Holy *&*^%^^!!
 
-18 F in Swansey, NH (Just south of Keene).
My Windstar cranked just fine with Motorcraft 5w20.
This was after sitting in the cold all night.

That is a must in cold weather. If you recirculate the cabin air, you add moisture as the air warm up. Warmer air can hold more moisture, so the windows fog/ice up inside the car. By drawing in the cold, dry outside air, you keep the humidity level low, reducing the fog/ice.

The coldest was -39F in the later 1990's, it was in High School, and I was working late at night as a stocker for a store. Car was a 1988 Plymouth Reliant, with the 2.5. It started after sitting 7 hours in the cold, I had to jump 8 other employees that night. It was so cold that my jumper cables would not flex, it took two people to uncoil them. Coldest recently was -27F two winters ago.


I don't buy that for a minute! You don't add moisture just because the air temperature heats up - you add moisture from your breath! Warm air can hold more moisture at 100% relative humidity as your graph clearly shows - so if its colder, the chance of fogging windows increases! That's why you see fog and dew in the early morning when the temp is coldest and near the dew/frost point. You keep it off recirculate and crank the heater/defroster so the increased moisture from your breathing goes out of the cabin of the vehicle and the interior surfaces, to include glass, warm up past the dew/frost point and moisture won't condense/freeze on them.


Well, that is what I was trying to say. The added moisture is from you, snow melting off your boots/shoes, and many other ways. As the air temp increases, it can hold more moisture, that moisture than condenses on the cold glass. So in a way, you said what I was trying to say, so thanks!

My old powerstroke was -40F after sitting all night
Chevy and Nissan -45F after sitting all night

Both times were not including the slight breeze either

In the Ranger, about 5F. Not too cold but this was in Northern AZ, coldest this truck will usually see.

Had PP in the sump, sounded fine. Idled high for a bit but no odd noises.
 
-29 F according to the bank clock in the neighborhood, Madison, Wisconsin. '86 Golf, probably 5w-30 Mobil 1. Had an oil pan heater and a 6 amp trickle charger going all night. Started right up, like it was +30. Only problem, when I released the clutch, in NEUTRAL, the whole car shook like a cement mixer. Guess the trans lube thickens up a bit at low temps. Not to mention the oil in the struts. (Creak, groan)

I would love to see a slow motion video of the inside of a transmission being rudely awakened from a -29F sleep.
 
-42F actual temp.

Went out Ice fishing in northern Minnesota.

The Bias Ply tires were hard as rocks.
 
-27F actual outdoor temperature but the car was in my unheated garage. Started right up, no issues...other then the heater fan complained a bit..

When I started my Corolla at -15F a few years back, the rpms went from about 1500 to about 400 when I let the clutch out in neutral - almost stalled - I had to keep the clutch pedal in for a few minutes before it would idle in neutral. 75w-90 at those temps has the viscosity of bread dough.
 
-17F in Northeast PA. back in 1996.Was an automatic 1983 Toyota Corolla Station Wagon. 10w-30 dino oil. When my heater finally got hot it cracked my rearview mirror. great car never got stuck, had 177,000 on it.
