why not leave the water in there? Way back when I first got my metro one of the first experiments was water injection. with 10% water to gas ratio I got 10% better mileage. Water really wont hurt the internal engine parts but I have no idea about the long term problems in the fuel system.

My setup was some fish tank hose and a bottle under the hood putting water into a vacuum line on the throttle body. I never could keep it dialed in at 10% less water more or less proportionally got less increase in mileage but more than 10% didn't really do anything at all. Even going to something like 20% didn't change anything.

I looked before for ways of adding water to gas and keeping it in suspension. If this works and can keep the water in suspension long term, then it could be even better than straight E0 gas. It would have lower than 87 octane so you get more power out of the fuel but the water keeps the engine from knocking and helping the pumping losses.
