I have a question and I know it's been talked about a million times. I'm about to do my own oil change and was wondering should I use Mobil 1 5w-30 or 0w-40? I don't track my car but it is a daily driver.

If you are going to use mobile use the 0w-40, but for that price might as well play it safe and buy the dealership stuff. Its made by castrol and its good stuff for the most part. I think mobile1 is over rated. I been a bigger fan of Castrol for all my cars over the years.

You need oil with BMW LL01 approval. In the real world that means:

The BMW oil from the dealer.
Castrol Syntec 0W-30 (NOT the 5W-30)
Mobil 1 0W-40 (NOT the 5W-30)

Do not buy any oil outside of the dealership that does not say "BMW LL01" in small letters on the back.

This means none the 5W-30 oils commonly sold in the United States. Not Amsoil. Not Royal Purple.

Of course it is your car, but I am assuming that you want to keep your warranty intact. And speaking of which, keep the receipts.

So, its safe to buy 0W-30 Castrol or 0W-40 Mobil 1 from the local auto store?

Of course, as it is the only place you will find it (other than online, and say Walmart).

You can also buy Valvoline HST 5w-40 which is also LL01 approved.
