Wendell Noble [ November 2015 ]
Dave was super busy this month so the staff at Wheel Tracks decided to go with a story that Wendell Nobel mentioned about making non-ethanol gas out of ethanol gas (E10).
The hope is that members will
not try the process but instead will more thoroughly
understand this ethanol problem that we have.
Wendell Noble tells a story of an article he read of someone in the Northeast Kingdom removing ethanol from his gas for his chainsaw use. The gent simply adds water to five gallons of the dreaded E10 gas. The water speeds the separation of the ethanol and settles to the bottom of the gas can. The gent then siphoned off the non-ethanol gas on the top. He uses the “stuff” on the bottom, the water and ethanol mix, to wash his windows! (who wodda guessed). Here is a more detailed process taken from an internet story…...
How to make your own ethanol-free gasoline…...Ethanol is the scourge of owners of old cars, motorcycles, boats, and many other gasoline-operated vehicles and implements. E10 (10% ethanol) is pretty much the only available gasoline in most of the country now, with a few stations offering ethanol-free gas. And E15 (15% ethanol) is coming soon, recently approved by the EPA for 2001 and newer cars - even though the car manufacturers don't want it. You can thank the ethanol lobby for that.
What's the problem with ethanol? The biggest problem is phase separation. Like brake fluid, ethanol is hygroscopic, which means it bonds very easily to water. If there is moisture in the air (which there always is), the moisture bonds with the ethanol. The combination of water and ethanol is heavier than gasoline, so it falls to the bottom of the gas tank, where the pickup is. Let it sit for any length of time, particularly with a partially-full gas tank (because the air space left will contain moisture, and will expand and contract with heat, sucking in more moisture-laden air), and your tank will have a layer of water/ethanol mixture on the bottom. This is called phase separation. Guess what gets sucked into your engine the next time you start it? The water/ethanol mixture will burn in your engine, but it will burn much leaner and hotter, with the potential for serious engine damage as a result. Ethanol is particularly corrosive to plastics, rubber, aluminum and fiberglass when compared to straight gasoline.
So what is the solution? Well, you can check out the web site http://pure-gas.org to try to find a gas station near you that sells ethanol-free gas. Hint: many boat marinas sell ethanol-free gas, because with the added moisture in a boating environment, E10 plays havoc with boat engines. How do you remove the ethanol from E10? It's quite simple, actually - just add water! Remember, ethanol bonds strongly to water. All you need to do is add some water to the gasoline, agitate to make sure it mixes well, then let it sit for a few minutes. The water will bond with the ethanol, and it will phase-separate out, falling to the bottom of the container. So how much water do you add? It depends on a few things, including the actual concentration of ethanol (which will vary - it's seldom exactly 10%), and ambient temperature. Dave's testing shows that the optimal amount of water is 2% by volume of the E10. That's 2.56 oz per gallon, or 12.8 ounces for a five-gallon gas can. Remember that extra water will simply separate out, so two cups (16 ounces) of water in a five-gallon gas can is safe. You should use distilled water only, to avoid leaving behind any minerals or other additives that your engine may not like (does fluoride keep your carburetors clean?).
Please folks, Wheel Tracks suggests that you do not try this procedure.
Isn’t it amazing the lengths folks have gone to operate their gas engines without E10?
One wonders if you line up twenty politicians in a row
and ask why we have ethanol in our gas,
what ridiculous answers we would hear.
