    Default 10% Ethanol

    So i pulled into my favorite local gas station and they have new stickers on the pumps saying"may contain 10% ethanol".
    I am interested in what you mechanics have to say about that according to my manual Im supposed to be running at least 89 octane.
    Will the ethanol hurt anything or is 10% OK??

    I have 2700 miles on my bike I have only ever used Shell super in it. Ethanol is a fancy name for alcohol, alcohol is hard on rubber seals & gaskets, It won't have an immediate reaction but eventually will need to be addressed. If you do a search on putting E85 through your regular fuel lines it can give you an idea of what you are talking about ( E85 is 85% alcohol & 15% gasoline to keep people from drinking it, corn ethanol is the same chemical compound as grain alcohol AKA moonshine)

    Should be fine. Ethanol is an octane booster, but octane is octane, so if the pump says 93, it should be 93 whether it has ethanol or not.

    Personally I'm not a huge fan of Ethanol in fuel, but we've been using it for a while with no problems. (As long as you're putting it into a newer bike)

    I have a bigger issue with ethanol *policy* in this country, which is completely moronic and brain dead, a pure giveaway to the farm lobby.

    My next hot rod build is going to be a 1500HP car that runs E85 or E92 (depending on availability)

    It will be fine... but be sure to get the correct octane rating. You have probably been running it anyway, they probably just didn't have the sticker.

    Ethanol is like 110 or 114 octane... denatured alcohol.
    As far as the octane... the 87 starts it's life as 84, then they blend in the ethanol to get the 87 octane.
    For 89 they splash a little 91 in there to raise the 84 + E + a small blend of 91 to get the 89.
    Prem is 91 with the 10% E, making it the 93.

    I run denatured alcohol in a separate tank on my turbo regal when the boost gets to 5# it starts spraying the more boost the more alcohol gets sprayed, the next boosted car I build will get straight E85
