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.
