Do "off brand" gas stations even exist anymore? In my neck of the woods,
pretty much all stations around here are with one chain or another, whether
it be Shell, Valero, Conoco, Kum n Go, Casey's, Murphy's, Wal-Mart... And
gas delivery trucks might stop at a Valero, then go top off the Kum N Go
down the street!
The gas might be all the same, but the additives are different, dispensed by the truck as it delivers to the underground tank at the station.
The Speedway station might get 100ppm of Marathon's detergent, and Marathon might get 200ppm, while the Shell station gets 150ppm of something entirely different.
