ExxonMobil clearly states which product has the specification, there are some that do not actually carry the spec but wish you to believe they do.
That is actually mostly correct. Most of the time, mfgrs say "meets or exceeds Chrysler MS 6394."
The only guarantees on this list are mostly all the Sopus choices and the Mopar choice (obviously)
Rotella Gas Truck does intrigue me. How does a less than year old product meet the two year test period (which I believe is tested in Vegas Taxis?)
I would probably say Castrol is telling the truth, as Edge EP and Edge are both good and cite the spec, yet Ultraclean GTX and Magnatec 5w20 have no mentioning of meeting it. BP more than likely only paid for the two Edges to be tested for some reason.
There are also some brands, such as Valvoline, that "meet the spec" but their sister oils (NAPA) apparently do not. Same goes with Warren Distributions Mag1 meeting it, but Accel and their private labels do not mention it.
Anyways use the list, go to the brands websites, use their TDS or look on the bottles, this is usually what I've seen that mentions anything Chrysler on the sites or bottle.
Hopefully that list will kill the questions of what oil to use for this spec for future posters.
If you look at Napa site put in a different year and you will see it meets requirements for Chrysler Spec. I did talk to Valvoline which I put email on this site where they stated Napa meets requirements and Valvoline exceeded them.
I find it very, very, idk misleading, when a company says something meets something but doesn't print it.
Like putting it on the bottle is what, 1/2 inch of print? It's pretty shady. I'd rather see on the bottle that it's what they say it is.

If approved it is on bottle but meets requirements it is not. In other words one is tested and one is copied.
