    Winter-blend gas negatively impacts fuel economy too.

    But I just put the new Flowmaster cat back system on and it sounds so good. Lol.

    It's a 4 door Rubicon that he freely admits to driving 85+. His mpg doesn't surprise me at all.

    I have a JLURT with 4,500 miles and with mostly all city driving I average 20 to 21 mpg. I got up to 24- 25mpg on the hwy with speed between 55 to 60mph and get 21-22 mpg at 65-70mph. My first tank of gas I got 16.5 mpg and it got increasingly better with every tank.

    Something is off.

    Why are comments such as this so prevalent on these forums? Is it the sort of "If ya don it, git out" approach taken should someone criticize something in America?
    Why is unreasonable to complain that a vehicle's fuel economy is significantly different than what it is one the sticker? Why is it not reasonable to ask other people what their experience is.
    Seems a very strange attitude for a forum build around discussions of vehicles.
    It's basically all the Jeep forums, not just here. I just don't understand when y'all get so triggered about it.

    The moment that turbo spools, your fuel savings is gone. Turbo's are not great for mileage, they're only good when they're not on.

    Take your Jeep out on the Autobahn at 140+ kph and let us know what your fuel economy is. I'm genuinely curious. Of course I think you do have a different bumper which would effect aerodynamics.

    Why would I want to do that? The Jeep is certainly not made for high speed driving. I had my JK once at 95mph and it seemed it could fly apart at any moment. Not to mention, the front end was very light at that speed.

    BTW; While there are unrestricted areas of the autobahn, much is actually limited between 100-130KPH. 120 is typical in my area which is about 75 MPH. On my work drive, there is no unrestricted sections. Not that it would matter. Traffic is typically so bad that you would never have a good run.

    In the US, I normally only drove my JK (2015) with about 65 MPH. I would get about 19 MPG. That Jeep cost be about 200$ every 2 weeks in gas.
    I am still awaiting of my diesel jl rubicon. I really considered the 2.0T as well, but we don't have the mild hybrid part here, so you lose the main benefit to taking that engine, in my opinion.
    Seems most folks return about 21 MPG with the 2.2 Diesel. As I do not drive with a heavy foot, I would also be complaining I was returning significantly less than that.

    I know the Autobahn well. I was stationed in Germany! I think people were saying that to the OP because he said he regularly drives 75-80 mph. I personally just set my cruise at whatever the speed limit is.

    I have the 3.6, but I will say this. Last weekend I drove across Alligator Alley (75 miles of straight flat road), I set the cruise at 78, and watch my computer MPG drop to 15.3, I'd bee usually around 18's in my daily driving.

    On the return trip I set it the cruise to 74, and achieved 17.1 on the return. So, anything over 75 in this brick is a major drop.

    I agree with everyone...

    I have a 2018 Ford Raptor and a 2018 JLUR with 3.6 on 35s.

    With both vehicles, if I drive 55-60 it will get 16-18mpg on the highway, the minute I go to over 65 it drops a bit and 75mph I am in the 14s with both. it is like driving the front of a barn through the wind.

    My Jaguar F type V8S will do 25-28mpg on the highway at any speed.

    Par for the course with the tiny turbo engines. You're not alone, other automakers are seeing the same thing. There've been countless articles written in the media about Ford's little EcoBust engines and how they do not achieve the promised fuel economy.

    Power = air+fuel. Displacement doesn't matter. It takes X amount of fuel to make Y amount of power.

    How do you like it? I assume you mean the F150 version? We can get the Ranger raptor here, but not F150 at all. Too big for our roads in any case. The Ranger I think is a 2.2L Bi-Turbo which is supposed to be cracking engine.

    Don't have a F Type, but our Jag XF sportbrake returns about 45 MPG on the highway. My wife is pushing for a convertible F-Type.

    I can't speak for the rubi since I only have a sahara, but I average about 21-22 with the evic display. I'm currently on 2.5" of lift, 35" Milestars, with a stubby front bumper and winch. Gas mileage on the 2.0L drops significantly between 70-75. Everything has been calibrated for the larger tires and my speedo is correct. High speed in these rigs really affect mileage but 13 seems low even with the 4.10 gears vs. stock sahara gearing. I would folow the suggestions and maybe reset the TCM and go from there. I drive it like I stole it but still manage good mileage.

    I get the argument that one should not expect close to the ideal MPG if you are driving that fast. I think they use a speed of like 52 MPH or something like that.
    But what is often commented is that if you care about MPG then go buy this or that car, which, in my opinion is a nonsense comment and certainly adds nothing to the discussion. I think if you drive in a reasonable manor, with a unmodified Wrangler, it is reasonable to expect something at least approaching the claimed economy.
    If you take the extremes: Some people said they only got like 14 MPG, while I have seen some people claiming 23. I have my doubts on that, but anyhow.
    If you take a gas price of 3$ and then assume you own the Jeep for 75K miles, that's $10200 over those miles. So, it's not chump change. Of course, here, the difference would be almost double due to the cost of diesel vs gas.
