Rubicon 2020, 2.2L diesel
Drove my new Rubicon to the northwestern part of my country ( Iceland) few days ago. I mostly spent my time on around 50 to 70 mph ( legal limit is only 60mph ) on the roads here. Drove total of 800miles during the trip , over mountains, very bad tracks and dirt roads. Surpriced of how little fuel it uses. The trip computer gave me 7.5L/100km or somewhere close to 30mpg.

Despite what the Fiat detractors would say, the 2.2 Multijet II is a very good engine for the Wrangler, with high torque / power and low consumption.

Actually, it has been proven more reliable than the previous 3.0 EcoDiesel generation so will see what happens with the new 3.0 one...

I drive pretty slow and get about 8.5-9l on my Rubicon.
The 2.2 is so much better than the 2.8, which was ridiculously slow and unrefined.

My 2.8JK averaged 9.88L/100 over the time entire time I had it.

I've done a little over 7,000km and am averaging 11.7l/100km. Most of my driving is in traffic and my right foot makes lead seem like a feather. I'm also running 35s. I can get mid to low 8s on a highway trip at 110 - 120km/h so if I dropped some speed I could probably dip under 8..

Guys, you most probably all know the only proper way to measure your consumption - refill up to full tank, reset TripA/B counter , during next refilling again up to full tank check the liters and divide with kilometers on the TripA/B counter. The board computer is not very accurate and more optimistic usually.
Using this technique, spending in town/on highway approx. 60/40 , and doing off-road trips I get around 12 l/100 km. Of course the consumption dramatically drops on the highway if you’re going 90-110 km/h without pushing it hard, but I’d really need to reset the consumption meter before highway trip to see 7-8 l/100 km - I’ve never seen less than 10, most probably because there’s always some nice wheeling in the end of my trip ))). Off-road consumption is above 20 l/100km I believe in the moment, or even more. I should also mention that this engine is providing not the best dynamics, so I often have to push it especially for overtaking, entering highway, etc.
I’m quite happy with my choice so far, but I’d appreciate larger fuel tank, less AdBlue consumption and less noise :CWL:
P.S. My Jeep's got some extra weight with steel bumpers, winch, front skid plate, RSE power steps. I run 315/70r17 tires, and I’ve got the pedal boost adapter - all these factors contribute into consumption as well I believe.

How is your AdBlue consumption?

I am close to 5.000 kms and its around 70% left
I have already added first 10 liters at less than 3'000 km mileage... And during my first service at 6'000 km this february they added more (I don't know how much exactly though). A lot of people with this engine experience a high consumption of AdBlue for unknown reason. Since I have 2 more diesel cars in the family I can't blame fuel or something else for that, as I added AdBlue for the very first time to my wife's X3 30D at around 25'000 km mileage 😎

Yeah that sounds like a lot of AdBlue consumption; maybe if you do short trips or drive much in the city?
I would expect more like fill in the tank every 20.000 kms or so... so lets see!

Well, it's kinda strange to me too, but some people here from the UK and other countries also observe the same. You might be right about short trips, on the other hand we have a highway all along the island, and it's very convenient to use it even to get from one part of the city to another, so I'd doubt this is the reason. And again other cars do not show any unusual consumption. Anyways, since 10 ltrs of AdBlue cost around 12 euro here I don't mind, it's just a bit surprising compared to other vehicles I own/ed.
