Normal engines have tighter tolerances?

You sure can, Takes a small amount of thinkingUnless it's on the top of the engine...
This is also with a fairly high rpm LS engine with aluminum rods that's overbuilt with wide clearances to handle a lot of boost. The bearing clearance is much more inline with the 20W-50 than the 5W-20 which is the contributing factor for the higher wear and windage from the 5W-20. If the engine had steel rods with .001" tighter clearance, it wouldn't have made a difference, but then you're pushing different limits with the cold WOT runs on the 20W-50. This is why I don't like comparisons of drastic different viscosities like this as the engine is always going to favor one over the other depending on how it's built. I would much rather see two 5W-30 oils with similar KV100 but 0.5 cP difference in HTHS (say 3.1 vs 3.6) in an engine meant for a 30 grade oil.
It's worth noting that despite the engine not being built for the 20 grade oil and dealing with excessive windage, the 20 grade still made more power with less friction. This was also a syn-blend oil that's majority group I.
The video also gave a shout out to PF. Why would a guy like Mr. Speed with oil credentials give a shout out to a supposed internet oil hack? Since the video did not use sanctioned methods for testing, is the video by Mr. Speed on the same category as PF? Or do these videos give us some nuggets of information?

I wondered why he gave PF a bit of praise too, since there is virtually no science in PF videos but a whole lot of speculation
Walk me through it b/c I clearly am not following this. Beyond soaking the filter, any free-oil will simply run out as I try to flip it over onto the oil filter housing. Or maybe you mean install the filter onto the housing first then put the cover over/screw on? Unnecessary either way.

Do you have cartridge or spin on?
A cartridge...I answered the question related to cartridge filters....
It settles the thick vs thin debate on this particular heavily modified LS race engine - absolutely.
However they say multiple times this engine is very different from the average modern mass produced engine. Making a blanket declaration like that is not telling the whole story.
Oh IBL for sure now.
And yet, they are both terrible to pre-fill in the horizontal position, for the same reason, because they're really messy. The fact that one is 25-50% less terrible (you can still pre-soak the filter element in a cartridge if you choose) as the oil pours out the side and down your arm gives little consolation that one is somehow superior to the other. They are both terrible and I'm not going to get into arguing degrees of terrible - it's simply enough that I will not pre-fill either for the same reason.
Stick around b/c I am about to learn how to pre-fill a cartridge filter that is in the vertical position on top of the engine. Very much looking forward to this. I guess I could install the filter on the housing, exposed w/no case, then pour oil all over like hot-fudge on a sundae, then put the cover on?
Correct. I do not know. Which is why I requested that Lake run the test with a 4 cylinder.
Cool video.
I definitely will not be going from 0W20 to 20W50 in my mass produced four cylinder commuters anytime soon. Might start pre filing filters now though. That water and blip was an interesting anomaly.

Oh come on now, where's your BITOG team-spirt? 20W50 HD diesel oil in that econo 4 banger will help it last forevvverrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr!
