Terrible 2.0 gas mileage?

[Thinman]

3k miles, 2.5" + 37" Pats and have settled in right at about 15mph. I have a led foot on the highway and actually get better MPH in the city.

I have the 2.0T in a JLU Sport. I added Rubi take off wheels/tires and I am still getting 22.4 in mixed driving. I usually drive pretty smoothly- no hard take offs or stops.

A few observations:

1. We usually just cruise around town and to a few other local cities between 25 -45 mph and were over 28 mpg
2. Today we did some highway driving. Mileage dropped to 27 mpg. So looks like I am getting worse mileage on the highway than running at 25-45 mpg in the city. Still noticing with the new 33" tires, that the jeep will not cruise in 8th gear. Goes back and forth but mostly in 7th. So still feel the 33" tires will reduce MPG but maybe not as much as I thought!
3. We burn 89 gas and obviously have about as flat as a terrain it gets.

I have the 2.0 with e torque and I typically get 20 MPG all the time. Currently have 9k miles on it. I don’t drive that gently In the city and commute on the highway about 5 miles each way. I set the cruise control at 73 everytime as well just to give you an idea.

I added a roof rack to my 2.0 T jeep this week. Mileage has been down about 1 mpg so far to about 21.5. I'll update this after I have put some more miles on it.

Just bought a JLUR Saturday.

We were getting over 22 this whole week, until yesterday, and my observations:

1. Idling is bad. Fast food, waiting on the spouse, etc.
2. Cruise control is your friend. As much as you can.
3. Start stop, not "city driving" is your enemy. This includes traffic.

25.8mpg running down 75 South through Atlanta at about 73mph. I got 27.3mpg on rt. 411 after 120 miles @ 40-60mph.

Mine isn't what I’d hoped for. all stock Rubi with stock mt’s. 60 foot elevation around here and I don’t really drive it hard. I get around 18.5 on the hwy. 15 something in town. I realize mpg’s will drop significantly above 60 But I was hoping for better. I’m at 6k miles now and no real change to mpg’s.
Lol My first Jeep, 2007 Rubi 2 door auto, did a little better on the hwy.

just got 450miles on my last tank... i only have around 850/875 miles on the jeep. I filled it up on 93 octane and i would say its 50/50 when it came to city and highway driving. The only thing ive done to the jeep is put the flowmaster axle back exhaust which i doubt would have any affect on MPG.

If you're running on flat terrain during highway driving, I don't think your transmission should be searching much between 7th and 8th gear unless you're running very low air pressures and/or you're running into high wind.

I have a 2018 JLUR, 2.0 with stock suspension and tires, steel bumpers, and winch(just added less than 100 miles ago)

After 1300 miles, ~600 highway the rest city, I’m averaging 13.4 MPG! (calculated by the Jeep) One of the main reasons I chose the 2.0 was for the fuel economy but this seems like a 3.6L average. No, I didn’t expect the stickered 22-24 but I did expect it to be in the high teens and maybe over 20 on the highway.

What are you averaging? Thanks!

Do you still have the same JLUR? What if anything happened with the mpg?

I've got 605 miles on my '21 80th Anniversary. The last fill up was 13.25 mpg calculated (I don't trust going by the dash computer). Mostly local driving. 87 octane. Yes, still in engine break-in phase I guess, but I'm a little concerned. I was doing the varied acceleration thing for engine break-in so maybe that has something to do with it. Curious to see what happens on the next gas stop.

Wow, that's low. Stock?

My wife's '21 Two-door JL Rubi just showed up with the 2.0 -- first fill up average was 19.2. Every option group checked basically outside of the advanced safety package. We have the steel bumper group, and the KO2s.

My '21 diesel JTR with a tent (stock otherwise -- but the tent likely drops it 1.5 mpg) is averaging around 23 mpg after 2000 miles. It has the stock Wildpeak MTs.

FWIW, I had my '19 JLUR for almost 30,000 miles. We averaged around 18-20 mpg the entire time, even w/ 37" KO2's and small lift/winch. Mostly city driving. 2.0 Turbo.

I live in a valley -- when I go up mountains it drops significantly except for the diesel.

Let me do the conversion...

~10.5l/100km = 2.77 galons per 60miles

=

21.6MPG

Using 87 fuel only

I get 10l/100km when I'm on the highway
I get 11l/100km when I'm in the city
I get ~11.5/100km when I'm in 4hi out on the forest roads climbing in the mountains

My odometer will hit 10,000km this week (6,000miles)

My milage has not changed noticeably since adding lift, new bumpers, winch etc.

16 to 17 max with mostly in town driving. Not lead foot, but not a slug either. Run mid grade gas 89 octane.
