I even had mine start without the block heater when it was -18ºF overnight; I had forgotten to turn it on (shame on me), but it did turn over and it started fine.

That is impressive. I wouldn't even bother trying to start mine when it was that cold, and not plugged in. :-laf



My biggest problem with starting a diesel that is that cold, would be that the oil is very thick at those temps, and would be slow to come up to pressure. Now if you have syn. oil or a thinner vicosity than 15-40, it wouldn't be as bad. I can tell you, that 20W-50 pours like cold corn syrup or honey, when it is really cold.
