Reason why Castrol 0W30 (and other 0W oils in ACEA A3 and C3) category don't have LL01 is update BMW did to its specifications in 2018. New engine test is introduced specifically aiming at timing chain issue on N20 engines and more stringent oxidation requirements to increase OCI.
Oxidation is irrelevant unless you are pushing OCI to 15-20k or run race oil but than LL01 is irrelevant anyway.
You don't have N20 engine.
Bcs. of oxidation requirements oils that have esters or PAO and less Group III hydrocracked base oils that serve to control oxidation, they can't be approved for LL01 or LL04.
As for Pennzoil, always Castrol 0W30/40 over Pennzoil. Pennzoil has seriously low Zinc now to meet new API SP requirements. SP in 5W40 now limits Zinc to 800ppm. Reason for that is that numerous manufacturers have timing chain issues and a lot of Zinc is not good.
But, Zinc is best additive to prevent wear in rest of the engine. It is non issue if timing chain is done correctly and on N/S55 it is done properly.

Very interesting, I have been running PP Euro 5w40 in my 2001 525i as I thought it was one of the best oils out there from my readings but sounds like at least in some ways Castrol Edge may be the better bet.
