Thank you
You need LL01 specification. There are multiple grades that fit LL01 specification as emphasis is on HTHS not grade: 0W30, 5W30, 0W40 or 5W40.
In Wal Mart you can find Castrol 0W40. It is stout, good oil. In N63 you do not want too thin oil because that engine's issue with vale stems etc. Now in 2013 it suppose to be N63TU version where A LOT of issues that N63 had were addressed. Still, considering turbos are in V bay, and ridiculous operating temperature, heavier grade would be best.
In Wal Mart you have several options:
Castrol Edge 0W40 is probably best option
Mobil1 0W40 FS is good, but seems watered down compared to pre-2015 (does not have LL01, but that is OK< BMW is phasing out that specification).
Castrol Edge 5W40 is available, but avoid it.
In the end, always look that il has MB 229.5 specification if not LL01 or together with LL01. Reason is that MB229.5 is more stringent.
As for Redline, Redline is murky story. They have their Ester based oils, but not approved. Their approved oils, Professional series is mediocre at best.
Amsoil has approved oil, but not enough information how they performed in these engines.
