What the concensus here - is 1600 bar injection pressure engine (new VW common rail) ready for extended, multiseason biodiesel use w/o additional problems?
I mean, the current crop of diesel engineers are set on making diesel spray as fine as possible, and under high pressure. What's a change in fuel viscosity going to do to an injection system like this after extended use? I'm talking about bio that meets ASTM-spec yet still varies from the viscosity of dino diesel or ULSD.
Now, the ALH engine and it's lower injection pressures is more than tolerant of extended B100 use, as everyone here knows. Finally we're seeing biodiesel availability and pricing "hitting its stride" in North America. Are we now going to get the rug pulled out from under us by Common Rail sensitivity to anything >B5 ?!
Input from the JeepCRD, Sprinter, E320 CDI, or heavy duty domestic truck crowd or weblinks to their discussion would certainly be relevant here.
