LSJr- Do “Film Strength” Testers Tell The TRUTH?

[fantastic]

LSJr digs into what a basic lubricity tester was created for & where it excel & does not excel by testing motor oil and gear oil. Shows that It only measures a certain type of wear & calls out a "famous" Youtoober using it to "test" oil. It does not correlate or give the whole picture of actual wear dynamics inside an engine. There is no API testing standard that uses these types of tools for motor oil. Oil manufacturers etc spend millions of dollars to test oil & this cheap tool does not suffice.

LSJr uses Castrol API SJ Classic 20w-50, Castrol API SP 20w-50, GL-5 Valvoline, & a High Performance Lubricants gear oil (Specially made for his dad's race car) on a lubricity tester. Put the same oils on a test using the TE77 Recipricating Rig. Where the gear lube did well was on the lubricity tester but the same can't be said on the Recipricating rig that shows the motor oil & the Castrol API SP having lower wear (vs the Classic SJ).

So in short, Don't rely on these lubricity testers to show which oil performs "best" in your engine. There are different forces going on in an engine that a lubricity tester can't & does not show.

Did the other thread about this get removed?

Did the other thread about this get removed?

Yes, because it didn’t have any comments added in the original post with the video, and that’s a violation of copyright rules

Think we know where this ends without watching …

Glad this is back. 10/10. Rat540 is quaking in his boots watching this. Good shout out to PF and how LSJR likes some of his testing. I dug the HPL stock car diff oil performance - I know that was a big thing for HPL and their NASCAR race teams...next dif/bevel change I'm probably switching to HPL vs. the Redline I use now.

He said it wasn't intended to "call out" (as in a negative which your comment implies to me at least) that YT'er, he also mentioned how some of that YT'ers tests he quite likes.

I wish he put some shampoo on it.

Also - note the VW EA888.3 engine at 0:40.

I doubt it. Generally someone as clueless, ignorant and uninformed as that tends to soldier on regardless of anything that might be contrary to the empire of crap they’ve built.

He’s also belligerent and hostile which reinforces the ignorance.

Not just any - it was dandruff shampoo with zinc

You can read between the lines. Look at the avatar and you didn't see the original title of the video before he changed it. It was calling out in a pretty direct way to those types of YT "testers" IMO. I like both channels personally.

Lol I commented that he should have done a test with head and shoulders and he replied maybe next time.

I was interested in the ring wear test showing that the Gear lube did worse that the motor oil.

Can any one explain why? I would assume it would do better.

 

[Exhaustgases]

The test is valid to show EP qualities of a lube.

Rat540? Did you mean 540Rat? Unlike many that think they are experts, he is an engineer with some special patents.
Only reason folks like him get a bad reputation is because he says things that others don't like to hear, and goes against some belief system.

New or old gear lube? I would think the new stuff has most of the quality EP additives removed from what was allowed in the older times.

This is due to differences in load determining the activation of the additives. Anti-wear additives react directly to metal surfaces to form hard barriers that prevent contact. This is mostly in sliding/abrasive wear situations. Extreme pressure additives act more like the shock absorbers on your car. They tend to be more load reactive where as anti-wear additives are more friction/heat reactive. With the exception of high end solid roller race engines, EP additives are of little benefit to engines. This includes the gimmick oil supplements containing solid particle EP additives of graphites and borates. The same for gears where anti-wear additives lack the load carrying capacity, especially at low temperature.

Anti-wear = high speed, low load
Extreme pressure = low speed, high load

Yes it is valid for gear oil, but again only when performed in accordance with a standardized test procedure and then when the results are analyzed properly.

He gets a bad reputation because if he really is an engineer then he gives the profession a bad name. He knows nothing about proper test methodology.

I do something backwards from others in my Jeep. It’s a DD - that does not tow. I run ASG 80W90 in the rear and that keeps temp down at low load/highway speed - but 140 in front for long sand runs where the front tires cut the virgin sand …
I think a front Dana “pumps” oil to the R/P/bearing interface better than the rear …

You’re saying that more modern gear lubes have decreased amounts of EP additives?

His commentary on the tester is pretty ironic and self-incriminating, because his commentary in many of his other videos doesn’t correlate to or give the whole picture about oil inside the engine, either.

If you drank a shot glass of salt water every time there was an exaggeration in his videos, you’d be dead from dehydration before the end of this sentence, and your eyeballs would pop out of your head from the swelling. Which is what I feel is going to happen when I hear his voice!
