My lie-o-meter was feeling extra generous this morning.
It went up to 32.3mpg before starting to come down. 100 miles later its around 26. By the end of the tank it will be sitting at 22-23mpg. It was entertaining to watch.

The gas station I typically fill up at is about 2 miles from my house. I always reset the MPG gauge when I fill up and try to see how high I can get it on the way home. If I coast the last 1/2 mile all the way to my garage door I can get into the upper 30's pretty easily.
Honestly, I can't call mine a lie-o-meter anymore. Since I re-calibrated my speedo to match my actual speed the mpg readout is always within 0.1 mpg of what I calculate after every tank.

I reset the trip meter once right before a 30+ mile drive down a mountain. I got 36 mpg over that stretch. I've gotten single digit readings over some stretches of road too.
But driven enough miles things even out and I've found mine to be quite accurate. I used to hand calculate every tank just to verify what the gauges were telling me. But after a year and 21,000 miles I've stopped. So far the most it has been off was 1/2 mpg and the truck was showing 1/2 mpg worse than I got hand calculating it. It is usually around .2-.3 mpg off and high about as often as low.
Our Honda however is always optimistic and by a significant amount. The last tank I hand calculated was 28 mpg, while the gauges showed 32 mpg.

To think I get real proud when mine shows 18 MPG going down a hill for long periods of time, although it did show 25 once. I do get 32-34 out of my Mustang though.

After fueling up then resetting the lie-o-meter i've gotten up to 28mpg (combined hi way and city) but leave the reset alone for a while and it'll get a more realistic mpg until the next fill up.

In the almost 3 years since I posted that I've learned quite a bit more about my truck. I calculate after each tank of roughly 33 gallons, and my meter is consistently 3% optimistic.
