What Our Lubes Look Like On A Cold Winter Start

That's a good demonstration of what different viscosity oil does with temperature and the difference between good oil and a lot of bargain cheap oils but I do have one question, at the oil pan demo in the first vid, why did the tech dude dress like he was in Florida for the first one and then put a heavy coat on for the second one if it was the same temperature?
Must have learned something the first time maybe..

In the first video of the oil weeping out of the engine cam tower bearings while they were cranking the engine, looking sorta pearl colored, where they said it was wax in the oil, to me it looked more like air had been mixed in & the oil was aerated & so cold & viscous that the bubbles couldn't pop.
Anyway it was a good demo of why its important for us to use the specified multi-grade for the coldest temps we expect during the oci. The lower the W number, the better & quicker it'll flow in cold temps. 0W at cold temp is still Way thicker than 30 is at operating temp, so it isn't too thin at cold temps.

Aeration In Our Lubricants
Why You Should Be Measuring Air Contamination in Oil Why we need to be aware of lubricant aeration, as air mixed in doesn't help our lubricants do their thing & cold winter lubes can get so vicious that folding & churning of our lubes can cause serious aeration problems, especially after a cold soak period.
Then we start up, head for the interstate & a high speed run, without warming things up. The video in the first post, of the pearl colored lube in the top end camshaft bearings is a good example. Now imagine what the tranny, differential, power steering fluids are going through without a good warm up before that high speed interstate run, or lugging & tugging that heavy load at high speed in cold weather. Clues us to be mindful to follow the mfgrs specifications for service grade, type & viscosity, for all our vehicle lubes, as they're formulated to address & minimize these problems, but being aware & visualizing whats going on in various parts of the vehicle, sure can make it easier on our equipment, which it sure would appreciate, if we'd adjust our drive cycle accordingly.

BUMP: Cold Weather Reminder !!!!
If you live in cold country, have a look in post #1 at these Two videos, part 1 & 2 I first posted back in 2014, to see what your cold temp engine, differential, tranny, power steering lubes & grease might look like where your vehicle spends winter.
Make sure your using the right viscosity & service grade lubes for your cold country service this winter.
I'm in the process of performing the Scheduled Maintenance 90K mile service on my 99 Ranger, so its time for the engine, differential, tranny & power steering fluids to be replaced, so I'll be mindful to abide by Fords specification call outs & use top quality fluids that say they meet or exceed Fords specifications for my area. Yup, at times it gets as cold here in the mountains of SW Va as it does up in New England, just doesn't last as long but that's of little consequence if that puppy is so cold its frozen to the ground, or so stiff things don't like to move. This puppy sits outside 24 / 7, so I don't rush things when I wake it up & ask it to go.
How ready for Winter are your rides???

Fascinating videos---first time I'm seeing them though. None the less they do illustrate how our oil and other lubricants affect engine life and performance. I have to chuckle just a bit as I've begun using an engine pre-lube system on my 5.4 gasser---that's been bashed a few times as needless and a waste of time & money. In both cold and warmer temps having oil with sufficient fluidity available quickly should be a benefit---I'm weighing a $350 cost to install against another reman'd engine to the tune of $4500 or so---seems a good gamble huh?
Anyway thanks for sharing these PawPaw---reps sent!
