Is Costco 91 good for our 240?

Hi friends. With the crazy gas price now Costco gas is going to save a ton of money. Just wondering if the costco gas is good enough or as good as Shell v power for our b58 engines. There are discussion on this everywhere but it might be a more relevant question now!

I have used costco premium for many cars (including BMW and Porsche) over the past decade or so...no problems at all.

Yes, filling up with Costco 91 is fine for the B58.
