LSJR Calls Out YouTube AI-generated Video Referencing Him

[mojoe]

For those of us that generally avoid Youtube, what is the basis for the "wear protection" data?

You don't trust LSJR, do you?

Some great info here. I especially liked the data on shear and the importance of staying in grade. Having headroom was even mentioned which is also talked about around here and I agree with 100%.

Now as far as the UOA wear data. I’ve read several official wear studies posted here over the years. Never saw one that has a lower viscosity having less wear. These engines were torn down and measured. Not sure that used oil analysis are the best tool to determine the wear difference between viscosity’s. If it were, the official studies could have saved a bunch of time and money.

I will give Lake credit as he did mention the differences were just noise. Now I’m still waiting for data to backup his oil filter claims….

LSJR measures wear by looking at wear metals in UOA per 1000 miles.

Not confusing at all to me. Pretty clear and straightforward. By all means, use what you like, but don't automatically expect a higher viscosity to provide better wear protection, because often, it does not.

Really? When does it not? Must be the new physics I hear so much about on here. And how are you measuring this wear?

You say “often” so it clearly isn’t an isolated case.

I’ll go one more and say that I’ve never seen an official comparative wear study that used uncontrolled $30 spectrographic analyses.

And to your second point, it’s not the best tool. In fact, it’s not the tool at all. If the differences are just noise then they are just that, noise, and nothing else.

So LSJR wasn’t enough, now I should watch him and AI? Can someone tie us to a tree and smother us with honey?

 

[kschachn]

You don't trust LSJR, do you?

Some of us just don’t fall for his Kool-Aid in every sip.

Oooh I’m a hater.

I don't trust used oil analysis for comparative oil performance analysis, because that's beyond the scope of the tool's use. That's why I asked.

I don't get what the big deal is with YT or AI? If it's AI, don't watch it. Always look at the source. Same with any platform. X is full of garbage, but you can still follow legit people.

No kidding.

Which you can't do comparatively.

If the differences are noise then by definition, there are no differences. Which is what one should expect to see with used oil analysis on healthy equipment with an oil of suitable viscosity and carrying the appropriate specification for the application.

used oil analysis are good to monitor oxidation and viscosity changes. TiGeo's used oil analysis were valuable IMO. People tend to like used oil analysis when they're favorable to their brand. In his series, it was clear HPL was holding its viscosity better.

 

[tolian21]

I am still curious what evidence he has when 0w-20 protects better than 0w-30 ?

And any such analysis would have huge error bars that would swamp the relatively tiny differences between the oils.

Yep, they are good for highlighting material differences in product and giving an overall health grade for the equipment. It's when we start trying to compare single digit variances in elements that are being measured in parts per million that things sometimes get a bit silly, and apparently, he said it himself, that it's just noise, which is what one should reasonably expect.

And yes, properly trended used oil analysis CAN provide valuable insight into component failure. Not always, but it's one of the intended uses and they are valuable in that regard. They often can't catch rapid onset failure, but something slowly starting to wear unusually can often be picked-up.

I guess I'm a simpleton who loves kool-aid. Thanks.

Think of used oil analysis as a cheap digital bathroom scale. It has a decimal place for fractions of a lb, but it only actually gives you half pounds, it's 5 or 0. Now pretend you are trying to determine if Winchester or Federal puts more grains of powder in their shells by weighing full boxes of ammo on this bathroom scale. The resolution just isn't there, and you are making an inference, because you have no idea where the weight comes from.

There are a lot of these AI generated channels that are parodying well respected YouTubers. I'm not sure what the long game is.

The long game is money, if these AI producers saw no financial benefit, they would not waste their time. I personally wish YouTube would supply an AI on/off check box so you could tell the difference and had a choice.

Not a bad analogy
