Why is there a non ethanol mode to select? to me that tells me the sleds parameters are set for a gasoline with potentially less octane since ethanol increases octane. so you should have no issues running it in that mode and with fresh ethanol fuel since it’s potentially a higher octane fuel being used reducing possible engine knock, but any modern engine will detect knock and take away timing to compensate for possible crappy gas.    interesting to hear from anyone with greater knowledge on the poos (@Nunz ) and the rationale used for this setting/design. 

That's why better than I could find last year.
