You would think at those temperatures he would use a 5W at the maximum if not 0W.
Cold start at -35°F with 10W30 = no oil pressure

A great way to wreck an engine. Amazing it has over 300K miles on it.
Kilometers
I just realized that, still a great way to wreck an engine. And 194K + miles, is still not bad.
Canadians tend to like thicker oil than us Americans it seems.

One year after moving to Iowa I had put Mobil 1 10W30 HM in the 2008 TrailBlazer with the 5.3L V8.
It went down to -28F here one morning and I was worrying about getting to work that morning. It started up without a hitch as if was 48F.

Regarding the third example into the video around minute 4:30
He's running "regular" 10w-30 (presuming he means conventional), AND LUCAS OIL STABILIZER ... then he changes to a "warmed" 5w-40 and adds Seafoam.
So he's got money to waste on additives, but can't afford a decent 0w/5w-30 PAO based lube?
I'm gonna say it out loud .... Idiot!

Right. Too many variables with which to screw things up.

S-10 Blazer 4.3 running 5-30 Castrol GTX IIRC. I had attempted a solo winter camping trip to Mt. Webster/Jackson Crawford Notch, NH. It was frigid, -25 daytime temps. I ended up ditching the loop and reached the summit of Jackson. I attempted to make camp and did but it was -28 to -30 and it didn't take long for me to bail on this one. Amazing how warm you can be when exerting energy.
I made it back to the truck and to this day I've never heard the sound that vehicle made as it struggled to turn over. Soooooo slow! All I could think was that my oil was molasses. Luckily for me it did turn over. I wish I wrote it down or could remember it with accuracy but I don't think that engine reached operating temp until I was through NH and into VT headed south on 91. I was in my early 20's. At 51 now, those temps are a hard pass! -5F At the base is my threshold.

Isn't it an issue about pour point? Wouldn't that be all you need to worry about, to know you do or don't have a brick of frozen honey in your oil pan?
Pour point isn't a very accurate measure of how well an oil will flow in an engine on a cold start. CCS (cranking viscosity) and MRV (pumping viscosity) are better measures, and these are what the W rating of the oil is based on.

With all the brands of high grades synethics in many different weights,I am a bit confused why anyone would possibly want to damage their vehicle like that.
There are people out there with more money than brains I guess.
He owns a '97 Dodge, so I don't think so.
Probably not, but you never know.
Maybe he wants to kill it so he can justify a replacement.
