MPG expectations

[Blanco Willys]

Gas… yes that’s it.

With 1200 miles on my stock 2022 JL Willys the 2.0 Turbo it gets 20.7 mpg combined city highway. It's still breaking in with Winter gas formula and factory MT tread tires that lowers the mileage. I've only put in 93 octane premium since the manual recommends that for best performance.

I have done a 7600+ mile trip so far this year pulling a camper and wheeling and have an 13.1 average for mileage. This is lifted on 37s bead lock wheels loaded down. I drove round trip from Yuma Arizona to LA California and back the other day and averaged 16.9 mpg for a total of 670 miles.

I'm hoping for 18 plus if possible. The 35's won't help but who knows.

I was averaging around 19mpg combined with a totally stock '19 2.0T eTorque. I would not be surprised if your combined average is around 16-17mpg.

FWIW, I've put ~600 miles on my 22 JLU Sahara, and have averaged ~13MPG around town, and ~16MPG on highway trips, this far. I think feelings are mixed, leaning to annoying, for the start/stop feature. I shut it off when I remember to do so, but don't always remember to.

Just completed a ~400 trip this weekend, cruise control set at 65 and averaged 20MGP. I didn't go into this Jeep experience with any particular expectations about gas mileage, so I'm happy.

So, 300 miles on her to this point. Mainly intown driving and she is showing 18.1 mpg.
2.0 Turbo, 2 inch lift, 35 tires.

I had a totally stock '19 JLR 2.0T eTorque. I now have a totally stock '22 JLR 3.6 eTorque. So both with the same K02s, 8-speed ZF and both with the Rubicon gears. I used premium gas in the 2.0T. I am using regular gas in the 3.6L. It will be interesting to see what the mpg differences are between the 2 engines.

JLR with about 4,000 miles, V6, Premium fuel, Use ESS.

Living in San Diego, I'm always up and down hills, and very little flat ground. I keep it to about 75 on the highway, and have a 50/50 mix of city/highway driving.

I average about 17.5MPG

Picked mine up a month ago, have 1200 miles on her and average 19MPG. 2 door 3.6l stickshift. I drive to and work in Manhattan every day.

What differences do you notice if any between the engines with both having etorque?

Would you have chosen a different engine if you could have?

I get asked this a lot.

Reliability seems to come up a lot. First off, I think BOTH engines are very reliable. I would not hesitate choosing either engine. I feel there is more of a reliability difference between the 2 different Start-Stop systems. Personally I prefer the eTorque start-stop system. Someone at FCA once told me almost 40% of warranty claims are ESS battery/charger related. I feel the ESS start-stop system with the smaller 12V aux battery is the Wrangler's Achilles heel. I think that ESS system is more problematic and more likely to cause check-engine lights then eTorque. There are plenty of threads about problems caused by the smaller 12V aux battery. I would highly recommend replacing both the main battery and the smaller 12V aux battery every 36 months like clock work to get ahead of any potential issues a bad battery might cause.

The main difference to me is the difference in how each engine makes power and each engine's driving characteristics. The 2.0T makes more torque lower in the rpm band and it is very noticeable. The extra torque helps get the heavy Wrangler moving with less effort. The extra torque helps hide the weight of the Wrangler, making it seem more agile. The 2.0T is a much more "sportier" feeling engine. The 2.0 turbo does have slight turbo lag under certain circumstances. Maybe about 5%-10% of the time when driving. The power delivery is not nearly as liner as the naturally aspired 3.6 engine.

The 3.6 engine is much more refined, smoother and makes power very liner like. Power builds smoothly as RPMs raise.

Both engines are a very good match with the ZF 8-speed automatic but I think the 2.0T is a tiny bit better. The programming is very good with the 2.0T.

Then there is the difference in NVH or Noise, Vibration, Harshness. No question about it. The 3.6 is smoother and quieter.

I honestly would not over think it. You will be good with either engine. I loved the 2.0T and would have ordered it again, and I wanted to. Unfortunately the 2022 Rubicon was not available with the 2.0T "and" eTorque. I dislike the ESS with the smaller 12V aux batter enough to choose a different engine to avoid it. I had to order the 3.6 to get eTorque with my 2022 JLR. I have absolutely no regrets choosing the 3.6 this time around. I do miss the extra torque of the 2.0T but I am enjoying the added refinement, smoothness, quietness the 3.6 offer over the 2.0T. I would say those are the main tradeoffs.

The 2.0T is supposed to get slightly better MPG. MPG wise it will probably be a wash? I used premium gas in the 2.0T. I use regular gas in the 3.6. Whatever added MPG of the 2.0T will probably be a wash cost wise as a result. I should know more once I put more miles on the 3.6. I have a nice road trip planned this month so should know more soon. It's also kind of bad timming for a long road trip. I can't believe how expensive gas has gotten this week. I am cool though...first world problems.

That settles it. I am regearing. I've done the math on gas difference today (my mileage vs old and new prices) on a couple trips I plan to take. It wasn't enough difference to stop me from enjoying life, but my trailer isn't here yet and I know that will drag it down. Mine will be close enough to your setup that I can see the regear will start paying for itself...and I will like it better. Less throttle for the same acceleration is likely the winner.

You went 5.13s? Was looking 4.88s. My trailer is estimated 1200 loaded.

Thanks for the great response.

What situations would you say causes the turbo to lag? Is it just randomly?

Its hard to test drive both back to back with limited inventory in my area. I was able to test drive a 2.0 JLU Sahara and I felt the noise difference you were referring too. It sounded like a sewing machine. My current and first jeep I have owned for two years is a 2013 JKU Sport with the 3.6 (it also sounds like a sewing machine though due to it having the ticking engine noise issue).

I then drove a 2021 JLU Rubicon. To me the Rubicon felt so much "quicker". I think the main reason I felt that is the throttle response to pushing the accelerator was immediate. Whereas on the 2.0 I had to press about a half inch before it seemed to register. I don't know if thats stock or the Rubicon had been reprogrammed with a comuputer.

I read a lot that people seem to think the 2.0 is "peppier". Is that just the opinion of those with 2 door jls or for all? I also wasn't sure if it was my driving style that was at fault for not getting the most out of it with my test drive. I am use to the slow linear acceleration so that is how my foot handles the throttle, slowly easing the pedal down as I pick up speed.

To get that peppy experience are people just mashing the pedal to get that sensation?

I am assuming you have the two door versions. Have you heard similar thoughts to what you expressed for the 4 door jeeps as well?

The lag only happens maybe 5%-10% of the time you drive. The turbo needs time to spool up and build boost, that is the slight lag. It does not happen often. An example is when you might be driving really slow, and the turbo is still spooling up, and want to pass someone. You hit the gas and the turbo needs a split second to spool up and build boost. There can be a very slight lag or delay before the boost builds up. It is a non-issue 95% of the time.

The Rubicon has lower gears than a Sahara so it is quicker even with the same engine. Your best bet is to try finding 2 Saharas or 2 Rubicons with the same engines to try.

I feel the 2.0T feels a tad quicker because of the extra torque. Torque is what you feel pushing your back against the seat when you hit the gas. I own 2-doors but have driven a LOT of both the 2 and 4 door. Both the 2-door and 4-door 2.0T feels a tad quicker to me than a 3.6 with 2-door or 4-door.

You notice the peppier feeling of the 2.0T when boost is on. The extra torque is very noticeable.
