Can the duramax burn biodiesel without any problems?

I've been running a 20% blend in the Duramax since new. I've been running my VW TDI on 20% during winters and up to 50% in the summers. No fuel related problems yet. My Duramax gets 19-21 mpg on the highway, and my VW gets 47-51 mpg.

I get my soy biodiesel from our local farmers Coop (They buy it from West Central in Ralston, IA) . They mix it at about 1% in their fuel they pump at the station, but they will pump straight B100 into containers if you go to their warehouse.
