They stated there were no long term tests of soydiesel because the engines haven't lasted long enough to run accurate tests. There is also the issue of legally burning vegie oil and meeting ASTM standards with it.

Maybe there is a difference between the oil you are burning and what he is talking about, I can't say for sure. But yes, do keep us posted as to how your engine runs and holds up to the vegie oil. I think it's critical that we start finding alternate fuel sources with the rising fuel prices. But for now I'm going to stick with my soybean biodiesel, I just don't feel comfortable putting all those impurities through my engine yet.
