PSA (Citroën/Peugeot) says its HDi turbodiesels can take up to 30% biodiesel, but it has to be premixed - you can't just pour 7 gallons of regular diesel, followed by 3 gallons of 100% bio, into your tank. Plus normal fuels here in the EU (not sure about the US) already have 5% biocomponents in them, more to satisfy the farming lobby than for cleaner emissions.

I'll agree with the increased fuel consumption and decreased reliability of DPF systems, however, urea is used for SCR--not DPF. Some vehicles (including mine) were manufactured with a DPF, but not a SCR. The DPF is for particulates while the SCR is for NOx. My truck was made with a lean NOx trap (adsorber) rather than an SCR system.
