At the normal auto parts stores, Castrol 0w-30 is the on Castrol Syntec (Edge)product that meets BMW LL-01. Castrol syntec(Edge) 5w-30 does not. Read the back of the bottle. BMW 5w-30 is made by Castrol, but is rebranded European spec oil and is not the same as normal Castrol Syntec 5w-30, does not meet HT/HS >3.5 for instance.
Mobil 1 0w-40 also meets BMW LL-01.
Of the readily available, easy to find over the counter products choices are
BMW 5w-30 (Dealer)
Castrol 0w-40 (Autozone/Pepboys only)
Mobil 1 0w-40
I choose Mobil 1 0w-40 because it is easiest to locate, Probably the best most up to date oil anyway and can find it for around $6.50/Qt on sale or at Wally world.
There are other choices but much harder to find, Motul, Elf, Lubromoly,PU etc.
That's the down and dirty, careful with all of the "advice" and good luck.
