Lie O Meter
With 7800 mi on the clock,my Lie O Meter has settled down at 13MPG unloaded City driving for the last 1000mi. When I first got the truck I frequently reset the milage and got very encouraging numbers like 19-20MPG. I think that is why some posters are claiming fantastic milage that sounds too good to be true. Ya need to leave the reset button alone even if you don't like the numbers it is giving you. My hand calculated MPG is pretty close to what the computer is saying now.

My lie-o-meter doesn't do anything.
My lie-o-meter has stayed at 11.8 to 11.9 MPG since I bought the truck but, my economy (hand calculated) has ranged from 9mpg (first week or so I had it) to 15ish (last fill up) though, the lie-o-meter hasn't moved up or down to indicate the difference in MPG (these numbers are all city mpg...I rarely get on the highway).
I have a little over 4500 miles on the truck and have never reset the lie-o-meter, just the quick trip a/b miles every fill up and the engine hours get reset every oil change (so far one time).

Since it's an average, after the reset, it should take a few tanks before it displays the correct MPG right?

I've been resetting mine after each fill up. It will give you some good numbers for the first 100 miles or so, but it does take a while to settle down to very close. Also, if you'll read your manual, (I don't have it in front of me right now), but it says to check your highway mileage... set your cruise control, wait for about 5 minutes or so, then reset the MPG and it will give you your highway average. Something like that.
