There are indeed other oils that meet this spec but the Castrol at the dealer is the easiest to find.
100% on every point.
Yup
Dealer oil is also among the cheapest...
NAPA may have Liqui Moly (Top Tec 6200 I believe), they can get it if they don't have it...
The M1 meeting spec is allegedly available from Porsche dealers

People will argue this vehemently both ways... IMO why not is because it is not necessary. In case you're wondering if I will put my money where my mouth is check out the UOA section.
