I have run bio through my truck since I bought it a year ago. I have run probably 10 tanks of b100 and 6 tanks of b30(winter time) I have just lost some power. I do have to say these CRD engines are finicky though. I had a batch I didn't dewater well enough and didn't convert completely and the truck did not like it when it was cold but not cold enough to kick on the grid heater. Ran rough and smoked until the cylinder temp came up. I just put 10 gallons of#2 in it and chaged the filter to dilute the bad stuff and started to dry my fuel and test it a always before using it. No problems now.
