MPG Comparison

So we all drive jeeps and obviously not for the mpg. I think it would be interesting to see what different set ups are getting for mpg. Post up your engine w/ mods, gears, tire size, and avg mpg at roughly 60 mph. I think this would be some good info as a comparison for people looking to upgrade and possibly make some changes.

I'll start, I'm still working on it and next on the list is gears...

3.6 pentistar (stock)
Stock 3.21
35/12.50
16 mpg
 
2008 JKUR
3.8L
35x12.5x17 Nitto TG
5:13
11.9 mpg

Thinking my cal is off

Avg - (16 - 19) MPG over 14000 miles
@ 60mph, around 19-20 on the highway.
I've used fuel monitor since day one,. now its summer I have the soft top on and i normally see a little decrease in mileage.
 
2015 JKUS
3.6L - Manual
Stock - 255/70/18
Gears - 3.21

MPG 20-22 Avg.

Looking to upgrade to 33" tires in the relatively near future and expecting to drop to 18-20. Might also be interesting to note lift and trans type to see what differences the pairings make.
