Rubicon Owners... my friend is desperated because his 2005 Jeep Rubicon is giving only 15.8 MPG. It is stock from factory. Stock axles, Stock tires. No heavy bumpers.. Completely stock from Dealer.

Is this normal? It is a 4.0 with an Automatic tranny.

Thanks in advance.

Wrong vehicle if bought for gas mileage! It's a Jeep-shaped like a brick. Gas mileage is not it's strong suit-having fun wheeling it is.

I don't own a Rubicon but I think that is pretty good mileage.Might get a little better if it was a manual.I am lucky to see over 12 but no longer stock either.

Does an 05 auto have overdrive? If not, I'd think that's about as good as it's gonna get. My buddy says his stock TJ gets about 20 on a freeway trip, so I would think mid teens aroung town would be ok.

Yes the Auto tranny is an 4 speed overdrive. We are talking about a stock Rubicon. Stock Gears, Stock tires/wheels. So i asume this normal...

I get about that with my Rubicon around town and about 18 on the freeway. Offer your buddy a good price for his jeep...maybe you'll get lucky.

thats not normal. My 84' CJ7 with 35's and a fuel injected 4.2 L Inline behind T18 gets 18-19 MPG! :smokin: I think putting a stick behind it would fix some of that

sorry PizzaFarno but it is normal. My best friend has a stock Rubicon that he put 75,000 miles on from the time that it rolled off the dealership lot brand new. The whole time he got only 15-18 miles per gallon. He is german and had a log book in the truck where he would record the amount of gas used and miles driven every single time he filled it up. Yeah, they are crazy for numbers! Anyway, best he could do on a long freeway trip going around 65 was around 18. Mixed use was about 16. My jeep is at about 13. Not a good choice for a gas mileage truck. But heck smoke 'em while you got 'em!

oh yeah, I also had a roomate with a pretty much stock Toyota Tacoma TRD running 31" BFGs and bone stock motor. He was happy to get 17 so for what it is worth these trucks might be small but a diesel F350 is cheaper to drive on gas!

04' rubicon hwy best approx 16mpg thats when all stock (auto) its gotten worse
97' tj 4.0l 5 speed 33" swampers 4.56 R&P hwy a bit above 17 mpg @ approx 2500-2700 Rpm

94' yj 2.5L 31" tires best I ever got was about 12 MPG (its now being put back togeather)

notice a trend?
They all say Jeep on them
And

Wait for it

The gas mileage suks.

Edit: it think you'll find most guys worrying about gas mileage think that lugging (below power band) the motor will make it better, its opposite of that. The lower the Rpms the more the throttle needs to be open to maintain the speed. especially on a 4.0L

Ive never had a new age jeep(im orginal owner of CJ), so i guess the new ones are worse than the old ones on gas!

Sounds right to me, i have a 98 TJ daily driver, stock, standard trans( w/ OD) . I get about 16 mpg on the highway, i get a little better on back roads. Contrary to popular belief jeeps get worse mpg on the highway. Don't compare it it any other vehicles other then stock TJs. Apples and Oranges. My YJ crawler 4.2l Carbed, T-18 (no OD), 35s, 4:10s only gets used on back roads and has the same mpg as my TJ on the highway, sometimes even better if i really try to conserve gas.

Id say its about normal I get 12-14 and I mainly drive on surface streets and mine is a pig (02 TJ 4.88s, 4.0 5spd) with all the junk..ie winch etc. But I would again say to him that its a rolling brick if he wants great MPG get a different vehicle.
