Been on this forum for a while now, got a new-to-me Jeep last winter and thought i would show you my to-date best one way trip reading.
Mods I have done:
Roof rack removal
Factory Up Country package with light weight 16" alloys
synthetics in diffs, synthetic oil, partial grill block (in winter)
Tuned up and running like OEM
I'm at 21 MPG average since owning the Jeep with a lot of that coming in the winter months of Colorado.
