Looking to buy a Rubicon

Hey guys I'm new to the jeep thing but I drove my cousin's 06 Rubicon and love it and now I would like to get one, but first I have a few questions.
1) What kind of MPG's can I expect from a stock rubicon with a manual transmission?
2) What is the fifth gear ratio in a five speed and what is the sixth gear ratio in a six speed?
3) Off the topic of Rubicons, what factory axle ratios are available in other wranglers?
Thanks

i think if you go hardcore offroading go with a ruby if not go with a sport or an x.. same engine and not much luxury in all of them.. I just picked up an x, with all the options.. but options are bare minimal.. I get 15mpg average.

from what I have gathered the rubi comes with bigger axels and wheels with track loc and abs.. correct me if I am wrong..

I have an 06 X and I love it. Wheels with the best of them! The Rubicon comes stock w/ lockers, 4.11 gears inside Dana 44 front and rear, rolling on 31s. The X and sports come w/ d30 front d35 rear or d44. Same engine throughout. I would have gotten the Rubi but I figured if I break my axles I'll upgrade then. I always upgrade when I break stuff.

Rubicons get worse MPG than any other wrangler, because they have 4.11 gears on 31s. 65 mph=2600 rpms...

My rubicon (which is a stock 05 6spd with 27k) gets 16.5 mpg BEST, top on, and 11-13mpg with the top off. In the WV mountains, I got 14 with the top on going under the speed limit.

The 6 spd in the Rubicon is geared higher than the 5 spds, even the overdrive. You will actually get better mpg with 33s and stock gearing than with 31s (or so Ive been told).

Check out www.RubiconOwnersForum.com if your interested in a Rubicon. Do a search on the 6 spd, youll find more than you bargained for

The overdrive is lower in the six speed, not higher.....see Scoob's post above.

Most likely you will get worse mileage with the 33s and stock gearing, not better.

But what do I know?

I meant lower Said it the wrong way, but what I said is still true. Stock Rubis are geared just a tad low, but its good if you plan on adding 33s or 35s, maybe 37s but thats a stretch. Ive heard the 411s arent bad on 31s with the auto.

Take a gander at rubiconownersforum for more specific Rubi info, or feel free to pm those of us with Rubis.

On average mine has stayed the same. When on 245's I got between 15-16 and now with 285's I still get between 15-16
