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.
