From what I've read, the core fuel is the same, it's the additives added that differ.
And as we pretty much know, the super fuels just have even more additives. (Cleaning power, cetane etc)

It seems to me that we assume, infer, claim, guess, hope, etc., but nobody here (or on every other car forum where these same debates rage) actually knows! It would be great to see a table showing the specific ingredients of the fuels sold.
And can every petrol car make use of an increased octane rating? Does every car need the alleged 'cleaning' additives?
Fuel is energy, but additives obviously displace fuel; so why aren't we worried about this?
