Diesel Fuel

Its late and I don't feel like conducting a web search for an answer so I'm going to ask my fellow diesel owners a fuel question. I purchased a 2011 Chevy Silverado 3500HD 6.6L diesel in South Carolina. Since then I've used the Ultra Low Sulfur Diesel(ULSD) fuel which is clearly marked on the fuel pump. We just drove from SC to Omaha, NE and in several states there is no ULSD fuel but diesel such as Biofuel and D2 diesel. I quickly glanced through the owners manual and it appears using either of these fuels is OK but again I didn't study the owners manual, so my question is, using biofuel, D2 and ULSD and at times mixing between the three during refueling times, will this have any adverse effect on my engine? Do you use any additives with any of the fuels mentioned? I'm going to read the owners manual in the next day or two but I wanted to hear from other diesel owners, this is my first diesel also. Thanks and be safe out there!
