Hey there,
thanks for the plug for my book and all.
So, yes, we have weird problems OCCASIONALLY on 6.0's, and no one knows why. It looks like the times when this has happened, it might have been 'off-spec' fuel, but again, I dont have a sample of what any of the peopel were running and no one's tested the fuel that I know of. However, blends of biodiesel and petrodiesel seem to do just fine as could be expected.
The symptoms of the 6.0/B100 biodiesel problem (B100 = 100% biodiesel, B50- 50%/50% biodiesel and petroleum diesel mix, B20- 20% biodiesel and 80% petroleum diesel) are that people see strange sorts of fuel filter clogging- little particles fill up their filter until they add some diesel- there's a guess that the high pressure somehow causes some biodiesel or some contaminant in that biodiesel to break down and form sediments. This is different than the 'normal' filter clogging that everyone else with biodiesel MAY experience when we first start using biodiesel or SVO (biodiesel cleans out caked on crap in your fuel system, so for the first tankful, you may see the filter clog if there was a lot of sludge in your fuel tank- this is DIFFERENT than what the 6.0 problems seems to be)
Here's mine and many others' website on how to make biodiesel:

It's a little like 'tech articles' here- people from all over the world wrote the articles.
Also, the book Sagebel is referring to is here:

The 'tour' thing was last fall, I'm not doing it this year unfortunately.
