There have been tests done on the polymerization properties of diesel, biodiesel, SVO, WVO, and WVO cut with 10% diesel. Only straight WVO (even filtered and dewatered) causes polymerization issues. When cut with D2, that polymerization is about 99% eliminated. So... if you're running SVO, then if it's hot enough it's fine. Not the case with WVO.

That is a very common misconception. Polymerization is a fairly complex reaction involving FFA's, oxygen, heat, a catalyst (steel and copper being the best), and time. SVO is not completely without FFA's and will polymerize given the right conditions. The few actual documented tests comparing different fuels produced mixed results. Cutting with D2 will at best slow the process down to a negligable rate.
