The gains were made because of the oxygenated fuel, not because of the octane difference. Oxygenated fuels have a lower power stoichiometric and thus you have to run a richer AFR mixture then non oxygenated fuels to compensate. While oxygenated fuels will reduce gas mileage they are able to produce more energy during the combustion process.
