No it's not, gasoline has far more BTU's than ethanol & thus more power. Octane rating is a rating of resistance to ignition not power potential.

I am not aware of any fuel in Wisconsin or Illinois that is ethanol free and 92 octane. Unless you are taking about a marina, race track or airport.

I made no statments about BTUs or power. So, I don't know why your making this response to my answer. What is your recommendation to tlzkaasen? And what do you dispute in my answer? Have you ever purchased fuel in Wisconsin or rural Illinois and understand the situation?
