Drying heating oil

Okay, here we enjoy a practical application of chemistry.

I want to remove the water, if any, from my household, #2 fuel oil tank, roughly 275 gallons capacity. The fuel level is getting low so I was thinking this would be a great time to throw some dry methanol in there. Why wouldn't that work?

Water accumulation in Diesel fuel is a widespread problem. What do the guys that drive the Big Rigs do?

These guys have some tips, which naturally involve you buying their products.

Me, I'm cheap. I might pump it all out. Flush the tank out, filter the old fuel, and start fresh. Methanol might work for water, but not for other kinds of crud.

Almost all the water will be under the diesel. I've always just siphoned it off the bottom.

As long as you system can tolerate flammable vapors (like if you were to use methanol) you could throw some E-85 in there. The 85% ethanol should soak up the water, and it would probably be cheaper than the methanol.

Of course, siphoning or draining the water from the bottom is the preferable solution.
