Welcome to FTE. Yes you can run B99 without any engine modifications, although it would be wise to carry a spare set of fuel filters since Bio will clean out your fuel lines and tank. If you have any gunk in there, it may plug up a filter.
If you get a bad batch of Bio that causes a problem, it will not be covered under warranty. Just like if you get some bad old fashioned diesel. That's not a warranty item either. Ford's position has been a max of B5, so if there are any concerns, it would be wise to dilute the fuel with as much regular diesel as possible before taking it in.

Bio diesel and engine oil
A mechanic told me that when the engine burns fuel not all is burned and the unburned fuel drips into the engine oil. In the case of Bio its solvents will break down the oil quicker. Have you noticed any thing like that? How often do you change your oil?

I use Amsoil and change at 15K with a filter change at 7,500. Due for a filter change/oil analysis in about 1,500 miles so I can post my results then.

I just stuck with the 5k change interval when I was running bio (supply issues right now). If you're wanting to go past 5k then an oil analysis is recommended.
