Thread: Whats your AVG MPG?

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.

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

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.
