You need a lift kit and bigger tires.

I’ve seen 85mpg right after a reset and going down a mountain. LOL

23 Willys ZF, all Factory, about 4500miles.

21.5mpg at 75mph using CC
19.5mpg at 80mph using CC

Factory MTs at 45psi. No hyper-mileing behavior.

I bet with low rolling resistance HTs, I could get 21-23ish.

My engine must have broken in recently or something (11,000 miles on JTR). I’ve been averaging 17.5+ MPG lately with mostly around town driving. Current average at 19.0 MPG which is amazing for my rig.

For the better part of the first ~8,500 miles, I averaged ~15 MPG.

Tires have a huge role in mpg as do the factory bumpers and such.
i used to do 21-22 easily until I went with wider A/T tires and heavier bumper that allowed the front fender area to act like big wind scoops. Now it's 19-20 in good weather if I'm careful and wind has a lot bigger impact than it used to. I saw a 2 mpg drop just taking off the H/T tires and going to A/Ts.

Both of mine, the 2020 and this 2022, jumped up a bit after I crossed the 6,000-7,000 or so mile mark.

I was getting around 21 mpg with stock 255/75r17 Firestone mudders. I thought, "wow, this is great". I connected my analyzer to it and noticed that the tire size value in the computer for those factory tires was 32.57". I measured the tires and they were 31"! I think a little trickery was used from the factory to get the mpg up. I reset the tire size to 31" and lost 1.5 mpg. I replaced those tires with 285/75r17 tires and re-entered the correct value for the new tires. Now I am getting 18-19 mpg. My point is that what you think you're getting may not be what you are actually getting!

Drive about 14mi each way daily, been 17.5ish average. 20+ in assuming must be mostly highway. I never get over 20 and everything is stock, no lifts or big tires or anything

So wouldn't odometer be wrong too? That sounds like a big issue

 

[AverageJoe]

Most definitely.
