Just completeted a 1 week-3250 mile road trip in my 06 GT. Averaged 24 mpg from Louisiana to Colorado and back. Going and coming doing 75-80 mph. Even took it up to the west portal of the Alpine tunnel of the abandoned Denver & South Park R.R. (10 miles of 10 ft. wide rocky road 4% grade ) top was just at timberline. Worst mpg was 23, best was 26.5. Car loaded down with tent, air matress, ice chest,etc. Plus me and the wife. Also made a side trip to the bottom of the Black Canyon of the Gunnison river which was a 3 mile long-16% grade. No problems the whole trip. |

I have recently conducted a experiment with my 05 v6 and only using a quarter of a tank of gas at a time if I drive at between 50-55 use the cruise and no a/c I can get 38-39mpg. All of my miles to work and back are 98% highway and 2% city and flat roads. half way there it's a 65 speed limit and the other half 55. so I kept it under 55 and its great. I couldn't believe it myself but it is true. Before I use to keep the tank full of gas and and drive 65-66ish with that its 29mpg.
I think also weight distribution has a lot to do too.
ya'll watch those twinkies now!  |

15.085 gals @ 362.9 miles was good for a 24.057 avg MPG in 60% city and 40% hwy driving.
It usually gets anywhere between 22 to 23+ MPG, but it broke the 24 MPG barrier for the first time. Not too bad for a manual V8. Woo hoo! |

I get 20 mpg in town and gas it every time I get a chance. On the highway I get 24 to 25 mpg. But I was getting like 17 mpg in town, and 20 on the highway before I installed my C&L intake and did the Brenspeed 93 octane tune. Not only did it transform the car into a monster, its much more fuel efficiant too. If you havent dont this yet you need to. |

I'm bettin' they would pull about 30MPG. |

I average 17-18 mpg in town. One time I tried really hard to get the best possible mpg in town and got 19 mpg.
On the highway I initially averaged 24 mpg, but after the addition of a K&N FIPK I jumped up to 26 mpg (both at 70 mph). That got me wondering what other mods I could do to bump up the power and mpg? Anybody noticed mpg gains with pullies or exhaust mods?
I received a Hooker Aerochamber Axle Back for Christmas so I'll keep track of any improved gas mileage. Of course I won't know for a few months until I grow bored of the sound it makes when mashing the gas!
I've also tried driving slower a few times and I gain ~ 1.5-2 mpg for every 5 mph I slow down on the highway. |

Stock V6 auto.
I have a 14 mile freeway loop that I can drive late at night using cruise control.
With a K&N drop-in filter...
At 60 MPH, I got 30.8 MPG, at 65, I got 29.2 MPG. The 65 one wasn't quite pure, I had to break a bit and then get back up to speed because of slow people on the ramps.
I did a run with the stock filter (14k miles old) @ 60 MPH right after that, and the MPG dropped to 30.5. I figure that's good for about $20 a year or more in gas.
Day to day driving I average 17-18 given the stop and go driving in So Cal. I'm a pretty mellow driver unless I have a reason not to be. |

Just got done doing some pretty decent mods to my '06 GT Auto last week(WMS CAI/SCT X CAL-2 with custom tunes from Brenspeed and 4.10 FRPP gears). Before the mods I was getting around 21-22 mpg running the 87 octane. Now after 2 tank fulls with the mods(93 octane tune as well) I'm getting right at 19 mpg. All my driving is a mix of 30 mile commute to and from work and city driving around home. After the gear install I try to keep my interstate speed to 70 tops(about 2600-2700 rpm in OD) to conserve some gas. I have yet to control the urges of getting on it pretty good from time to time now after the CAI/tune/gear mods, so I'm sure my mpg could pick up some...Oh well, it is to fun this way!!!!! |

I've read a few claims that just seem difficult to believe. I check my mileage each and every time I get gas. I monitor the mileage constantly with my on-board trip computer.
I get about 15 mpg in town and 24 to 27 on the road, depending on highway speed, temperature and traffic.
That's consistent with a 2005 stock V-6 and an automatic.
I can believe a V-8 with a manual would actually do a bit better. I once had a 2003 Mach 1 and it got better mileage than my daugther's 2002 V-6. Again, I checked it and checked it. |

The V-8 and V-6 are not that far apart in MPG. That's the essence of part of my statement. And with a manual, a V-8 can actually get better MPG than an automatic V-6. There may not be enough difference to brag about, but I believe experience will prove it will happen.
In town, I don't believe anyone, V-6 or V-8, is going to get better than 20 MPG. I believe actual figures will be close to 15 to 16.
I know that the cars can get 27 to 29 mpg on the road. It's 30 plus I have problems believing. |

Here is my log since new late last August. I don't do much hot rodding, but have yet to either run conservatively OR take it on a long highway trip for a full tank to see what my max is. Now with the CAI/Tuner/4.10 upgrade done I'm going on a semi long road trip next week.  |

I'm in the UK and pay over $7 a gallon for premium fuel so whatever you get, consider yourselves very lucky.
I've had up to 24 from my S/C GT and it's currently showing an average of 19.2. |
