Not Ranked
I haven't had the pleasure of buying 100+ octane fuel so I really don't know much about it. I have a sneaky suspicion that many blends over 100+ octane have some kind of oxygenate like ethanol or some other alcohol. You might inquire about the components in the fuel. The octane of ethanol is 115+.
