It does not require labeling at the pump unless it is 5% or more. A simple 2% biodiesel blend will provide more actual lubricity than anything off the shelf. And it is included right at the pump at no extra charge.
Fleets, even with older equipment, have not experienced any more engine downtime than normal because of the LSD/ULSD game. Only equipment that the fuel systems and such were not properly maintained to begin with ever seemed to have any real trouble.
HD diesels aren't built to the same standards as passenger car diesels though. A common rail passenger car diesel operating on 520 µm wsd fuel is only rated for 120,000 miles, and at 460µm for 200,000 miles. Go down to 300µm and the injection equipment has near endless life (700,000 miles IIRC).
