Luke,
If your WVO was used to cook meat such as chicken, you will have some
animal fat which may be causing the middle layer. It will still make
excellent warm weather fuel.
Of course, it might be water.
Heat a small sample to get the water to drop out. Take some of the dried
WVO and let it cool. If it remains clear, you had water. If it clouds upon
cooling it probably contains animal fat.
