Most of what I've read implies that B100 has less btu/gallon the #2 diesel. However I think this does vary based on what feedstock it's made of. I know that when I ran a '74 mercedes diesel from SVO instead of diesel, all of the knocking at idle went away and you could hear the lifters again, and biodiesel made some of the knocking go away, though not all. No quantitative data on this unfortuneatly.
I looked up the ratings of #1 and #2 diesel, and found that is is supposedly about 45 for #1, and 40 for #2. The solvent effect is interesting. Perhaps keeping the injector clean is the benefit? But I thought that modern diesel had detergents and such included in it to do this.
