I just ordered the 5W-40 Euro-spec oil, the Mopar anti-freeze, a new drain plug, and the Dorman aluminum oil filter housing with oil cooler. Might as well swap out the plastic unit while I have it torn down.

I would definitely step up on the oil changes and not go as long as, well, don't run the miles up like I do. I have more controlled conditions, less loading, and less heat and so on. I'm not afraid to follow the oil life monitor.
I'd cut it like they suggest as you'll not only have more loading but likely more fuel contamination as well. If it was mine, depending on how I was driving, the weather and so on, I might push 4,000, but otherwise, the 3500 miles would probably be my personal norm. But you'll know how you drive it, how long you drive it and under what conditions.
Ethanol runs a lot cooler, less carbon build-up and resists detonation under pressure - not sure what they say about gas with ethanol.......... would be interested in their comments on gas with ethanol and their product.

Retired. Beach bum.
Mine is still very close to the full mark between changes. I've never needed to add anything. I'd say they've never even been a pint low.

A pint is nothing - why bother with that?
I'm not sure why you would bother changing until a change was needed or it was a quart low.
Yeah, I’m right there.

Wanna hear something funny/crazy? My buddy weighed his JLU right after me and he was at 7400 lbs. No trailer 😵💫
He’s on 40’s but damn
I really hope he has serious brake upgrades to help slow/stop all that extra heft.

I question that on a JLU - that's over 1,000 pounds more than a very heavy JLU 4xe with all of that battery weight in there.
the Rubicon 4xe curb weight is just over 5200 pounds - meaning it's one of the heavier JLUs made.
Figure steel bumpers, winch, etc. - you might add a couple hundred pounds. I can't see how you'd get a JLU - even a very heavy 4xe - much over 6,000 pounds, let alone touching another HALF TON over that! Naw, I have to question that weight. It's way over GVWR for one thing, and it's saying he's added OVER 1 ton of stuff to a JLU

While a SC sounds great , I am just done with throwing money into this thing. There are days if someone gave me a good offer, I would sign the pink and be done with it.

Copy that

I change the oil often. Only once has it gone beyond 3,000 because I drove it over 4,000 on a single trip out west to wheel. It got changed when I got home.
The oil life is currently 95%, and it will be dumped, so I can put in the new recommended Euro-spec oil before starting it up with the new SC.

I addressed that. I installed Mo-betterer brakes than stock. It's documented in my build thread, and they work really well!

OK, OK, hold on-
Just take a couple of deep breaths
Concentrate on your breathing and relax
You're having a reasoning attack
Give it a little time and it will pass! ;-)

Was checking out after supper at Cracker Barrel and saw this. Immediately thought of you. 😊

Not for the larger V8
Even the optimistic numbers on a JLU window sticker aren't much better than that.
EPA says 14 combined, reality in the forums and elsewhere suggests 12 mpg for a 392 V8

We talked about the V8 with our sales guy when talking a JLU for my wife. Even he suggested she'd not be happy with the mpg and few actually get the sticker numbers. He could have upsold.

The Jeep Wrangler Rubicon 392 gets an EPA-estimated 13 MPG city, 17 MPG highway, and 14 MPG combined, thanks to its powerful 6.4L V8 HEMI engine, though real-world mileage often falls lower, sometimes into the low teens, especially with aggressive driving or larger off-road tires. Drivers report that enjoying the V8's sound and performance often results in figures closer to 10-12 MPG in mixed conditions.
Adding 37s+ tires and it'll be even lower mpg.

Even at 65-70 with 3.5" of lift and 37s it's 14mpg at best. I realize my speed doesn't help, but out here you get pased by semis if you're under 75mph and in AZ half of them are rolling 80+. The lift and tires don't help either. I still argue that more adequate power for my harder than most use wouldn't hurt mpg at all and on roadtrips it would likely help. If that power comes from boost or a v8 swap, either way it's going to downshift less and therefore run lower average rpms in my experience. Obviously when I'm out playing with all of that extra 150 wheel hp the mileage will be crap... but it's already crap if I'm using all 215 wheel hp and spinning the 3.6L up to 6k rpm.
I just let em pass piss on it
