Certifications are mostly a game. If a given formulation style has even one weight that meets a given certification, all weight will meet that cert even if they dont all carry the official badge.
To get an oil certified to a given standard oil companies must submit each and every weight of a given formulation (Euro, Max Power, etc) to be certified. For brands this amounts to millions in fees.
As such oil manufacturers and private label brands (like Mopar, who does not refine or manufacture oil. They put their own label on another manufacturer's oil, generally ExxonMobil) do not submit oil for new certification till there is adequate demand to justify the cost. OE brand like Mopar have an essentially captive consumer-base due to warrenty requirments as such they will generally be certified first as they can just pass the cost along to the consumer easier with less fear of losing them due to higher pricing.
0w30 weight oil, with the low viscosity and carbon requirments is not a high demand product. As such not many brands outside of "Mopar" have paid to have that specific weight certified to those specific standards.
However Penzoil Euro does have several weights that have been certified to the standards Mopar requires. This means the refinement process/ingredients/additives used to make the "Euro" line meets those standards, it just hasn't been certified to do so yet.
It ALSO means that since the Mopar oil is actually rebranded Mobil1..
Mobil1 also meets these standards even though it is not certified under it's own brand. Yet...probably will be in a few years, without reformulation. At least according to ExxonMobil on thier website.
Otherwise...if you are going to make a big deal about only buying oil certified to meet the Mopar requirments, the single most important requirment is probably the low temp viscocity.
That standard guarantees proper low temperature consistency of the oil..so the oil can fully and quickly circulate through the entier valvetrain at start-up. (The multiair valvetrain requires more lubrication then a normal variable valve setup, and has lots of very small passages that need low viscosity whem cold or the oil wont flow through them) Very, very important. Even more so then pre-ignition. Which is also important.
I have a case of Penzoil arriving Monday. 'Course I also have a 2018 that doesnt list the same certification requirments in the manual thankfully.
