i have used Castrol exclusively in n54 (on previous cars aswell except 1 where i experimented with Liqui Moly). N54 OEM oil cap even has Castrol logo on it and i think Castrol has BMW recommendations aswell... i have used both Edge 0W40 and Edge 5W30 in my car. No noticeable difference. Some say 0w40 oil gets burned off more easily... not sure of it but at the moment my car has 5W30 in it...
I drive 4000 miles or so in a year so i just do an oil change once a year. In 2020 i actually changed oil after only 1800miles because 1 year had passed from the previous oil change.
