The comments on this vid are priceless….reminds me of teenage groupies.

yes but over filling was defined here as the crank hitting the oil in the sump and frothing it up. That's a severe over fill. It would lead to extra vibrations aswell.

I watched it …
seems like a short test to reach any real conclusions …

Agree wholeheartedly. There’s a lot of naysayers against Lake but I enjoy his videos. They are better than 99% of the automotive content on YouTube.
like what?
right, what yt video isnt?
LSJR makes videos talking about what he loves and does for a living and doesn’t try to be anything other than himself from what I can tell. No characters or exaggerated personas. He never does click bait titles like Scotty Kilmer for example. And seems to have a good network of people wiling to work with him which says a lot IMO. Some of ya’ll should lighten up. Or maybe even start up your own YT channel about oil and lead the way.
I generally agree, he's a cut above. But he is way off the mark if he even mentions the word "science" and "conclusion" in the same sentence within any video he has made so far.
Post if the year and 100% truth!
Agreed. My wife and I are both in different fields of science and have had that same conversation about how people present data many times. Some act as though this is the truth and the end of all discussion cause “science” while presenting info. We don’t agree with it. In that regard the listener has to ignore the topography of the speaker and just focus on the findings. Which can be challenging at times.
I take it you left a more critical one?
Lake being so knowledgeable is why this vid is so misleading. I’ve personally started threads at least 2 or 3 times here with Lake vids I thought presented invaluable information. This vid is not one of them because he should be up front that:
Using wear alone does not conclude an oil is good or bad or comparable to another.
The UOA wear numbers of each oil are all within the margin of error of each other. In fact a UOA is not the right tool to compare oils based on wear.

I usually leave one. Sometimes I'll say something like "the folks over on BITOG will lose their minds when they see this"I saw yours

He could do his own taxi testing for example - whilst a few of them are still around - that was the standard in proof of performance for years … the short dyno is what I question
I saw yours
He's something else...haha
It would have been interesting if valvoline had done UOA’s at each oci on those side by side 500k mile run engines. Then measured everything after tear down at the end to compare data. That test took years if I remember correctly.
As much as this group likes to say you can’t compare oils this way has anyone shown a series of identical in engine tests produce inconsistent results? He’s got an engine hooked up to a dyno in a lab, that’s a pretty great environment for repeatability.
Now as the experimenter it’s on him to show this but I’d also ask what evidence to the contrary do we have to be so certain you can’t do this?
Looking at the reports he showed the difference in wear metals 2 hr - 0 hr was
Amsoil: 24 ppm
Super tech: 20 ppm
Royal Purple: 20 ppm
NAPA: 12 ppm
If he ran that engine a bunch of times with a fresh batch of the same oil and found the wear metals only varied by a few ppm and if he took multiple samples from the same run and sent them to the lab and found those results only varied by a few ppm, a difference of 12 ppm would start to look pretty significant.
Personally I’d also like to see going from a known low wear to a high wear oil and then back to the low wear oil to show the wear history isn’t a factor, but again with that kind of setup you could get a handle on that.
