I mean that the common rail can handle the biodiesel, but not the VO as easily. This, I believe, is because of the viscosity of VO. Biodiesel has a very similar viscosity to diesel, which is why it does not have to be heated for use in a diesel engine. Even with heating the VO it will never get to the same viscosity of petro-diesel, although it does get reasonably close. Generally common rail is a much more advance fuel injection system compared to the inline pumps on older diesels, and thus making it less tolerant to higher viscosity fuels.
