PROCEED AT YOUR OWN RISK. But word on the street is that you can run 93octane 10% ethanol in non ethanol mode and maybe even see a little performance bump.
Ethanol is bad for storage and fuel systems that arn't built for it. It also has about 30% less energy per volume than regular petrol.
That's why it has a bad reputation in powersports.
But, the Axys is a bit rich stock. So the small ethanol content in e10 leans things out to a good point for power and the splash of ethanol provides a margin for detonation.
Ethanol has a high octane and more importantly is an over achiever when it comes to cooling the combustion process to a point where detonation becomes less likely. It acts higher octane than its rating would suggest. Turbo applications, especially direct injection, are an awesome example of this. Guys tuning the latest generation Volkswagen Golf and BMW turbo cars are getting near race gas power results with blends as low as e-30. Its almost magical. Guys setting up to run e85, even in n/a applications are seeing wild numbers. Something that started out as a corn lobby emissions boondoggle has turned into a tuners playground. Talk about unintended consequences!
