4.7qt.'s that is the first I seen that amount as the required oil amount.
It is incorrect. Just use some whiteout.
It's 5.0qt. And 6.0qt. Won't hurt it.
Let the carnage begin.
Possibly a rounding error made by the person who made the sticker accustomed to using metric, not freedom units.

Or possibly they used Imperial quarts instead of US quarts.

4.7 is accurate. If I put in exactly 5 quarts, mine is up onto the cable, above the full mark. 4.7 is more a military thing. 5 is for less particular or able consumers

That really seems odd it is the first place I ever seen it at 4.7qts. Ever. I owned one of these since 2020.

5 for me hits at the perfect full mark. Nothing on the cable. Odd.

That's either a carry-over from the other Jeeps using these engines (such as the Grand Cherokee) or a dry capacity. On some engines I've built over the years, I found when starting out with an engine that is 100% dry, then adding oil, it ends up a tad below the full mark. But do a change, and it takes the 5 quarts.
If you have cooler lines and so on, there's capacity in those that just doesn't show up in a change.
So I wonder if some of the numbers are dry capacity, brand new, no oil in anything at all measures.
I bet if I dug deep enough into my books, I'd find similar discrepancies over the years, likely due to 'brand new engine" vs. "used engine, doing oil change" or similar factors.

Besides, are you going to tell a customer to measure out 4.7 or 5.7 quarts, or simply say "5" or "6" and call it good?

OTOH, we know how grossly inaccurate Jeep is on things.

Data plate should be 4.7 Liters since that is 5 Quarts.
For oil I use 5 quarts of Pennzoil Ultra Platinum 5W-30.

That's the accurate number - here's a bit from a tech site talking of these engines in the Grand Cherokee - note a key word -

Approximately. In other words, more like 5.7 but that confuses consumers, so just call it 6.

And this from an FCA technical document talking oil capacities - so, when do you check? Half hour after stopping? 1 hour, or overnight like me?
Note the key sentence - "the Pentastar Upgrade engine has a slower oil drain back rate".
Hmmm, so if you change the oil, and start it and check it even within 30 minutes, it may explain why 5 puts mine above but not yours

But we know Jeep isn't great at accurate specs, accurate web sites, and screws things up badly anyway.
Heck, they can't even create a working web site or give accurate towing information half the time.

Well, I think you already know I run a little extra in mine because I am always in such steep places . It's my OCD.
