Gasoline is basically a commodity which is only made by a limited number of producers. For example, the gas you buy at a Shell station may actually have been made by Chevron, or vice versa. The major refiners are always swapping product. The only exception years ago was Sunoco who added a different color to their gas but I really don't know if that is still the case as there are no Sunoco stations here anymore. While there may be exceptions, I doubt that there are many independents gasoline retailers that are actually operating a refinery.
