4xe? v6? turbo 4? 392? I think the turbo 4 and 392 need premium, 91 (no 92 in my area), but v6 and 4xe take regular.

In my experience, the 92 is better. The 3.6 is a high compression motor, yes you can run 87 but I believe it runs better on premium. I see a slight bump in mileage as well. A tune makes the most of it, but not available yet on newer Jeeps IIRC.

87 pure gas. owners manual states there is no performance increase with any higher octane 87...

I believe it runs better on premium.

It does not.

 

[BetOnBlack]

It does not.

It can. That just means there is a problem that the increased octane is hiding.
