Please elaborate. Are you asserting that E85 delivers better fuel economy than unleaded regular?

Isn't racing gasoline a mixture of fuel?

[Mr. Lucky]

It delivers poorer economy, but increased performance.

That extra oxygen molecule it carries around with it adds no energy but increases its expansive power.

Methanol, which has even poorer mileage but more power than ethanol has historically been the fuel choice for race engines. Starting next year, the Indy Car circuit will switch from Methanol to Ethanol as a way to showcase its performance capabilities.
