Whats your AVG MPG?

14-17 city
18-20 hwy

I think the DIC is most accurate as it gets the info from exaclty how fuel is injected, but is only the average. I dont think using the fuel pumps is more accurate than the DIC. Someone needs to do this, any "MYTHBUSTERS" out there. On the highway I will keep hitting reset and it will show instant MPG's, I can show 30-35 at around 50mpg as long as there is no wind or hills. I avereage about 22 in the city, and 28 on the highway, pretty good even by todays standard with v6's. Gosh, I saw a new g-8 I think at the flee market and the window sticker said 15 city and 15 highway, 6.0l, 355hp.

Same Here but since i put the Green Bastard Performance Ported SC and TB on my MPG's have went up. :th_laugh-lol3: Now i just need to get a tune. :th_thumbsup-wink:

IDK if the gas used reading is correct at all. Ive cleared it and ran out of gas twice & both times it said 15 gallons used. But the manual & zillions of ppl insist the GP's have 18 gallon tanks. Maybe mines off idk.

on both my 16hr trips to indiana from florida, driving straight, 75-80mph i saw a consistent 31 mpg on the highway.

i have probably the worst gas mileage ever. I get like 15.3 in the city, but i have only had the car like 2 months and on saturday im changing SP wires and plugs, changing air filter for the time being until i buy a fendwerwell from TDC racing. Anybody else know anything else i can do to make it any better?

City : 18ish mpg
Hwy : 27-30 mpg
Park : 0 mpg (sorry late night humor)

15 but I'm probably in bad need of a tune-up.

19.1

all day.

I get
16mgph in the gtp
6.4mpg in my trailblazer

Whoah ditch that gas guzzler & get your GTP tuned up!

0-mpg!!! Haha @ least until I put a new motor in.

23-29 stock depending on if i am in stop and go traffic or not...usually its 26

i average 18.2 with city & highway mix!

I commute and am able to pull between 28 - 32 mpg.
Try to hyper-mile it.
