B99 in a 6.7?

I ran B99 for thousands of miles in 2011 6.7 without an issues - other than much less frequent regens and I used a little more DEF (got about 600 miles to the gal). Oil changes are supposed to be sooner than waiting for the Oil Change message to pop-up. (Every 3k miles).
Now it's possible the newer regen strategies may not like it or it may not help lengthen the distances between regens any more.
Really, the sweet spot is B20 for a variety of reasons.
This was using regular Transtesterfied Soy Bean Oil stock for Bio - it's what the local person sold near me in Miami. The new Hydrogen Cracked stuff that's pretty much only in California I don't have experience at all with - and that is supposed to be able to be burned at the B99 level without any issues too.

There are more things to consider when running bio - even at the B20 level... Anything above B20 and your are risking warranty denial for engine/fuel system problems.

Any water from any source in the fuel is a no-no in an modern diesel. Yes, Bio is more hydroscopic than regular diesel fuel. Never ran into that issue and know plenty of people that have put tens of thousands of miles on Bio without issues.
There are other issues with B99, like lower power and in older diesels it degrades rubber fuel lines, ones not made out of Viton (sp?). It really cleans the tank and lines of sludge so it can clog fuel filters. Since I can't get it and really run it due to the climate I live in, I am not following it anymore.
I only ran commercially made, quality controlled, ASTM certified bio-diesel. No backyard brew. Because of the cleaning qualities of it, I liked running a tank of B99 through right before a fuel filter change.
