Location: Rhinelander, Wisconsin | 'Ethanol is alcohol, and alcohol is “hygroscopic,” which means it attracts water molecules. Since nearly all boat fuel tanks are vented to the atmosphere, water can (and will) collect in your fuel. When the concentration of water molecules in your fuel tank reaches just ½ of 1%, the water molecules will bond with the alcohol and sink to the bottom, where your fuel pick up is. Depending on the amount of water ingested into your outboard, this can result in everything from running problems to catastrophic damage. Ethanol, being alcohol, is also a powerful solvent that can loosen debris in your fuel tank and all the tanks and lines it was in before it got to you. '
There is no way ethanol can phase separate in the fuel unless water is introduced through the system by leak or or evaporation, in which case you have a fuel system issue or are storing your ride in a very humid location for long periods of time. Additives do nothing to the ethanol in any way, they stabilize gasoline formulated to last a couple weeks before breaking down.
Additives that absorb water and a sold as 'fixing ethanol problems' are, in fact, alcohol also. Makes no sense at all...but most people do not think that through. Today's gasoline is formulated with several powerful and poisonous solvents, one that will actually dissolve rubber.
Ethanol at the e10 level would only present a problem if the fuel system is incredibly dirty and had never been run with ethanol. In that case, where did the deposits come from? How is that possible if ethanol free gasoline runs, stores, and ages without issues, and as advertised on the pumps, 'drives your engine clean'?
What was posted is basically propaganda, just follow the money from big oil to the NMMA to manufacturers...etc. They led a misinformation campaign over the new Unleaded 88 which basically stated the objection to allowing the blend is Americans are too stupid to read.
The water separator and any water in your fuel tank has to do with condensation and extended storage with a vented fuel system in wet conditions. With or without the ethanol, the water will be there if it's introduced. WITH ethanol, much of that amount is absorbed and burned off harmlessly. Without, it's there, and at the fuel pick up. That, at least, is truth.
Ethanol needs no stabilization. Think about it, leave a quart of gasoline in one container, and a quart of corn whiskey in another. See which one goes bad.
I travel the US and have never seen a gas station yet where e10 is not for sale. The 15% blend is called Unleaded 88, in association with the octane rating.
All but very old outboards will run e10 very well, and all engines of recent manufacture are designed to. Another consideration, since motorists will not by ethanol free fuel much; that fuel will sit in a tank for an extended period.
Note all the additives ADVERTISED by oil companies as solvents and cleaners in the gasoline they sell. Yet they rail against ethanol. There's your sign.
10% of the market is billions. Follow the money, and check out the Oklahoma State studies and many others done independently. e10 is the perfect fuel for your boat. |
