Bio-diesel / Is it a good or bad thing for the engine ?

I have run into problems with my 2013 Chevy diesel failing regen do to the fuel not igniting through that ninth injector. Now not only is there a bio diesel out there but another form called BioMass diesel. Reading from the internet says it comes from algae or animal fats.

These fuels that lower the egts the truck runs can and have caused problems with the new emmision systems required on the diesel trucks. They need heat to burn off the soot it collects.
