Just bought the raw chemicals to start makin my own. 50.12 lb of sodium hydroxide known as lye = $27 and change and the methanol was $211 and change for 54 gallons but im starting with small more expensive quantities. So the free oil and these numbers equals what, 54 methanol makes about 540 gallons of bio and the lye will last me anywhere between 800 to 900 gallons by using i think a little over 6 oz per 100 gall..anyone else out here in AZ?
