All the companies fill up at the same refineries, it is the additives added that make the difference.
I have known that for a long time and that is what drove me crazy at first. I went through a whole bunch of expensive engine diagnostics and injector cleanings (auto shop types) and still had a rough running van until I used Chevron or Shell then it just plain smoothed out. I do not know how to explain it other than something in the additives that my van and car really like. My car feels like it runs OK on any kind of gas but the oil consumption is a quart per 1k miles whereas using Chevron/Shell is 1 quart per 3-4k miles. Again, I technically have no idea why, but it is what it is.

The same base gasoline is used at all the stations. The majors add their own unique additive that cleans injectors and the like.
