Many things are not possible, me being an engineer and all ! Ask my wife !! I have to totally disagree atsah. (There have been many threads on this issue.) No matter where you live and no matter what my background is, a 50/50 mix of #1 and #2 diesel fuel will cure any potential gelling problems you may have without use of additives.
That method is used more than any other to prevent fuel from gelling. I learned it from dozer operators in northern Vermont. Ask your own local heavy equipment operators.
In the event that neither they nor I can "get it across to you," see
Cold Weather Fuel Issues: The Safe Answer is Gelling | Fleet Owner where it says:
All of this can be attributed to poor maintenance ... as well as a poor understanding of fuel and poor communication with your fuel supplier. Some believe everything can be solved with pour depressants and additives. But actually there is a point you need kerosene. And if you are buying fuel at a truck stop, it may be treated with additives, but in most cases not blended. Kerosene is expensive and most truck stops choose not to blend because fleets do not want to pay for gel insurance.
People way up in the northern US and Canada do not have any issues with fuel. They have figured our how to maintain their fuel below ground, above ground and most important on the ground. And you will see plenty of signs for KERO. What a surprise.
...
Most reports I have seen show that a 50/50 mix of #1 and #2 yield a gel point around 36 below zero F. Roughly the same as your antifreeze mix in the radiator. That sets a practical lower temp limit that will make you forget gelling.
I will grant you that using additives can be of value. It is absolutely NOT required.
