I drove 170 miles west to Abilene to visit a few friends and to see my next base. She did well and I have about 850 miles on her now, I'm glad she's finally broken in. Now the fun can start.


Oh and I managed to get this on the way back.

 

How did you manage to get such good mileage? Were you going slow?

 

70MPH, 3:31's and one window down.

 

That's really good!

I hope my 08 GT gets as good when it comes in?

 

I just did ~3,800 mile roadtrip with my wife. We sat 88 hours in car (including all heavy city traffic in LA/ and SF). According to computer, my heavily modified stang burned around 210 gallons of fuel and MPG was around 22.

Everything worked great... I reloaded my tune after we came down from Lake Tahoe to Sacramento just to make sure, since I noticed to make 1½ psi more boost at Sea Level!!! We need to move Colorado by the Pacific and make nice big parking lot out of California!

 

The trip computers are never entirely accurate. Do it the old fashioned way and you'll find that the gas mileage isn't as high.

 

That may be true, but mine is pretty close. I've reset mine every time I fill up ( except once ), and it's always been within 0.4 mpg of my actual mpg as determined by miles/gallons used.

The one time I didn't reset it during a fill up, I reset at the beginning of a 150 mile highway drive, and my reading also said 30.0 after that drive -- 65-70 mph, 3.31 ratio.

 

Mine says 13.8 after 1/3 tank

 

Good mileage Corey!! Hey I did 3 years at Dyess AFB in the 80's. We had B52 D's (4 on nuclear alert) and KC 135's along with 3 squadrons of MAC C130's. Last I heard Dyess had B1 Bombers. I guess you will be Gasing up those bad boys!!

 

Yup, B1B's and C-130's (don't know what models)

 

I wish I could get that kind of mileage...I'm usually lucky to get 15 mpg.

 

I would take the MPG readings from the computer with a HUGE grain of salt. It's useful to figure out proper driving procedures, but it can be skewed to show very good results for instantaneous readings. I calculate gas mileage the old fashioned way, which takes into account a lot of the different variables experienced in normal driving.

 

Mine is always within .1 MPG of my mileage log. In Washington we fill our own tanks so I fill it the same every time. I was able to get 26 MPG on a 600 mile trip with a tail wind and using the cruise control.

Mine is always close and almost always reads worse gas mileage than I actually got by only about .1 MPG.
My best in a long cruise so far is 27MPG (and I only floored it to pass cars a couple of times).

 

The trip computer can take the overall average MPG reading as well, which is the same as doing the math the old fashioned way. I was referring to the folks who reset the trip computer and take the average/instantaneous MPG while cruising on the highway in order to get 30+ mpg readings.

The more city and stop/go driving you do, the lower the gas mileage.

 

I reseted the avg mpg when I filled up next to the freeway. I then got back on the freeway and headed home. So yeah, it was all highway on that reading.
