Ask the service manager at you dealer what they fill the cars with for a oil service.
Should be either 0W-20 or 5W-30 in the USA.

USA is supposed to be moving from the 5W-30 to the 0W-20 for fuel consumption and emissions reasons, but im not sure how far they have gotten with the rollout.

0W-20 is only approved on the new engines (B48,B58) and only in certain worldwide markets.


The worldwide approved oil is the BMW 5W-30 one.
If the factory fill all engines with the same oil it would be this one (5W-30)
If they fill specific oil for the US it may be the 0W-20 one on newer cars. older F48 X1 would have been 5W-30.


For topup either should be fine.
These engines shouldn't really use any oil between services
