If LSJR has something to say about oil, I'll listen. I might not agree, but I'll make up my own mind. If a gazillion other youtubers have something to say, I'm likely not interested.

Yes, it's definitely chemical. The assumption was that it was from the oil cooler, but it could also be from a copper-based sealant or some other copper-containing component or compound.
A retired cop knows more about motor oil than LSjr????
A lot of Red Line samples show lead aswell. It's just one of thoise things to be aware off, or just don't do an analysis.
Exactly. His latest video on surface texture and GM's recent issues is a great piece. I am sure there are "experts" here on this forum that will find something wrong with his analysis but it makes a lot of sense to my small mind.
Retired cop vs BA in advertising. It could go either way.
It's just OK
That was my world for 30+ years. Pretty light.
Did he actually mention the actual SB and IS condition of the GM cranks? I may have missed that.
Do you mean you appreciate his "dumbing" down the process so you can understand it?
Ad hominen argument? Is that the best you can do to refute the retired cop positions?
No, you didn't miss it. He only referenced the GM recall and possible issue with the crank finish long enough to use it as clickbait in his title.
I thought the video was interesting. The PhD did most of the talking (assuming he has a PhD since he was referred to as "doctor". It could just be his nickname).

To be fair, I understand that you don't have knowledge of my background. So allow me to enlighten you.
Like most who work in LE and similar (firefighters, etc), we often hold several jobs to supplement our income, develop secondary career paths, etc.
I worked in manufacturing for 32 years alongside my 25 years in LE. Right out of engineering school, I worked at the Ford steering-systems facility in Indy for 16 years (before they closed the plant), where I held several jobs including running maintenance programs for the building, powerhouse and waste treatment plant. I used oil analysis for many applications when it came to gearbox drives, conveyor systems, etc. I earned my boiler operation certification there, as well as my Class III universal refrigeration certification.
Further, after Ford, I worked at Carrier for 16 years. There, I ran the quality lab where I was in charge of all equipment validation and annual certifications. I ran statistical process quality control programs for some of the production lines. I wrote DFMEAs, PFMEAs and DOEs. I was trained and qualified in SixSigma and Shainin Red X root cause analysis.
And I also authored this:

So, yes, this cop knows plenty about statistical analysis and I have a sound footing from which I criticize LSJr's approach to data analysis. He may know more about oil, but I assure you he is not displaying good knowledge of proper data analysis.
See? Another sorta irritating thing, albeit minor, about the guy. He didn't have to do that, but he did for clicks. It's a money show. Speed doesn't know the drawing requirement, I bet.
It was interesting but the doc did not say all that much. I mean how about brushing Ra and Rrms? They just kept holding up those somewhat meaningless topo models.
But I guess this is all too negatory.

2.5ppm is not “much higher” unless you have a loooooong service history and your standard deviation is much lower than 2.5ppm. That’s how statistics work.
