Number one diesel like they sell up north has additives and some paraffin to keep it from gelling.
You could buy some of the commercial anti-gelling agents to lower the temperature. I spoke with my brother in Alaska yesterday about this and he says they make a special additive you put in the diesel and it keeps it from gelling down to -40. They also use engine heaters and tank heaters there. mel -----Original Message----- From: Appal Energy [mailto:[EMAIL PROTECTED] Sent: Tuesday, December 28, 2004 9:01 PM To: [EMAIL PROTECTED] Subject: Re: [Biofuel] cold climate biodiesel production Mike, That's as normal as the sun rising in the east. Expect to start having gel/solidification problems at around 40*F with WVO esters. The problem isn't that the oil is used, but that animal fats are generally present in WVO. Also, much WVO is partially hydrogenated (looks like veg shortening prior to its first use). This imparts some of the same properties as animal fats, as the carbon chains are more saturated. You might be able to push the useable temp for B-100 from WVO a few degrees lower than 40*F as long as that temp is a fleeting overnight low, not a steady state. Nasty business trying to get a diesel to start when it's got solidified "crisco" in its veins. Can sure wreck your plans for several hours, presuming you've got a tent or a garage you can roll your disabled car into. Longer if you don't.

Is this normal or have I picked up some bad wvo? thanks Mike _______________________________________________ Biofuel mailing list [EMAIL PROTECTED] http://wwia.org/mailman/listinfo.cgi/biofuel Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Biofuel archives at Infoarchive.net (searchable): http://infoarchive.net/sgroup/biofuel/ _______________________________________________ Biofuel mailing list [EMAIL PROTECTED] http://wwia.org/mailman/listinfo.cgi/biofuel Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Biofuel archives at Infoarchive.net (searchable): http://infoarchive.net/sgroup/biofuel/ -- No virus found in this incoming message.
