Jeep Rubicon Gas Mileage?

I just bought a brand new 2006 jeep rubicon and it is getting 10.5 miles p/gal. I don't expect it to get the MPG stated on the window sticker (15 city) but 10.5 mpg on stock a stock vehicle??? I took it to the dealer and asked about a break in period and they told me it could be possible, but if something was wrong with the emissions that the Check Engine Light would come on. So of course, the dealer was no help.

How many miles? Once it breaks in, it should get better a little. Don't expect any good mileage when something is brand spanking new.

How many miles are on it. What methode of calculating the milage are you using?

Stick-auto?

These things are not great on gas, and in all city driving, I think you close.

I got a constant 38mpg in my Rubicon when it was new, it only went up to 40 after I broke the engine in.

Maybe you meant 3.8 and 4.0

I have just over 1000 miles. It's a manual tranny. Its also an unlimited if that makes a difference. I'm hopeing that getting a chip, intake, and throttle body spacer will help a bit. The method used for calculation is the ammount of miles driven from fill up to gas light coming on, divided by the ammount of gas it takes to fill back up. (not verry scientific but it seems to work)

Save your money for fuel, or a lift. The mods you talk about will not get you the money you spent on them back, and your jeep will not get any faster!

People despise gas milage threads on this forum, not the best way to start off. That being said, drive like grandma with the doors and the roof on, accelerate very slowly, always use the highest gear possible. I get 16-19 w/ my 5spd, but I also don't have an unlimited. Realize you are not going to get good gas milage in a brick on wheels.

He was joking.

Ur new so I'll cut you some slack in the flame dept.. .only cause the question is about a break in period...

But MPG threads around here are a dime a dozen and usually end up Blasting the guy that asked

did the dealer run diagnostic on it? when new mpg can be a little bad.. but it will get a little better.. A LITTLE.

i had the same issue on my audi.. turned out it was running rich. but from what i read on these forums.. tj = bad mpg.

I also have an '06 manual, and I'm getting around 13-14 (guesstimate). I haven't sat down and calculated it because I'm afraid to. I traded in a Sport with 3.73 gears and it got around 16-17 city driving. The rubi's low gears really take a toll on mileage. But it's got some good pickup and torque compared to my old TJ.

Lots of positive feedback about the Edge Trailjammer kit for improving a couple mpgs. Unfortunately they don't make the kit for 05-06 yet.

Write them and ask for it! http://edgeproducts.com

O.K. no more about gas mileage! I definately did not buy it with fuel economy in mind. I'll get over it.
