cold oil flow

Nice test and great visual impact of what the different oil weights will actually pour like in cold weather. Makes you think what's in your vehicles

Knew a guy that had an old Chevy panel truck with a 6 cylinder in it. It burned so much oil he ran straight 50 weight oil in it. He tried to pour some in the motor one day and it was bitter cold out (-45F). Well it just would not pour. He cut the whole top off the can and it would not even move when held upside down.

We took it inside and put it by the heater at work and slowly it thawed out. My old Dodge started that day not plugged in or rather the breaker had tripped because everyone had to have interior warmers plugged in. With 10-30 oil the lifters clattered something terrible, I thought it was going to come apart. My foremans K car (also plugged into a tripped breaker) tossed a rod out the side of the block because he reved the motor once it started, he said he always did that because it helped to circulate the oil faster. Who ever told him that cost him a motor.

10-30 was the norm back then. 10-30 would hardly pour in the cold. At -40 it took seconds before the oil pressure gauge would move off 0. It was why I switched to 5-30 for the winter months!

Just a note on what you say in the video. You mention the wind chill, can be good to know but I hope that you know that is the effect of the wind on the human skin and the wind will not affect the temperature of the oil.

Here is a similar video. Not sure I would be able to hold anything bare hands at -50C but cool nonetheless.

Exactly, and why these tests, just like the "wear" test machine mean nothing most of the time.

If you want real answers/info on what is good and what isn't, nothing is more concrete, fool proof, true than good old UOA's and VOA's, just like what is posted at bob is the oil guy .com
