I Have A 04.5 6 Speed 2500 Regular Cab 4wd It Is All Stock Except Exhaust And I Seem To Be Able To Get The Moniter To Stay Around 28 To 29 Miles Per Gallon If I Drive Easy And Under 55 Does Any One Else See This Or Is My Moniter Way Off? Today I Drove 75 Miles To School And Back And My Fuel Gauge Hardly Moved... I Havent Checked It Any Other Way Other Than The Moniter But I Hardly Use Any Fuel And Just Wanted To See What Everyone Thought Thanks

i have an 04.5 the overhead NEVER goes above 23mpg.
did calculate by hand and its off by .5 - 1 mpg usually.
sometimes it reads 2 mpg off , not sure why the flux.
could be a thousand things.

i DO reset it everytime i fill up.

oh and dont trust the distance to empty either. when i had my 03 i was watching that and not the fuel gauge, well lets just say i had to walk about 5 miles with 2 five gallon gas cans that i had to buy. i was not a very happy camper that day.

Since you're going to school; if you don't know how to compute actual mileage, ask your math/algebra/calculus teacher!!!!:rof You will truly be "enlightened" then!!!

My OH averages about 7% off.

On my dads 06 even if he resets it at every fill up it only uses a pre programed amount of miles, not since last reset. He can have 1000 miles since last reset and have towed for the last 1000 then drive 20 miles w/out a trailer and it will jump up 2mpg's, thats not real possible if its averaging since reset.

Anyone know how many miles it really uses?

My miles to empty is pretty good. I filled up once with 2 miles to go and put 33.7 in. Its supposed to read 0 to go with about 1 gal, IIRC. My light comes on with about 3 gals left.
