Just got back from a 600 mile trip with my 2018 early build JLU Sahara. mixed driving maybe half highway 65/68 MPH, 22.3 MPG with trip set, 22 even with math. Not bad for a heavy brick, 3.6 with ESS and auto tranny.

ESS stopped working on our 2015 ESS V6 3.2 Cherokee Trailhawk 6 months ago, mileage went up couple MPG! ESS needs service light bugs me a bit is all, don't plan on having it fixed very soon!

Go Jeep!!!

I want to know what kinda gas mileage the 2.0T BSG gets in a city with a lot of long red lights lol.

I can go a month without touching a freeway because the nearest freeway is the 405.

I am sure if you "gun it" then there is more thirst from the busy pistons . Living in Canada do you set your Jeep to miles? I know many older Canadians of course measure distance and mileage by miles . I honestly think it was a mistake to convert Canada to the metric system considering the largest trading partner and a giant of a neighbor has been running all business in the US measurement system. I just find it little confusing in Canada how we go about the business of measurements.I think Canada is probably the only country in the entire world where new cars will have available settings in both miles and km on the tachometer . Yet we still buy "2 by 4 " lumber , in construction its still mostly feet and inches , in supermarkets it's still pounds etc. Well , that was a national gift of the old Trudeau guy and even now we still have to deal with the Trudeaus .
No, most of my friends I converse with on a daily basis live in the US, it's a recycled picture I took to send to them, we were also having a mpg conversation.

I drive kinda hard, have always had a Wrangler so mpg doesn't really matter to me, a tank will usually last me over 2 weeks. I remember when I had my YJ 30 years ago, I would drive from Scarborough to Yorkdale and back that was 1/2 tank of gas.

I am 50, my brain still works in Imperial, hopefully young Trudeau doesn't sneak in for another term then we are really going to get a plastic straw up our Butt.

I for one would like to welcome you to the internet! You don't need to sign your posts as we all can see who made the post.

As for engine choices, the simpler the better.

I'm not sure if rocket is what I would call the 2.0t. I'd agree its def a big difference vs the 2.5 but vs the new 3.6 I'd hardly call it rocket faster lol.

I wanted to like the 2.0t but low range and from a stop felt like I was driving my 4cyl yj until the boost kicked in. It would scoot once it got boost but it was a easy pass for me.
I should have been more clear. I was comparing my current 2.0T auto with my previous 3.6 with 5-speed automatic in my '15 JK. The new 8-speed transmission definitely has a lot to do with how much better the JL is over any of the prior Wranglers. I wonder if you drove a 2.0T that was running right? I have to respectfully disagree about the 2.0T feeling like a YJ 2.5 until boost kicked in. It's not even close. The 2.0T easily feels more powerful then the 4.0L the Yj had. The extra torque transforms the driving experience.

The good thing is there are more then one engine choice and everyone can buy whatever floats their boat.

Have a totally stock Rubicon 2.0 BSG. On average I have been getting 19-20 mpg driving 80% bumper to bumper traffic with the A/C on. Recently my mpg seem to be going up for some reason? I have seen 21-22 mpg in mostly city lately with A/C on. Highway with A/C on all the time is around 25 mpg now. Tire pressure is 36 psi.

As a reference my '15 Freedom Ed with 3.6 and automatic got about 15-16 mpg under same conditions.

I drive mostly city with lots of red lights, in and out of downtown. If you can leave the ESS on and it doesn't bother you, the 2.0T BSG is the right one for your application. I am close to 22 mpg doing mostly city driving.

Eerily familiar to the Ford ecoboost saga. Real world mileage is no better than a 5.0 in their F150s, literally almost exactly the same when logging long-term averages, but you pay $1,800 for the engine option and also have way more things to go wrong. (We've owned both, and had turbo issues with the ecoboost). Do people not use calcultors?

It's why I decided to skip the 2.0 in our JL. KISS applies here.
If anyone used calculators for the BIG PICTURE they'd see there's at least an argument for maintaining the "Clunkers" that already exist vs the "carbon footprint" of constantly pumping out new vehicles.

But we're consumers, and we're supposed to consume.

We also think use of resources STARTS when we take delivery of our new vehicle. We don't consider the factory that was built to build that vehicle, the factory workers driving to work everyday, the cost of hauling our old vehicle to the scrap yard, etc.

We'd be ahead to employ those people to crank out quality reman parts for vehicles already in use, but that solution means less $ and less consumerism.

*drools* I get about 14mpg city.

I like the way you think! Unfortunately cars aren't built to last for more than about 20 years. There's dozens of bushings and rubbery parts that will wear out, not to mention the drivetrain definitely isn't designed for it. Wire harnesses in cars are kinda laughable compared to the kinda wire harnesses I'm used to seeing on spacecraft too lol. The old "clunkers" have a hefty tilt towards survival bias as well.

If we were really, really concerned about ecology we'd probably all be driving something akin to a classic mini cooper or volkswagen beetle with a more modern - but still really simple and easy to service/replace drivetrain.

Looking at the fueleconomy.gov site to see how the 3.6 BSG did in the JL, and saw interesting comparison...

For the unlimited ...
2020 3.6 BSG 20 combined, 19 City 22 Hwy
2020 3.6 ess 20 combined, 18 city, 22 hwy
2019 3.6 ess 20 combined, 18 city, 23 hwy
2019 2.0 BSG 22 combined, 22 city, 24 hwy

Disappointed in the 3.6 BSG... was hopeful it would have been closer to the 2.0, or at least better than the 3.6 ess. Also not sure why the hwy number went down by 1 mpg from 2019 to 2020.

Rethinking a bit my choice of 3.6 in my 2020 JLUS... but I already have a 2.0 direct inject turbo in another car that had some issues, and wanted the ‘simplicity’ of the Pentastar. Was just hoping the etorque version was going to post better mpg numbers.

My 2018 JLUR averages about 18. Good gas mileage can be had on a Prius.

If you MPG makes you feel better just wait for PHEV.

Updated original post...

2020 2.0 with ESS (unlimited Rubicon): 21 combined 21 city, 22 hwy. Compared with 2019 2.0 with BSG: 22 combined, 22 city, 24 hwy

According to the Monroney, all of them are using the same EPA testing standards since the 2017 model year.
