Combustion Catalysts, Oxygenators, Antioxidants, Antiknock agents, Detergents, etc.
They don't add power per se, but they do allow your engine to run cleaner and more efficient, with less deposits (gunk). Over the long run, your engine runs better and lasts longer, with perhaps a small amount of performance gain due to a lack of crud inside.

I know shell advertises nitrogen or something in their gas... Its all a marketing scheme.
I remember a friend i had in high school who swore he got better fuel mileage from 89 octane over 87.... i tried explaining octane levels, compression, and ignition timing but he just didnt believe me...

I doubt it's just a marketing scheme. There may not be any appreciable mileage gains, but a clean engine is a happier engine. Perhaps purple mustangs don't care as much about the fuel they drink?
