BioDieselNow - Renewable biodiesel fuel

The best thing to do is get some jars and put some mix in them, one like b100 , next b80, next b60,next b40 and so one then put them out side record the temp and see what happens the the mixes at what temps ex, b100 might gell up at 30deg. f and b80 at 27deg. f But you get the picture so just have fun...
