I found this very interesting, and noticed there are a few guides online for doing this as well.



Problem is, I'm doubtful this would actually be useful. Sure if you add enough water to ethanol-gas, you will form a separate layer that is mostly water with ethanol, and draining this off would likely remove a good amount of ethanol from the gas. Problem is that since the ethanol also dissolves in gas, some will remain in the gas, and it will also dissolve water into the gas. This is basically the problem with old gas, water absorbs into the gas due to the presence of ethanol.


So, you can remove some ethanol, but will also add water into the gas. No disrespect intended to 40Deluxe, but I wouldn't do this.
