Was helping a friend last evening with his WVO processing. For a basic system, I was mildly impressed with his process. Please tell me what you think as I would like to give him some educated feedback. He has been doing it this way for about a year so far with no major issues.

His process.

Gather WVO in the cubies and let it settle for a few weeks.

Take the pre-settled WVO and pour it through a homemade rough filter made from window screen into a large stainless steel pot.

Heat the WVO to about 150 degrees to check for water.

Filter the warm WVO through a 75 micron (absolute) filter into 5 gallon pails.

Let filtered WVO cool and settle overnight

Gravity filter the 75 micron filtered WVO through a 5 micron sock filter into a plastic 55 gallon drum.

Drain off WVO through a tap inserted four inches from the bottom of the barrel when needed (he says this ensures he doesn't get any residual sediment)

Add RUG to the drained off WVO for a 95% WVO/5% RUG mix

Pour into cars second tank and use!
