Prior to buying my current diesel, I was looking at the big gassers as a replacement for my former diesel. The negatives were operating range on the same quantity of fuel and engine output passed on fuel. I could get really cheap operation out of a gasser running on LPG, but the derated power and reduced range convinced me that running this cleaner cheaper fuel was not in my best interest. CNG penciled out about the same, but availability was issue for me. In my case even running the gasser on gasoline was not enough, since I frequent mountain passes and my loads are continuing to get heavier. Don't even get me going on the subsidized waste of gasohol and its instability and poor performance...
I have seen propane and water injection systems that help combustion, so this "premix" does not surprise me. I'm just trying to understand what the pros and cons are of running GDiesel.
