You guys haven't read many oil threads, have you? One of the top 5 subjects, perhaps one of the top 3.
1) BMW has always mentioned at least 4 other oils that meet BMW's LL-01 specification. In reality, any oil meeting the European ACEA A3/B3-4 standard is very close to LL-01 and would be acceptable. LL-01 is a bit more restrictive (viscosity, etc.), but what the heck.
2) SAE specs are garbage, and almost totally useless in choosing an oil for BMWs.
3) Amsoil says that their oil "meets or exceeds" BMW's standards. However, the same sentence actually says: "meets or exceeds BMW, Mercedes-Benz, Audi, VW, and other EU standards." Guess what, the oils that those manufacturers recommend and spec are all slightly different: there is NO WAY that Amsoil's Euro Formula actually meets all of them. In fact, it probably meets or exceeds the ACEA spec, not the manufacturer specs.
4) Amsoil has never paid an independent lab to confirm that their oil(s)
MEET the spec mentioned. They only
SAY it does, and there is no independent confirmation.
