You should look up Dunning Kruger. The less you know, the smarter you think you are.Yeah you aren't going to convince me. You believe what you want and so will I. I'm not trying to change anyone's minds.
There's many threads on here that cover it, even from a guy that delivers gas. Basically all gas in a particular area comes from the same terminals. Wouldn't make sense for there to be several different terminals in the same area. We get deliveries around here from tankers that have 10+ million gallons. You think each gas station brand is going to have their own 10+ million tanker delivering gas to their stations? It's basically all gas from the same terminal. The only difference is the additive package so each gas station gets their own additive package depending on the brand. But it's the same gas from the same terminal. Costco seems to do their own thing where they have their own additive package on site instead of being blended at the terminal.
