average of my daily driving to work, over 2000 miles worth.

What are you ecoboost owners getting?

Frustrated that they didn't opt for the V8 would be my guess.

Stan McKinney · Jun 15, 2015

Not nice. I have one and love it. Plenty of power and 32 plus miles per gallon on the road. I have had GTs in the past with less horse power. Can't Mustang lovers get along?

Canadians... I'll tell ya

Just kidding @Gearbanger 101

dhcolesj · Jun 27, 2015

I'm getting around 21 - 25 mpg (depending on if I have to race a Camero or something). But, if I drive with the cruise on I can get right at 24 pretty steady. 5.0 Manual Tranny, 3.73 rear.
I have a 50 mile ride to work, so I can usually get a pretty good gauge.
If there's moderate traffic and I have to slow down, I get higher mileage for some reason.

Stan McKinney · Jun 27, 2015

My ecoboost automatic which I still love and has less than 2000 miles, gets 32 on highway easily and low 20s in town. That is with a heavy foot.

They make new pistons every day, so why worry?
