My last two tanks have averaged over 24 mpg, and this is mixed driving. The tank before these, I got 22.34 mpg, but I had a small trailer for 70 of those miles along with 2.5 miles of pulling a parade float for Veteran's day.

My mileage has gone up since summer, as I'm not using the AC much, and a fresh pan of Rotella synthetic seems to have boosted the MPG by about 1 mpg.

All of my numbers are hand calculated, and my overhead guesser is *usually* within +/- 1mpg.

It's been said before, but I'll say it again: these trucks are living, breathing creatures with their own personalities. Treat them well, and they'll treat you well.
