One of the reported side effects of adding biodiesel is that it often loosens up deposits of accumulated gunk in the tank - yours and the filling station. That can and does clog fuel filters, though the problem should go away once the filters have been replaced a few times (thus cleaning out the gunk). And some bio-diesel may have larger molecules than petro diesel, or form collections of molecules, that do not readily pass thru filters. Either of those may have been what Will's drivers were encountering. Using a higher micron filter lets some of the stuff through, so the filters don't clog as quickly, but runs the risk that a piece of dirt will get through and damage an injector. That may be low risk, but injectors are a very expensive repair.
5% biodiesel is probably little or no risk. 10% is 'maybe' and, from what I hear, up around 15-20% the reports of problems start to get high.
