I believe it is down to whatever the Biodiesel is made out of. Bio based on Rapseed will have the lowest gel point, and should be liquid at temps below 0C, maybe lower. Soy and Sunflower have slightly higher gel points but I would think should still be liquid 0-10C! There are a lot of home-brew bio makers here in UK (check
http://www.vegetableoildiesel.co.uk) and most of those run it all year round (including minus temps blended with winteriser, pump diesel, or even unleaded) - bear in mind that here in UK we are VERY lucky to get brief temps of 30C. If the Bio is made with Palm Oil that could explain it - Palm Oil is solid at room temps, so creates a Bio that gels at higher temps.... BUT, I believe if made well it's Bio should still be liquid at 10C? Maybe just a bad batch with soaps/HMPE's?
Edit - are you talking degrees C or degrees F?
