Well I will give you the other perspective. My brother manages a large fuel wholesaler/retailer with heavy emphasis on farming and trucking. I asked him this about biodiesel when I first got my Eagle with the old mech. 8.3 Cummins. He laughed and said when they first started selling biodiesel (they even had an investment in a plant) it did not take long before complaints started to coming in about bad fuel from both farmers and truckers. Since they had not had a bad fuel complaint in years they had several analysis done they came back good but the lab did tell them that 10% biodiesel is a great solvent and what they were seeing was the gunk built up in fuel lines and tanks that was being cleaned up and plugging the filters. They even bought cases of filters for common engines and supplied them free to customers for a period of time. Now once the cleansing process was over the problem seemed to be solved and engine use returned to normal.
The upshot was he told me anything over 5% will work but be sure and have filters on hand and don't be surprised when you go through several filter changes. Myself I have avoided using biodeisel so far and will even call ahead on anticipated fuel stops to verify fuel content.
