Here is some more info based on your 10 minute commute.
IF your oil gets to 70C/158F during your 10 minute commute (might, might not with 6.9 quarts)
With Amsoil oils your oil viscosity at 70C / 158 F would be:
0w-20 17.6 cSt (equal to a 50 weight motor oil@212F)
0w-30 21.5 cSt (equal to a 50 weight motor oil@212F)
0w-40 31.1 cSt (equal to a 70 weight motor oil@212F) 60 weight stops at 26.1
Even with the turbo in a 10 minute commute I doubt your oil would get to the HTHS temp of 150 C / 302 F.
I would suggest changing your oil at half the BMW OCI because of all the short trips.
I would also suggest you get a Battery Tender 4 or 5 amp charger and connect it at least overnight every two weeks (maybe even weekly) as the short trips will not fully charge your battery on a consistent basis.
