The driers are meant to pull the water up into solution, which solves the freezing at the bottom of the tank issue, but not the other ones. Plus, you don't really want that methanol in your fuel either. I would recommend just getting good quality oil (shop around, if necessary), and doing a good settle/filter.

If you are feeling 'experimental', then try a small quantity of copolymer based pool flocculant mixed in during the 'settling' time. There are two kinds of pool flocculant, one is alum based, and the other is 'polymer' based, you want the polymer kind. Some folks have had very good luck with a small amount of that pulling out a surprising quantity of water and particles in suspension in just a few days time, making the final filtration much easier. But like I said, its still experimental.

peace,
sam
