well, without any research... i think i can attest why- dry gas in
isopropyl alcohol which absorbs water molecules.... so why wouldn't ethanol, an
alcohol with a similar carbon chain, bond to water molecules as well?
i guess in the end, its a quantity issue, a full tank, treated or not, will
shelf-life better than just a few gallons....
not good.... i have some cars that even when i rotate my spots in the
garage sit almost a year just because i'll have to move over 10 just to get to
one on a given day... but cant complain if theyre all safe and dry
inside.
