When we first started producing ethanol fuels many studies were done, the largest issue other then the separation factor is moisture absortion. Ethanol attracts moisture out of the air very rapidly. We were seeing a 2-3% plus, growth in moisture over a 30 day span in storage tanks that were not kept completly full. Meaning a 3000 gl tank would actualy end up with a LOT of water in it after a 30 day period. Keeping your tank full may be a hassle but it is well worth it, as well as using the additives. QMI out of Lakeland has a product called triple T (Tune That Tank) that is without a doubt one of the best water dispersers I have ever seen.
