For oil filters in dumb places like that, I use heavy duty aluminum foil and build a little slide to drain the oil into. You can always mold the shape to work around any obstruction and keep everything clean.

You are right. Once lifted it will have more clearance….

Have you tried Castrol edge full syn? Our 07 Rubicon liked it better than mobile 1, royal purple or valvoline (full syn)
I remember when non syn pennzoil left the most sludge . What are you using currently?
Have been using Castrol edge 0w20 for my 2018 3.6 since new and been fine. Always available on Amazon and cheap. Currently using Pennzoil Ultra Platinum Full Synthetic 0W-40. It’s recommended by srt and listed on owner’s manual as well.

The dealership changed the oil at 2200 miles. (This week) They put in that Pennzoil. Now the engine makes a slightly different sound. (Sounds like a belt squeak) I've just ordered Castrol and as soon as I get it I am going to change it. Just don't care for Pennzoil. But I love that 392!

Maybe this is a dumb question.. I've never seen the underside of the 392. Is that some cast aluminum part/sump hanging down like that?

If you mean the silver box where the oil is draining below, that's the bottom of the oil pan (it hangs fairly low).
Wow, and it's aluminum? Someone needs to design a skidplate for that.. and quick!

cast aluminum or stamp sheet metal wasn’t the problem. Hanging super low and have a huge even lower drain plug is the problem.

I had my first oil change from my dealer at 2,000, had them put in full syn, Pennzoil, every 3,500 after that, have the v6.
I did my axels at 10,000, the rear was black and dirty, front was lite brown.

He's better off not doing that. That drain plug alone is just aching to be hit and ruin that cast aluminum oil pan. The oil he mentioned getting on stuff isn't from draining the oil, it's from the oil filter removal since it holds quite a bit of oil. I would use a punch or something similar to put a small 1/4 inch hole in the bottom of the filter and use a funnel to direct that into a drain pan if needed. That's how the pros do canister oil filters on some semi trucks and other heavy equipment.

What’s the best way to puncture the filter?

I've used long punches or even a screwdriver. Use a hammer to hammer it through the metal of the filter just enough to get the oil to drain out of it. I've not done this on the Jeep 392 so I can't say best location to put the hole.

There are a few companies who make low profile oil pans with drain plugs on the side for the 6.4l. Probably something I will end up getting at some point.
