Unsure if this topic has been raised previously ?
Recently bought one of the above to heat the shed, I have 600L of 5 year old distillate which was treated with Penrite stabiliser but a little wary about using it in my common rail rail ute.
This thing is excellent, thinking of folks using old kero heaters and such with kero being $4 per litre and kero heaters being a little stinky and inefficient.
Heaps of info on Youtube so will not go into detail but also thinking if you had an old diesel engine that is hard to cold start these things can be programmed to auto start / shut down on timer, 12V /24V required but that could easily be supplied by tractor of truck battery as could fuel supply if necessary.
I have no connection with advertiser below but found this to be by far the best price, the machine is very good and identical to other "brand name" units which cost $45.00 more.

I have had great fun installing and nice to be warm in the shed without using bloody expensive mains power when solar is not running.
