that is simply not true. ethanol will not attract water out of the atmosphere
Well if it's not attracting water out of the atmosphere, enlighten us where it's coming from. I'm sure it's not coming from the garden hose.
short trips. when you start a car/truck/motorcycle the change in temprature in the fuel tank and the change in volume in the tank its self cause mosit air to be pulled in. then it cools down and the moisture falls out of its vapour state and eventualy settles to the bottom of the tank. thats why people who do a lot of grocery trips seam to need to use methanol (gas line antifreeze) in the winter. this allows water to mix with the fuel but it doesnt adsorb it either and isn't good to use in moderen vehicles. a water filter is the best way to do it.
The origin of the claim is that ethanol is classified as a "hygroscopic" substance, note the spelling: hygroscopic...". It is HYGRO, with the letter "G." and that the general dictionary definition for a hygroscopic substance is that it can attract moisture from its enviroment. so it doesnt adsorb it but it atracts it. for example if you put a open bottle of whisky on the counter, the level wont go up.
