Phase Separation = Water + E10 Bell Performance

Phase Separation = Water + E10. If you were to see a cut away view of that tank, you see the gasoline on top, a milky layer of ethanol+water below that, and a small layer of just water at the very bottom. That gasoline is probably a lower octane fuel than it used to be, because the ethanol strips out some of the octane and takes it away when it falls out of solution.
