My avg MPG on a 2000 mi road trip surprising
I found that the car gas meter is actually very accurate, which I wasn't expecting. I calculated gas mileage by dividing gas put in by miles driven. I drove easy using cruise control 90% of the time at 70-75mph and pounded first through third about twice each way. Car is a 13' GT speed all stock.
* NJ to FL the car did 26mpg (actual) while the cars computer showed 25.9. With total of three occupants including myself.
*On the way back from FL I rode loaded with a total of 4 occupants including myself and a trunkful of luggage. The car did 26.5 mpg.
*Total round trip cost me right around 280.00. I've done this trip many times before and in 2011 I paid approximately 240.00 round trip in a 2010 4 cylinder Honda Accord! It's worth the extra 40.00 :-D
Comfort is another story. I was fine, but my passengers had some complaints haha

Highway cruising can be provide some amazing fuel mileage for a performance engine. What gears are you running?
My GT has seen quite a few 1000+ one-way miles trips in addition to countless 900 mile round trips, so I have tons of data (I've been hand calculating fuel mileage since 1977). With my set-up in my GT, anything over 70 MPH will average increasingly less fuel mileage. But at a steady 55-65 MPH (yes, there have been a number of times I went fill-up to fill-up at about 60, and NOT by choice), I have hand calculated 27-28 MPG on the 4.6L. Make that 80-90 MPH pump-to-pump and I average about 18-19 MPG.

I just did a 3,000 mile trip from South Carolina up to Upper Michigan, down through Wisconsin, and back to South Carolina. Most of the freeway time was a minimum of 75-80 mph, quite a few times over 80, with a couple quick runs over 100. I also may have left a couple black marks in front of my in-laws when we were having a family reunion (common occurrence with the yoopers I know).
I averaged (according to the in-dash measurement) 22 mpg for the entire trip meter. I used the second trip meter to measure each tank, and they ranged from around 17 mpg up to almost 25 mpg. I hand calculated several tanks to see how accurate and it was always within about .3 mpg of the in-dash calculation.
My car is a '13 gt, 6 speed manual, with 3.73's running premium the whole trip. Just the wife and I with a full trunk and backseat.
