Does Jeep purposely design their vehicles to get 19 mpg?

I wasn’t complaining about the mileage my Jeep gets just making an observation based on owning 5 Jeeps over the years.
Would I like better fuel economy? Sure, but I know what I am driving… a brick.
Yes

I pretty regularly get between 20-24 mpg. BUT - I do not lead-foot in the slightest. I do not punch the gas. I don't jump off the line when the light turns green. I pick a lane and stay there. I pick a speed and stay there. It's not important to me to be in #1 pole position. My wife says I drive like an old man, of which I am. I don't have tons of un-needed crap (equals weight) in the bed or in the vehicle. My Freedom came with Kenda A/T 265's, I'm thinking of downsizing slightly to KO3 255's. Yes, I said that. I'm going smaller. I'll pause to let everyone recover from fainting or having to wipe coffee off your keyboards. Smaller tires = less weight. Less weight = better mileage.

But, Texas is also based on highways, freeways, beltways. There is not much city driving to be had where I live. The nearest city is Houston, about 40+ miles away. I hated going to that rathole every day when I was working, now that I'm retired I don't even like seeing that ugly skyline. Two miles from my house; freeway. Freeway all the way to where ever I want to be, which is usually just off the freeway. So I don't have a lot of local city driving to drag down my mileage.

Backstory - When I was a wee lad, my Dad drove a 1967 Caddy Sedan DeVille. 429 cubic inch 7.0 liter engine. Drank gas like nobody's business. While working on it with him one day, I punched the throttle 2-3 times. He silently went under the hood to the back of the car. I asked what he was doing. He said, "I'm looking for the quarters you just shit out the tailpipe.". Of course teenage me goes, "Huh ?" "You just wasted 50 cents worth of gas punching the throttle. Easy on the throttle.". From that day on, me and my friends said when ever some was punching the gas to be cool, "He's crapping quarters.". LOL.

I've been easy on the throttle ever since, I hate losing quarters.....

I get 18-20 average on 37s and heavy. I get 15ish towing my camper. At times I wish I was getting better, but then I remember what I'd be getting in the same conditions with a gasser and then I don't feel so bad.

I have often wondered why, with todays tech our vehicles (in general) still get such shit fuel economy. I'm sure part is due to regulations, part is due to greedy oil companies having too much influence.

My '24 JTR gets about 17 totally city, 18 mixed, and maybe close to 19 on straight highway around 65-70MPH. Factory 33" Falcon Wildpeaks. No hills here in South Florida.

When I bought this one as with all the others, MPG was not the decision-making factor.

Agreed. High mpg's was not a deciding factor in buying this vehicle. I knew what I was getting into; hence the reason I bought it as a retirement gift, not a work vehicle. But if I can eek out just a wee bit more.....it's a problem in my cabeza, I know....

I fully understand. I am, well, semi-retired in that I still support about 3 clients who used our software years ago and still haven't upgraded. I may work a day a month if that, so I guess I am as close to retirement as being retired.

Anyway, I totally understand what you are saying. That's why when people on the Wrangler Forum (I have two of those also) talk about the 6.4 Hemi, it sounds great but something that gets 12-13 MPG on a good day? Not for me. The 3.6, with all its faults, sounds sweeter to me, especially for 20-30k less.

It seems to me that Stallantis should just get the 3.0 diesel back here. I have never personally been a fan of diesels since I tend to keep my vehicles a long time and know that working on a diesel costs more than a more traditional gas engine. But a lot of people like them and I would consider one if they had the same towing (7,000 lbs) or more as my 3.6 JTR.

But that's just me.

With the Mojave I have only been able to get to 16 MPG on the screen twice both times with about half the trip off road in Sand and Rocks the other half two lane highway maybe they messed up on predicting what i would modify and how i would use it. I never kept track of MPG on previous jeeps just made sure to get them with the biggest fuel tanks i could and not worry about it.

Not all Jeeps get bad mileage.

Did you fill the Jeep up at a station on the top of a high hill and then take the reading at the bottom?

68 miles of miserable Interstate road construction on the way to a ride.

I reset it the other day at the start of a 200 mile trip, mostly highway but with some mountain roads in the middle, averaged 19.2 mph. Local roads around home it's usually 18 something. That's a Sport with 33" Mojave takeoffs, doing 70-80 on the highway.

My old CJ5 was a lot worse, maybe 11-13, and 55mph was about its limit.
