Here is a list a dug up online. Next question, at fuel depots were individual vendor additives are added to bulk refined fuel ... are the formulas and concentrations standardized. In other words can Chevron have one contractor fuel depot adding XX ounces and another depot adds YY ounces. What I am trying to pin is industry standardization (like coca-cola). I know at the old valero refinery my dad work, they would sell the fuel to other chains, but each chain had a separate additive tank. Only Sunoco had thier own refinery for thier branded stations I can remember.
