ive also heard of peeps adding white spirit, but ive never used it. may be worth a try?
White spirit is clear; brings darker colours back to a pale yellow diesel colour!
To be honest, if it burns, goes in the tank, and offers enough lubrication to the pump while not being overly thick, it will make a diesel go.
In the winter if your going on any long journeys, start it up on DERV, and then blast in x litres of your favourite juice, once at the destination and tank has used most of the fuel, throw in a gallon of derv let it mix this around and draw it into the fuel system, this will help it start if your going to let the engine cool. Once your off again, start it back up, and throw in another x litres for the return.
If you keep it garaged at night you will have less of a cold morning starting problem. I have a button for my glows, so I would just give it an extra few seconds and its fine. You could always put in a glow override circuit, it would not be difficult, get the combustion chamber red hot, then crank.
