For example z4 m40i B58 engine can be filled with 0w20 oil as well (LL17 FE).

If the 0w-20 is approved for your engine and you aren't tracking the car or doing autobahn runs, it might not even be a bad choice. I probably wouldn't run it in the S55 though.
I doubt there is a lot of difference in 0w-30s that meet BMW specs, all the good oils are all produced by similar processes and have similar additive packs unless you get into more exotic stuff.
