I believe it's uses one of the local distributors in the area it's in. So could be Mobil, chevron, shell, etc but then they add detergents to it. I've never had an issue running Costco gas when I have filled up there though.
But it's definitely an "only if i'm already there for something else" type deal. Because like everyone's mentioned, whats the point of a dedicated trip to save like $5. In general, the once in a while i do go to Costco, I usually go at random midday times during a weekday. Lines at the gas are usually non existant and the warehouse is relatively empty
