I am curious to see what you guys/gals are getting as average mpg. Let us know a little about the car and the type of driving your doing. With gas prices over $3 a gallon for regular gas mileage is a major consideration when buying a car these days.

Stock I got about 20.5 MPG avg (70% hwy 30%hwy) at 309 RWHP

Went with TR224 cam and a poor tune and got 18.5 MPG avg at 375 RWHP

Since I've worked on the tune for dozens of hours and got it back to about 20 MPG still putting down 375

I went from 25mpg on the HWY to 18-20mpg on HWY with mods listed below.

I average 15-17 with mixed driving per tank. I did not buy this car to get great gas milage. Heck it still gets better than my F-150.

I get 25mpg mixed, about 60% highway. I'm still playing with the new cam but it was getting better before parking it for the winter. Should get a little better in the warmer weather.

10-12 in town. 16-19 highway. 16 mixed.

If mileage is a major concern for you, stick with your Honda.

Oh...with cam, I still get 23 out on the road, and don't do enough city driving to be able to tell you for sure, but my guess would be 16.

I am just curious about real world mileage as opposed to the epa estimated ratings you see and hear. Im currently daily driving my 97 sonoma 5 speed 4.3 zq8 and am getting an average of 21-22 mpg, so it looks like a GTO wouldnt be too much of a change for me with mostly highway mileage.

And next time, maybe suggets buying a Cobalt, a Focus, etc if your interested in seeing the American auto makers still in buisness in 10 years.

how are you guys gettin over 20mpg? i drive mine pretty decently(obviously there are times i don't care and i drive it hard), but i seem to be down by the 16mpg range unless its all highway driving like my cross-country trip, and then i only got 21.something...everything on mine is stock

Are you calculating the mileage on each tank or are you just going by the little mileage readout on the dash?

ygbg_04

is the dash thing not accurate? cuz ill add that to my list of why i wish i had a different goat

On most vehicles they arent that trustworthy. Plus, a lot of times they are a "lifetime average" reading, not an average per tank. do the math after filling up one time and see what it says compaired to your "mileage gauge"

I reset my gauge with each fill up. It was typically 2mpg high when I actually calculated it. After I put full boltons it was reading 25.5mpg, yeah right try 18mpg. The readings were rediculously high because I have bigger injectors. Needless to say I dont even look at it anymore.

Says the guy with two Hondas in his sig And in case you haven't heard, the GTO WAS BUILT IN AUSTRALIA, so save America and buy a Ford.

Curiosity is also much different than "major concern". If mileage is a major concern, don't buy a GTO.

Can't tell you for sure on the 04, but on the 06 the factory tune is pig rich up top when in PE mode. I didn't have HP Tuners when I was bone stock, but just getting a tune and dialing in the VE and MAF tables will give you better mileage. When I'm talking 23, I mean we're talking setting the cruise on 80 and leaving it there...plus driving for mileage.

I reset my computer each time I fill up, and have found that every time I do something that would change the mileage, the computer is off for a "while", then comes back to true...and I've verified mine with actual calculations, not just the computer.

we have the reset button on our gto's but i think i will still be checking it manually from now on, thanks guys

I check mine by hand every once in awhile to see what the difference is. From day one, its been about .5mpg high. That has been through 4 cams and various mods. Has stayed pretty consistent, so I go off that. But I do continue to check it every now and again just to make sure.

HQuakers

about 18 for me, but I just did a 1000 mile round-trip weekend and got 24 while cruising at 90mph in 6th gear almost the whole way.
