My 2024 230i xDrive owners manual appears to allow both 0w-20 and 0w-30 oils.

A pic from the applicable page from the digital manual is attached.

If your owners manual has something similar then the factory sanctions either oil.

But I'll include this -- a paste from the owners manual:

Further information on suitable engine oil specifications and viscosity classes can be obtained from a Service Partner of the manufacturer or another qualified Service Partner or a specialist workshop.

The above just in case BMW has overruled what's in the owners manual.

As an aside I have had some experience with other brands of cars and the factory allowing for different multi-viscosity grades of oils.

For example I found Porsche allowed the use of besides the factory fill 0w-40 oil, a number of 5w-40 oils and even one 5w-50 oil.

There was a big warning to use 0w-40 oil in temperatures -17F (-25C) or colder. This was not a concern for me. My driving rather was in much warmer temperatures sometimes in triple digit temperatures. (See pic below.)
