I disagree. If they mixed the same 92 octane gas that we used to get with ethanol, then yes it would bump up the octane level. Notice it still says 92 octane though? Well, they are taking the old 90 octane, mixing it with 10% ethanol and you have 92 octane. So we aren't getting any gains from it, we use more fuel because of less energy stored in the ethanol.
