How cold is too cold for a diesel engine?

Anything below 9 degrees is not going to work. Even after lowering the temperature to 5 Celsius cans of diesel will malfunction.
How do I keep my diesel from freezing?
One way to avoid diesel fuel from crystallizing (or gelling) is to use an anti-gel fuel supplement. Diesel fuel anti-gels are simply added to the fuel (just drop it in the fuel tank). Anti-gels drop the freezing point of diesel fuel so that it is less likely to freeze in cold temperatures.
