Neat video. That would be great fun.
The trucks were all diesel.
I think ordinary diesel turns to jelly in very cold conditions so it's not much good for a cold start.
Jet A1 is basically just kero with a few additives so it remains liquid at high altitude / low pressure / and more importantly, low temperature.
So, jet fuel works reasonably well in polar regions because its made to work in the low temps you get at 30,000 ft plus.
Petrol of any sort at those temperatures is extremely hard to burn as it doesn't vaporise.
Liquid petrol does not burn, only the vapours it gives off will burn.
In fact, liquid anything does not burn. Only the vapors they give off burn.
