I would certainly like to see more details into the test procedure.

Diesel mixes perfectly well with gas and does not separate, but there can be side effects to the vapor system.
Octane no longer has anything to do with actual octane in the fuel ron and ran and whoever else are apart of an "octane" test and only have to do with the likelyhood of knock and nothing to do with the percentage of the physical chemicals like octane.
As I stated diesel is much lower "octane" than kerosene when tested for knock properties. In the early 1900's Kerosene was gasoline. Kerosene will burn in lamps, diesel does not do so very well. A hydrocarbon mix is quite complex in its behavior so speculating what it might do will be difficult but it is unlikely to do anything very desirable.
Anyway Diesel should be capable of burning at certain percentages in most engines, especially those run at lower RPM or higher compression.
Low compression diesel RC airplane motors exist, so diesel can operate in lower compression environments assuming you preheat the motor.
How well is another thing Mwebb definately nailed it that it probably won't burn well in many engines.
That said some people may see a fuel economy increase on certain engines, but it may be because the diesel does not burn well and dopes the O2 sensor into leaning out and in turn burn out the cat? Who knows I would say Caveot Emptor, don't try.
