I remember seeing a Modern Marvels on gasoline and they repeated that several times ,,, and all 93 oct gasoline is the same, so is all the 87 oct,, the additive is added just the gas in put into the tanker trucks ,there are usually 3 different sections on each truck,one for 93 one for 89 and one for 87 . jim
