Or maybe it won't work at all...

Decreasing the viscosity of fuel is great... it makes your pump work less, and it flows easier through the injectors. When it comes to the time to actually burn the fuel, the viscosity doesn't mean much when the system is already working to vaporize the fuel to such an efficient level.

Lets say, at best, that it was already 90% efficient at vaporization. Reducing the viscosity of the fuel to ANY extent could only make it a max of 10% better. The closer to 100% you get, the less effect your work has, meaning that it would take a fluid with NO viscosity to reach 99% vaporization efficiency, given the best possible circumstances.

I'm not saying 100% is impossible, but you're not going to get it by adding water to your diesel.
