Someone mention "anti gel".
Our winter diesel here in Alaska has a proper additive package. But a good fuel supplement helps. Especially considering that winter grade diesel might not have been in the tank when that first Alaskan cold spell kicks off. Start mildly treating the fuel in September. Then lay it on thick come November. I actually pour 8 oz of the stuff, to a fill-up.
I've found hotshots winter diesel is good sht. All sorts of improvements:
Deicer
Increased cold pour point
Lubricity
Cetane boost.
You can literally hear the clatter disappear on that 30 below zero start up. I think it's the cetane booster in the mix, but dunno.
Coldest I've ever started a diesel:
57 below zero ambient, 6bt cummins. My fkn radiator fluid looked like a green slushy.
