Another BIO question
Just curious to know if anybody that does run bio in their rig (B20, B99, B100) uses any additives like a cold weather/ anti-gel formula? It's slowly getting colder and don't want any issues. I've found a few retailers in my area that have B20 and B99 and thought I'd give it a shot.

biodiesel.org has tons of info on everything bio related, check it out. There is also a Bio Diesel/Alternative Fuel section on this site that has tons of info. I personaly run all blends, mostly b99 and have never had gelling issues at all. I do live in southern california so it doesn't get that cold around here even in the winter. Last winter i was up in the local mountains on a snowboarding trip and was running soy b99 with night time temps of 32 degs and truck started up perfect in the morning. This year i might use some anti gel additives or run like a b80-b90 blend just to be on the safe side. I don't know if you have heard of the "freezer test" but its basically just what it sounds like. Put your biodiesel in the freezer with a thermometer and see for you self what it clouds or gels out. Different feed stocks have different gel points so keep that in mind.
