Stock 04 rubicon. I have seen anywhere from 15.something up to 18.something based on how and where I was driving

I'm currently living on the Kentucky Indiana border, between Owensboro and Tell City. Here for work for another few months, than its back to So Cal. Fun to find some local jeepers.

Stock '03 Rubicon with 32" BFGs.

My record so far is 20.38mpg. Last tank was 17.2mpg. I typically get 14-18 depending on how much highway driving I do.

Driving with ODBII & Torque showing the current live milage helps a lot. You get to see how the Jeep is performing in real time. I've been able to learn where my shifts should happen and that I should use 5th gear to cruise more often.

I have high hopes for this current tank. I filled up in Leadville and drove 100 miles / 5,000ft downhill to Denver and only used a 1/4 tank!

Sadly, I ONLY got a little over 18mpg on that tank. But I finished it off with mostly city driving. Not my best. What does surprise me is that I can take a 25-30 mile detour/shortcut over a very slow rocky mining road and still often average 13-15 mpg on that same tank. Keep in mind that I am still at stock height with 32" tires.

Just to add to my statement above, I filled up today after a tank that included about 100 miles of mountain highway driving, 30 miles of Denver flat highway, 60 miles of city, and 30 miles of rocky mining roads mostly in 4L that climbed up 3,000 ft and back down before hitting normal roads.

16.64 mpg

Are you guys calculated it yourself or using the overhead console read out? I'm getting about 15 mpg city and highway combined. Just calculated after killing a full tank. Honestly, with AWD and a 4.7l V8 I was expecting worst.
