Is there a good way to scrub ethanol from the gasoline for use in our garden equipment? I was thinking of buying pure gas from a marina next time I'm near one, but people tell me it cost $6/gal.
Is it as simple as adding a good amount of water, shake, let settle, and decant the gasoline? Has anyone tried it?
I ran "washed" gas all spring and summer for my lawnmower which uses a 4cyl Honda GCV-160. Ran perfectly fine, noticeably improved power and fuel efficiency from E10. I can cut a full 1/3 additional lawn surface area with the washed gas.
Use a "no spill" gas can that has the push button dispenser (the one where you can set it so the opening is on the bottom, parallel to the ground so that the water/ethanol mixture is the 1st thing that comes out because it's heavier).
I would get 4 gallons of 93 E10 (so that I would still have at least 89 octane after removing the 112 octane alcohol which is fine for a 4 stroke) then add one gallon of water. Shake well for 5 minutes continuously (somewhat of a workout). Then let it sit 30 mins, drain off the 1 gallon of water you added (an empty distilled gallon water jug works fine) plus the 51+ ounces of ethanol.
Rinse and repeat a second time to get any residual ethanol out. Then use an F15C Mr. Funnel fuel filter and filter the entire remaining contents through into another clean & dry 5 gallon container--this will catch any minute amount of free water.
I'd want to dry that gas before burning it.
After I do all of the above I add 1 ounce of seafoam. If you still weren't comfortable with that you could add a small amount of iso-heet red bottle. A lot of people have often used seafoam anyways so they wouldn't be changing anything additive wise.
I guarantee that if anyone tries this that whatever you run it in will run noticeably better than on E10.
Even before any isopropyl is added, there is zero water visible at the bottom of the remaining gas that was just filtered. I confirmed this by dispensing it in a clear container and inspecting it.
