I understand that the DPF is a problem running B100 because the ecu injects extra fuel during the post injection to burn off the collection in the DPF. But, thought that with B100 you would not have as large of problem because it burns cleaner. I would think if you could skip the entire post injection, run B100 and you would have better lube, lower emission, no sulpher, and get better mpg (no injection of extra fuel for non performance use). If I am wrong (which I most likely am) please explain why we need the DPF if we have no sulpher in the fuel and why it is needed still. Thanks : )
