    I thought this was a scolding but it turned out to be pretty interesting :)

    Theoretically no difference in pings going by octane rating alone, a quick google search shows E85 is at least 100 octane.

    My understanding about ethanol is that the ethanol itself has a very octane rating but im not sure what the octane is in e85. I think that the 85 number is the percent of gas in the mixture not the octane rating. Ofcourse certain fuel lines cannot handle the ethanol, thats the main issue.
