Mfg's are making a killing on the B100. Soy oil is made when making the bean paste for use in food stuff's and they make a lot of cooking oil from that, even after selling oil to fuel makers. They have so much left over from the process even after sell it for cooking and other types of oil that most is dump. They can do that because it is a non bio hazard.
One of the problems that still give the B100 makes fits is lower the jell point. The crap starts getting thick below about 75* F and turns solid at 32* F and as yet no additive to prevent other then heavy mixing with dino fuel.
