It ought to take months for your oil to go rancid, considering it lasts a week or so exposed to air at high temperatures. Displace air with carbon dioxide - when the tank (smaller is better) is just about full put the nozzle of a MIG gun in and press the trigger - 18 litres/ minute should go in - assuming you have turned off the welding current (there is usually such a function for starting out a new roll of wire) and released tension roller on the wire, then seal. Or route the exhaust of your homebrew kit into the tank with cap on but loose, preferably via some drier chemical. If the oil is clean and dry it should last years.. ----- Original Message ----- From: "maudessen" <[EMAIL PROTECTED]> To: <biofuel@yahoogroups.com> Sent: Friday, May 28, 2004 11:36 AM Subject: [biofuel] Re: proper storage of used cooking oil to make it last longest possible
