Took about 10 minutes to collect the oil cubies from either my work or local restaurant. I filtered it in succession this way, simply poured it through a filter made from window screen to remove larger chunks, the screen sat above a five gallon bucket with a 5 micron screen on it, and gravity drained into a 2 micron sock filter which drained into a 55 gallon plastic drum. I tapped the drum about 3 inches from the bottom to draw off the oil. I built up enough of a supply so I always had 20 gallons ready to go at a notice, while anything else was taking its time to settle out. So my physical involvement was......moving a few oil cubies into the car trunk, taking them out of the trunk, pouring into my filter setup after they settled, and drawing off the oil. All in all, about 20 minutes hands on labor a week, and a few weeks to allow settling (like I said, I had a supply already built up so waiting was not an issue).

That's fantastic. Hugely less hassle than what I've read about others going through.
