No injector adjustment???

I've got espars on my truck but they usually dont work very well below -25c or so. Normally if it gets that cold I will leave the truck run but guys take days off, go on vacations and such and dont wanna leave a truck running while they are gone.

This year I am running 0w40 oil and trying out some fuel additives, I dont usually run fuel additives but I have a theory that the espars tiny little fuel lines are gelling the fuel which is why they wont fire when that cold.
