It passes the engine test portion of the license requirements but not the bench test. It's largely irrelevant especially in light of that fact that an API license is also largely irrelevant for this product.

It also requires certain % of Group III.
What is the reasoning behind requiring a certain amount of a certain base oil?

Could be gaskets and oxidation. If it has high amounts of Group III, BMW gaskets never leak
So I'm guessing the ESP 5w30 is a pao/group III blend primarily targeted at the BMW spec?Could be gaskets and oxidation. If it has high amounts of Group III, BMW gaskets never leak

Not sure. I think it is just that Exxon/Mobil figured out how to get similar results using cheaper stuff.
Where can you find the actual requirements for the Longlife approvals?
I would like to note I do not intentionally mean to post any information that is incorrect. If I see something that makes sense to me I'm inclined to share the information. My comment on the potential lack of ester in correlation with BMW LL 04 was that I understood that BMW has a strict cap on oxidation, and an oil with even a small amount of ester Co base is going to have a higher than allowed virgin oxidation value. If that is incorrect either partially or completely I certainly welcome clarification.
My comment regarding the revision code comes from an understanding that Mobil uses a four digit code, printed on the back of the jug, that is assigned to a particular formula of a given product, and if that code remains in unchanged then so is the formula. Same applies to this as to the above. I'd like to be helpful. Not trying to further confuse anything or intentionally telling people the wrong thing

Motul has that specific language in their pds. I don't have access for current 2022 update.
I must be using the wrong base oil from the begining then. good to knowCould be gaskets and oxidation. If it has high amounts of Group III, BMW gaskets never leak
So they take away is regardless of label I’m safe to use ESP 0w30 in a Honda L15BA for a 6-8000km OCI
Phosphorus is an anti-wear and antioxidant additive. It’s a component of ZDDP and works in conjunction with Zinc.
Yes use with confidence.
Is high amount bad for Catalytic converter?
Only if it gets there.
If burned in very high quantities yes.
I’m talking more than a quart per 1,000 miles quantities.
Isnt one of the ESP advertisements that it “protects emission system”. Ive never seen other oils advertising emission system protection. Interesting
Many ACEA C oils do advertise that, for example Shell calls it ECT. Particularly important for diesel or new gas vehicles and their particulate filter
