AGAIN: If the oil carries LL01 approval there are no significant differences in thickness between grades; whether it says 0W-30, 5W-30, 0W-40, 5W-40, Castrol, Mobil, Motul, Mag1, or Ravenöl on the bottle is irrelevant.
If an oil is LL01 APPROVED, just pick the cheapest one, or whichever brand you prefer, or whichever bottle looks the coolest. It's splitting hairs trying to find an actual reason pick one over the other.
