Well, if you don't blow yourself up in the process, you will now have low octane gas for about $4.50/gallon.  Then you'll need a method to transport it to the airport, then pump/pour it into your fuel tanks, again without blowing yourself up.  From a risk-analysis perspective, it doesn't wash (pun intended).  I just don't see the benefit here.  It would almost be easier to fly to Oklahoma whenever I needed fuel for the airplane.

    Thanks, Bill.  That chemistry class in college was a LONG time ago

    So, how long will it be before someone starts selling a system that

    water and then centrifugally separate it, let the clean gasoline go
