Wind chill -50

[DonFitzwater]

Food for thought!!!


Why shouldn’t I just use Diesel Fuel No. 1?
While Diesel Fuel No. 1 has an advantage in low temperature conditions, there are some disadvantages, as well. The energy content of Diesel Fuel No. 1 is about 95% that of Diesel Fuel No. 2 and will provide a correspondingly lower fuel economy.

Diesel Fuel No. 1 is also lower in viscosity and provides less lubrication for the fuel pump and fuel distributor.



I run Pump Diesel in winter, so I have been using this on all of our equipment

Mechanic at the Case IH Dealer suggested it, seems to make the Dodge fire up better and smoother than it did with other anti-gel that I was using. And is ok to use with the afterburner exhausts on the Audi and Case IH

Once I stopped running additives, I've stopped having random injector failures...........not sure if they are related or not, just my experience. No #2 is available here and I can't remember the last time I saw a pump for it...........maybe they offer it down in anchorage?

The above is the only additive that I run in the two that have the exhaust filter on them, and even then both dealers said not to over do the additive, On everything else I use the Amalgamated Winter blend for anti gel. So far so good!!

Wind chill is a measure of the RATE that an object cools (heat is being removed) if there is air movement around the object.

IE. If you have a 140*cup of coffee and it is too hot to drink what do you do? You blow on it. What is happening, the increased air flow on the coffee causes the hot liquid to cool off more rapidly. If your breath is 96* the coffee will never cool below 96* (forgetting evaporation).
Going back to the OP’s -50* wind chill factor. If the air temperature is -10* degrees the object will never be below -10*degrees. The RATE that the heat is being removed from the object is the same as if the object is in -50* still air.

Remember evaporation removes heat! In addition to wind speed, wind chill is also dependant on moisture on the object being cooled. Animals (humans) have moisture on their skin, which increases the rate that heat is being removed, which is why you have to be very careful about frostbite when the wind is blowing across your unprotected skin.

Point Two

A “fully” charged battery has had the Lead Sulphate plates changed more into Lead, increasing the amount of Sulfuric Acid in the battery water which lowers the freezing point of the liquid. In a “dead” battery the Sulfuric Acid has moved into the lead changing it more into Lead Sulphate which lowers the Acid concentration (making it more like water) increasing the freezing temperature. That is why the best way to check the % charge of a Battery is to use a Hydrometer (a digital Volt meter is a close 2nd) which measures the specific gravity of the battery acid. More Acid= charged Batt. less Acid=dead Batt.

best description yet!

I know a '97 Cummins with functional grid heaters and 2 good interstate batteries didn't start at -25° F. The truck was only shut off for 6 hours. The truck didn't have synthetic oil in it however. It ended up costing me $85 to have a big truck come charge the batteries for 45 minutes until it would jump off.
