It has the 3.6 pentastar, which has been in every jeep since 2012.
So with that, expect 15 mpg average.
My common issues? Use mopar brake pads and rotors. Replace your spark plugs @50,000 miles. Change oil and filter @3,000 miles...so every 3 weeks. Air filter often. The oil lid filter cap has a specific torque, overtorque and you'll break the filter housing. Transmission/differential flush @40,000 miles. Avoid removing the pan. The tick will develop eventually, pretty easy to replace rockers/lifters. And finally, spray undercoating oil on EVERYTHING underneath every fall.

So 30 years and they have basically gotten worse? I have 406k on my 95 cherokee. I get an average of 14 mpg on my 120 mile route with 211 customers. At 5 k mile oil changes I'm about a quart low every time. I use cheap rotella. 50k transmission fluid changes; I'm sure dex 3 is cheaper than +4 or whatever synthetic fluid is required on new ones. I run double platinum plugs and get 100k with them. Brass cap and rotor still look good after 120k miles. I'll keep my old beater over that new junk.

Have a 2023 2.0 liter turbo Wrangler. It gets 18 mpg on my route. It's not a bad vehicle so far. Had one problem where it threw off the serpentine belt and was at the dealer for 60 days. It was a bad alternator pulley and they couldn't get the part anywhere in the US. Filed for breach of warranty and settled with Jeep.
Route is 70 miles.

What is with that oil filter housing design? Filter on top as well. Silly design. Has more power than my 3.8l mail jeep though. Otherwise, had it over 10 years, no problems yet...
We still have the family '77 cj-7 on the main farm. Doesn't have a ton of miles since it is a bad weather mucker. Wiring has been replaced 3 times now and engine rebuilt after a bad flood year. It lives in the machine shed so the body is good. I think it gets around 14 mpg, too.
But, that design is much simpler than new rigs. No multiple harnesses on the beast.

That's what I did.
And the OP can get whatever you want. I'd suggest with that route, get it new. Buy the manufacturer specific maintenance plan AND the manufacturer's COMMERCIAL warranty. Everybody has these warranties, ford, honda, toyota, jeep, ect.
Example: if you have a Ford dealer nearby. Get the van. Buy Fords maintenance plan that covers all wear parts/oil changes up to 150,000 miles. Buy Fords commercial warranty up to 150,000 miles. Have the van converted to rhd by a place like strutek. And for the love of god, get the usps contract via mou8 before you buy anything!

Jeeps factory warranty and extended warranty covers commercial use. Dealers will typically try and sell you a 3rd party warranty which does not. Went round and round with the dealer and finally got it in writing from Jeep corporate.
