At every pump I have seen they do have disclaimers that say something like: "may contain up to 10% ethanol"

Rarely have I seen the disclaimer on premium/super (92-95), just the regular and plus (85-90).

Racing gas (~104 octane) is great for modified turbocharged engines, but won't help a modern stock computer controlled car at all.

I regularly use 87 octane on my current supercharged car and the knock sensors retard boost so it makes less power, but it does just fine otherwise. When I want to flog it, I'll run higher octane.
