Default E10 (ethanol/ gas) and 2-cycle engines

You can take the un-gasoline, pour it into a transparent container,
and add water. Let it sit. The water & alcohol will bond, and sink
to the bottom. Carefully suck off the gas on top.

================================================== ===========

If you do that, your gasoline will already be water-saturated (gasoline will
hold around 0.15 teaspoon of water per gallon at 70 deg F; E10 will hold
about 3 - 4 teaspoons, but you will lose the alcohol with your trick).

So what you will have is gasoline that is ready to drop its water with the
slightest drop in temperature. Other compounds will precipitate out with the
water, and those are highly corrosive.

If you expose dry gasoline to air, it takes at least three months for it to
become water-saturated; E10 takes much longer. So you won't encounter this
problem unless you intentionally mix water with your gas or E10. Neither one
is going to produce a happy result.
