True. However, it will cool ONLY to the ambient temperature. The "wind chill" only effects exposed skin. The engine will NOT cool to the -50 (or whatever) "wind chill".

:h I had thought for years that wind chill did indeed affect fluids in the vehicle, but you folks had convinced me otherwise over the years here on the forum.

BUT, and this is a big BUT, my thinking has changed somewhat again.

Seems my current vehicle has an oil temperature gauge (2011 Ford F350 King Ranch with 6.7L diesel).

The oil temperature gauge has consistently shown a temperature below that of the outside ambient temperature on any given day that I start the vehicle. My vehicle sits outside, and is NOT garaged, thereby exposing it to all elements.

Now this is interesting to me, but not yet of use more than anecdotal at the moment. This is because I have not yet checked these oil temperature readings versus the current wind chill readings for my area.

However, as I said, the consistent below ambient temperature readings I am getting surely has me curious. Also, these temperatures are shown for the oil without the vehicle being plugged in to its factory block heater.

My BL drives a big Pete w/Cummins and he was up in St. Albans, VT where it was -15 and he had to use a lot of Diesel 911 to get back to Albany, NY.

Absolutely correct. You can speed up the effect of cold temps by adding in wind, but the temp of a piece of metal will never go lower then the air temperature that surrounds it.

I use the power service also, no problems in the -35 to -50 wind chills Monday and Tuesday.

Fired up the 06 Duramx today after sitting 15 days with a few -25's iin there.Put 30 miles on in -14 temps ran great. OH yeah I do use the Diesel Kleen White stuff.

I started mine this afternoon at a -6 after sitting for 3 days. Its not plugged in and hit right off with quick oil pressure and very little noise. I expect the '13 Navistar school bus I drive will not start easily Wed. morning after sitting since 20 Dec. and plugged in.

I've had our 2003 since new and never needed to add anything. Started this morning, about -15. Started this afternoon after work -18. It'll start tomorrow AM, about -20.
