Lies. I've pumped tanks that took on enough water to render a boat dead from from water absorption by ethanol fuel. Systems that checked out to have zero leaks anywhere in the system to allow water intrusion. The water was completely separated from the fuel. Pumped a solid gallon or more before stank fuel came out.[/
I hate getting into ethanol arguments.
90% humidity air at 86 degrees would take 138 cubic meters of air to hold a gallon of water. .
No, it's YOU who doesn't get it.
10 gallons of E10 has … lets calculate it out, carry the zero, and ignoring rounding errors … a gallon of ethanol.
When there is sufficient water in the two phase mixture, the entire ethanol component bombs out, because it prefers greatly to be with the water than the gasoline.
That's a WHOLE gallon of stuff that's sitting at the bottom of the tank.
Well it's more than a gallon, as it's got the water in it as well that it got out of the atmosphere...and note that the atmosphere around a boat is pretty humid...PLUS it wasn't used over winter, which is typically the coldest pat of the year.
Below is a chart of the amount of water it takes per volume of E10 to precipitate a phase change...above the line and you are golden...below the line and the ethanol bombs out (with the attached water)
Note:
* that it's temperature dependent,
* once it's dropped out, raising the temperature doesn't make it go back into solution
* how small a quantity it is...about a percent.
While I don't recognise the technique that you used as valid doesn't that bring it to under a month ?
Where are 2 quarts of water coming from?
The gas tank doesn't breathe that much. Is your kid pouring their drink in ?
Please.
You can't get any better gas dryer than ethanol. And you politically motivated are trying to spin it as a negative. The gas dryer additive used to come in a 12oz bottle and that was more than enough to dry a tank out.
As a side note on this, Traditionally the yellow bottle gas line antifreeze was methanol and methanol had a much lower phase separation point than ethanol. Gasoline also absorbs water and has a phase separation point obviously much lower than any mtbe, methanol, or ethanol mixtures.
So to continue on this the reason everyone sees this larger amount of separated fluid in ethanol mixtures verses straight gasoline or other mixtures is due to the amount of water than can be absorbed before the separation. As stated in several articles it is very unlikely to get enough water out of the air to cause it as all of the modes pull less water from the air and stop when they are saturated. This happens before phase separation happen. Then that leave the only means of gaining the amount of water is condensation or intrusion. This volume of water getting into the system as stated in various articles and by anyone's math is very difficult by air alone. I wish I could find a formula to figure out how fast and how much water can remove from the air but even doing the math to figure out how to circulate that much water in the air through the system without any of it being removed is difficult even is a poorly sealed system.
