That price was taking into consideration my processing costs as well (electricity, clean up materials, etc). It has definitely gone up since then from what I have seen. My diesel actually ran quieter when on VO. When injected at the proper temp, VO burns very similar to diesel. If I remember correctly, my system would not switch over to VO till the VO temp was at 170deg. The biggest thing was remembering to purge back to diesel before you reached your destination.
