time is key in making bio. i make 80 gallons over 4 days. it's only a couple hours of work each day, but settling is the big factor. i dewater (~300*) and it takes a day for the oil to cool. the next day i process and let it settle overnight. then i dry wash and let the mangesol settle out over night. this is way easier than trying to filter it all out. then i filter 3x @ 1micron. my dad and i built the machines "industrial" style.

luckily, 80 gallons lasts me a good while.
