mine is almost always off by a half gallon or more....nd yea the mpg the car says ur getting is usually a little off but...for me n e ways...it is only like a few points off from what my calculated is

even on the parkway i never seen it past 19.3

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.

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?

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