MPG Comparison

[REKLESS-RED]

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...

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.
