What site(s) was you looking at for the WVO diesel mix? Lat time I knew for direct injection type systems people were still testing using SVO or WVO in larger mixture percentages or just heating it and using at 100%. The pre-chamber for better atomization was the way to go like the Mercs. I'd be curious to see the injection tests after using for a long time. Would be great to not have to make BioD for a DI like the PSDs. What were the percentages of mixtures to combat viscosity problems or was the injection pressures of PSD enough to not have to worry on high %'s about that?
