what is everyones mpg with the i6?

That's about right.

13 or 15? that's horrible for the 4.0L. I was getting around 20 all of the time before I lifte mine. I'm running 36s with lockers and get about 15-16 miles per gallon now...

i get 15-18 with 33" tires

do u have an intake or anything? and how do u drive?

to the limit

ya my jeep gets abt 14 MPG and its a V6 3.7 and i drive normal.. lets put it this way.. my F150 6l v8 gets better MPG then my jeep

That doesn't seem right... I get 13-15 in my '94 5.2L V8.

ya i always knew that the v8 in jeeps gets better gas millage but i decided that that didnt make seance... i was wrong... at least the price isnt 4.50 anymore like it was...

13-15?? I know mine is a 2WD and lighter, but I'm averaging 20-22

i get about 13-15 mpg, i have 33'tires with 4.10gears. i dont drive crazy and i always buy top tier gas. try not to use the a/c that much and have a hard top so more aerodynamic.

I was getting an average of about 22 mpg with a 1994 Cherokee Sport 4.0L 4WD with a 5-speed manual transmission. I do mostly highway driving.

Mine is a 2004 Laredo 4 wheel drive and I get 20-22 mpg

I have a 2004 Grand Cherokee 4.0L automatic transmission 4X4, one size bigger stock tires rated for 50psi ( I put in 55). I drive it cruise control set 60 m/hr or 95 k/hr. Used to average 24mpg. Then I swelled the front plastic air intake with heat and pressed onto wood end roughly 3X5.to fit the opening fully at the side by the radiator. Average went to 28mpg. Then on the vacuum line that controls heat and ac air flows, I put a "T" and an extra rubber hose with an air filter so it allows a little extra air that the computer doesn't know about. Average is now 34mpg. Imperial gallons. This is always same 325 mile trip with 200-300 lbs. cargo, 2 adults and a dog. With tail winds it gets over 36mpg. Fill ups are right up the filler neck and calculated. Readout up overhead shows over 25 US mpg. But that is just what the computer can show.

If I'm going to get the same mileage from the 6 cylinder as opposed to 8 cylinder wouldn't be better off just getting the 8 cylinder and have more power ?

hey I get around 5 mpg in town with mine (4.0 auto 4x4)and we have changed all kinds of secers and can't fix it. It also cranks for a long time be for starting. Any ideas

I get 12 to 13 mpg regular driving. 4x4 all wheel drive sucks put 5 bucks in 23 miles later out of h Gas gas cost 2.49 gal so 2 gal took me 23miles

Most of them have a gas leake at the tank only when thier running might just be leaking all your gas away

I just got my 4.0 Wrangler 6-16-20. I have averaged around 18 mpg combined city/ highway/ off-road and have stock Michelin defender 235/75/15 tires.

I forgot to mention this is with 3 speed automatic with 3.07 gears.
