But agree I would lean toward the LL-01 FE 0w-30. In fact out of warranty, I would use the LL-01 5w-30 or 5w-40 which has a much higher HTHS (high temperature, high sheer) rating. The "FE" versions I believe, are optimized for fuel economy.

HTHS of LL17-FE is equal or greater than 2.6 Only available in 0w-20

LL-01 FE is equal or greater than 3.1 Only available in 0w-30

LL-01 is equal or greater than 3.5 Available in both 5w-30 and 5w-40 note that both oil viscosities will be similar, in order to meet the LL-01 rating. So that means the 30 rated oil will be at the higher end of 30 weight oils, while the 40 rated oil will often be on the thinner range and still be considered a 40 weight oil.

Note that higher viscosity range, usually (but not always) correlates to higher HTHS. But you only know for sure by reading the specification sheets for each individual oil. If it has the LL rating, you know it at least meets the minimum HTHS ratings above.

Since you seem to be on top of oil info, do you happen to know what the Amsoil euro 5w-40 or 5w-30 look like as an oil for the M550? I like boutique oils (kinda).

I personally would run in N63 XW40 oils.
As I stated before, changes in 2028 to BMW approvals really affect B generation engines and N20/26.
In N63 if oit of warranty, Castrol Edge 0W40!
If under warranty and allows LL01:
Motul X-Cess 5W40 GEN2.
Pennzoil Platinum Euro 5W40
Valvoline European Vehicle 5W40.

If LL01 FE:
BMW TPT 0W30
Motul Specific LL01 FE 5W30.

Exotic oils? Motul? Is it exotic enough? Try Ravenol!

Motul is pedestrian stuff. I expected some vegan, free range dinosaur based oil or maybe "impossible oil" when someone says "exotic"!
