Diesel Gelling

What temperature does #2 diesel start "gelling"? What would be a ratio of kerosene/diesel to prevent gelling? I've read the bottles of "additives", but they claim the "mix time" needs to take place above 48-50 degrees, that's not going to happen this fall for us anymore 

All I know is that it's delivered to the farm via the local CO-OP, has been for years but have NEVER had concerns about gelling because "normally" the harvest/ fall tillage has been done 5 weeks ago 

Best way to keep it from gelling, is a clean, new filter, and some anti gelling elixer, put in every tankful of fuel, after the frost date, in your area.  A filter heated by a bypass loop of engine coolant, is a nice option, too...

Wind chill is not a factor! It might cool off more quickly in a wind, but it doesn’t go below the ambient air temperature.

When I use to grind feed with 185 on a single diget day after being plugged in couple tractor would start immediately and run fine in shed.   Hook to grinder and back up to oats bin and as soon as I would get off tractor it would shut offf. Fuel gelled up. I finally put some insulation around sediment bowl to keep wind offf. No more problem

The temperature due to wind chill cannot go below the air temperature. But Exposed, it will cool off more rapidly down to the air temp.

Think about it. Why wouldn’t every radiator freeze solid due to wind chill effects if that were the case?

All the wind chill does is mean the wind is blowing harder so it blows away any engine heat you're trying to preserve to keep filter on side of engine or transmission warmer. Wind affects it, not the wind chill factor though. Essentially there's no warm place to hide lol!

The temperature of windless air that would have the same effect on exposed human skin as a particular combination of wind speed and air temperature. As the wind blows faster, heat is lost more quickly from exposed skin, making a person feel colder even though the air temperature remains the same. Also called chill factor

So, how does "colder then a well drillers azz" fit into the picture?

Wind chill only effects things that generate heat or have latent heat. 

If you have a tractor in a shed plugged in you may have enough heat in the engine area that you would not have a problem with gelling but if you take it outside  the windchill could remove enough heat to gell up just like it removes heat from your body. The other thing is but I don't think Allis engines do it much is they return some warm fuel to the tank but with the wind that would also cool faster.

Some scientist argue that there is no such thing as cold, it is just the absence of heat. Everything would be at absolute zero (no heat in it) if we had no matter around us generating heat.

Hot and cold are really just terms relative to your own perspective. The reality of it is temperature is a matter of energy in sub atomic particles bouncing off one another . The more energy, the faster the subatomic particles move and the warmer the object feels. When two different objects at two different temperatures such as 15 degree air and a warm 180 degree engine block meet one another. The slower moving particles in the air bounce off the faster moving particles of the engine block. Energy gets transferred. The air warms up and the block cools down until they become equal. Think about what happens when you break a racked pool table. The fast moving Q ball knocks the rest of the balls into motion and it almost stops itself. If you were to neglect friction such as inside an atom, They would continue bouncing off one another until they were traveling at the same speed.

I don’t know if I’m adding anything productive to the conversation but there it is. It’s worth what you paid for it.

Right
