Using a non-BMW oil is fine, however, it has to carry a BMW approval such as LL-01, LL-01FE, LL-04, LL-12FE, LL-17FE+, etc. If you go off label and use a non-BMW approved oil like the aforementioned Redline, you are at your own risk. Redline is a good oil but not sure if it's worth the risk they fight you under warranty.
The safest thing from a warranty perspective is to use the spec that your manual calls out. However, BMW's authoritative source is TIS which will likely list multiple options. The difference between all these specs is viscosity and ash-generating additive/detergent levels (SAPS). Since US spec cars don't have an additional exhaust particulate filter (GPF), you are safe to run full-SAPS spec oils which are LL-01 and LL-01FE. EU cars would have to run LL-04, 12, 17, or other mid-SAPS spec.
