First of all, don't go by the dash ECO computer. It averages over the past 500klm unless you constantly reset it. Watch what it reads when you let it idle in the driveway for 20 min. Figure out your consumption the old way with pencil and paper. If you still get crappy mileage try a tank of Premium fuel. I see major gains in fuel economy running Premium.

HI Alexkarbo,

So how is the gas mileage now?

PS. Merry Xmas everyone!

I live in the Ottawa, Ontario area, and I run a 2010 Mountain Edition with aprrox 9000km on it now. Last time i was at the dealer, he told me to wait to approx. 10000 km for my gas mileage to improve. i mostly drive highway and usually get 11.7L/100KM. For the last week i've just been driving lots of short distances, and it went up to 15.3.

Now that the xmas break is over, i headed out on the highway again this morning like i usually do, and it dropped down to 11 in no time. And i rarely see the 11L/100KM on the dash. so there might be a bit of truth to the breaking in of a new engine. He told me to drive no more then 110km/h

I average 400 - 425 km on approx. 55 liters of gas.

Friends of mine who have the same jeep get approx. 500km on a tank. and they have a bit more mileage.

will keep you posted as the mileage goes up.

Don't forget to wave

The tank on my Unlimited is 85L. Currently at 78,000klm, I average 500klm between fill ups (approx 70-75 liters) running premium fuel, 35" tires and factory 3:73 gears. I never got close to that with reg 87 octane gas. I travel about 110 kilometers per day 100 of which is on the hwy at 80-90klm an hour.
As far as the gizmo on the dash, I've seen that go down to 6L/100klm while coasting downhill with 35s. I just depends when you last reset it and how you are driving at the time.

i've got 10 000 on my Mountain Edition with 3.73 Auto and i average 12.5l/100 km.

i haven't yet seen the 9 or even 10 on the gage yet, but it is winter, so i'm hoping to see it when it gets a bit warmer.

We have a 2008 Unlimited Rubicon. I noticed when I went to a larger tire, my fuel mileage suffered. I have used both the Hypertech programmer and the Flashpaq and my best mileage was 9-11L/100 km loaded with kids and gear. That was running on the BFG 32" MT's. At 150,000 km, I switched to a set of 33" Federal Couragia MT's and also installed Mopar Off-Road Bumpers. I am now getting 13-15L/100 kms and just passed the 180,000 mark.

I'm also using an AEM Brute Force Stage 2 Cold Air Intake and Jet Throttle Body Spacer.
