Two things:

A.) Did I understand you right? You gonna run 20k mile OCI on M1 0w20AFE?
B.) Where did all the Moly come from in the Castrol 0w20 sample?

A) No. I will wait until the end of the 2nd 10k OCI on M1 before sampling again.
B) It is "Castrol OE," not retail Castrol.

Does a Mazda 3 call for 91 octane?

Nope, but it eliminates the fuel dilution issues skyactiv engines have while improving my MPGs.
