An upflow system helps a lot in eliminating water and antifreeze from oil. I use if for every batch I run. It is cheap, simple, effective and costs nothing to run. There are a number of threads that contain information about it here. All you need is a couple of good quality 55 gallon drums, a length of 2" auto exhaust pipe, some valves and a little welding and you are in business. Get a short lenght of 2" pipe, cut it in half. Measure the exhaust pipe so that it comes down to about 8" above the bottom of the lower barrel, cut it there and insert it in one half of the 2" pipe. Weld on the cut end so the threads are not damaged on the other end. Weld the two halves of 2" pipe back together where you cut it. Screw the pipe into the lower barrel so that the exhaust is above the bottom. Cut the second barrel in half or maybe a little longer than that for your top barrel. Screw it onto the stub of 2" pipe. Make sure that the 3/4 bung is securly closed on the top barrel. Plumb the bottom 3/4" bung so that you have a valve to control the flow and plumb it into the mixing barrel you are going to use. I put a Banjo strainer between my barrels to pick up any solids that might tag along on the flow. Crack the valve so pressure can release on the lower barrel, then fill both barrels until you get flow. Close the bottom barrel and complete the fill of the top barrel. When you are filled, cover the open top of the upper barrel. Crack the valve so you get a very slow flow (two days to fill your mixing barrel to the right amount). Water, solids, really heavy petroleum products and antifreeze gets left behind in the bottom barrel and can be drained off the bottom. Your going to need a valve down there and that is easy to do with a bulkhead fitting. Every batch of fuel I make goes through an upflow and I do not have problems with water.
Most of the people on this forum use gas with ethanol to make their W85. I have ethanol free gas available in my area so I use it. I don't think it is an issue if you keep making fresh fuel as you use it and don't let large batches sit for a long period of time.
