Not sure about other parts of the country but here in Houston that is the way I would say 90% of the fuel is mixed. All gas is "regular" unless you add the percentage of X to make it "Super". They all self mix in the trucks. My dad would tell me that you would see every brand of truck from Shell to Valero to Texaco lined up at the gas racks. Unless it is a corporate station all the gas comes from the same place. You can usually tell the corporate stations because it will be .30 higher. Just because you go to a chevron and think you are getting your "Techron" it is the same gas, from the same truck, that just left the shell station down the street. That is just the way it is.
