Highway criusing 90% of the time and about 26ish mpg
I did find out that if you are driving and reset your info center when you have the average mpg displayed you can instantly find out your mpg at your current speed. I was going 35mph and did that and the comp was saying I would be getting 41.9 mpg! Woot! If only that was the speed limit around here and driving at granny speeds wasn't so annoying... |

17.8 that's a combination, 13 miles to work 3/4th back roads...never seen better than 22. That is with an Auto, stock gears. The trip computer is consistently .3 to .4 mpg worse than I actually get, weird because on my dodge its always 2.5 mpg better than the math... |

I get a very consistent 21.5-22.75 doing no driving other than my daily commute. That is some stoplight-to-stoplight (0-45MPH), some bumper-to-bumper (cannot get out of 1st & 2nd gear) and I get to hit 80+MPH every single day on part of the stretch so it is not all low speed.
That is calculated with math not the on board computer, take away about 1MPG if the air conditioner is running. |

I just got back from a trip from CT to FL about 2400 miles round trip with an avergae speed of 77 mph in my '07 GT/CS and Iwas getting 26.5 MPG. I did it as a straight one day ride about 17 hours each way and it was fun to take the cruise in the stang - would do it again! |

I just got my first Mustang, the 09 GT and I have an app on my iphone that calculates my MPG... so currently I'm getting 16 MPG and I'm driving a lot of highway this weekend, so we'll see if it changes much with that  |

4,602 miles from Kentucky to Las Vegas to Birmingham, Alabama and then back to Kentucky. I averaged 25.2 MPG until I hit Birmingham and did quite a bit more in city driving for the big Mustang show. MPG dropped to 24.7.
Normally in town, I live only a few miles from work, I get between 13 and 14 MPG. |

My MPG obviously REALLY depends on how I'm driving. If I'm "granny" driving, I get anywhere from 17-20mpg IN town... On the highway, I just took a 120mi 1way trip and set the cruise at about 71, got 30.6MPG. This was a little more than usual, normally it would be around 28.5 at that. If I am in town and accelerating hard, or racing at all, then it's more like 12-14mpg. Also, a lot of mods help with gas mileage, and I have most of those mods. (tuner, intake, and pulleys)

LOL

Have about 6000 miles on it now, 4000 of it on the highway. I only use the on board computer to keep track. To lazy to sit at the pump with a calculator most of the time.
In town (no traffic jams) 16.5 to 18
Mixed 18 to 21
Highway (no stops between gas stations)
27.5 to 28 at 75 - 80 Mph. -1 if the AC is running.
Best ever was 32 at high altitude and 50 ish MPH.
Worst 23 at 75 MPH but there was a big head wind. |

WOOOT! I just went on a 600 mile road trip & have good news.
24mpg freeway!
18mpg city.
That's driving, "regular".
If I drive aggressively (having too much fun haha  ) I'll get from 15.5 to 16.5 mpg city.
08 automatic GT with K&N air filter and thats it.

My daily average is around 28.5, which includes 15 minutes of city driving, 60 minutes of highway driving and 15 minutes of seriously mountainous backroads.
The best I ever got was 30.1 on a 60 mile stretch at a blistering 55-60mph.
I will never do that again, just too damn painful...
Oh, and the V6 can run at 100 at a consistant 19.1 mpg
Or so I heard... |

My daily ~40 mile commute consists of about 30% light-to-light at about 45 MPH in between, then 40% of bumper-to-bumper "highway" driving from 20-60MPH, then about 30% of clear toll-road driving at 70-85MPH. For four years my mileage was a consistent 21-22 MPG in the 6 months of fall-winter-springtime, then about 20-21 MPG in the 6 months of summer (I live in Texas) due to the AC being on.
I recently replaced the factory unit with a C&L racer CAI, then de-tuned it (timing) to run on 87 Octane and so far (summer only at this time) I am getting a solid 23-23.5 MPG with several tanks, my driving habits have not changed so I'm crediting the CAI for the gain. |

2008 Convertible V6 automatic.
overdrive on and TCS on = 200-240 miles to a full tank.
overdrive off TCS off city driving = 140-150 miles to a full tank.
I have a bit of a lead foot. |

I'm now at 16,000 miles. I reset the message center. On a flat stretch from Petaluma to the bottom of the Waldo, my high is 24.3 going about 65. Thats on an 87 performance tune from Bama. |

| | | 4.0 V6 Mileage
I just bought my Stang when I took it on the 45th Anniversary Drive for Mustangs Across America. The most impressive freeway mileage I got was drving out to Las Vegas on Friday night. Lots of crazy drivers, too crowded for cruise control, yet I averaged 29.3 mpg from Barstow to Vegas while hitting speeds up to 95 mph. On the wide open runs across Arizona and New Mexico I was getting 27-29 mpg, and it didn't seem to matter if I was averaging 80-85 mph for long stretches (trying to keep up with all the Shelby and Roush cars). The car was stock at the time (except for my sequential tail lights!)
Now I get 17-18 around town, and it looks like I get about 30 in pure freeway drving (based on a medium length drive last weekend). Pure highway mileage is great at any speed, but any stop and go driving really brings down the average. | | Thread Tools | | | | Display Modes | Rate This Thread |  Linear Mode | |
