Using biofuels for heat?
 

Obviously this isn't the best way to go with all of the available options. However, I have one of those torpedo multiple fuel heaters. It takes diesel, kerosene, etc. Has anyone put biodiesel through these things to see how it works? I'd love to at least feel somewhat better about using it. I normally run kerosene, but I try to avoid using it as much as possible. I'd assume as long as gelling isn't a problem it should be okay? I could really use some heat in the garage!
