LSjr Tests VOA of 20 yr old Valvoline & 40 yr old Mobil 1 Oil. HPL tests Anti-Foam in Gear Oil.

It also used water white base oils.

Tom, you are truly a wealth of knowledge. Really appreciate your contributions!

And this does not apply to Mobil 1 in a hermetically sealed steel can - the oxidation numbers there are likely due to the ester content.

Thank you! This was what I suspected.

As I pretty clearly stated I have nothing against Lake Speed Jr or his dad and family. I enjoy his videos. He asks some cool questions actually. It is the same with anything. Retain the right to critical thought.

And I get it - he has to condense and reduce or every video would be even longer. But he should more often say when and why he is doing so. I think he would be a better tribologist for it. As in mentioning other possibilities than his seemingly hard conclusions.

I’m also sure he’s a very nice guy and knowledgeable. But just like with any other YouTube content creator it’s all about views/sales and marketing. The presented information may or may not be good.

@High Performance Lubricants I would be grateful if you would run a foam test on Rotella T6 5W40 and your equivalent HDEO. This might shed some light on the Rotella comments.

While more views are always a good thing, he's not doing this just for views. He's passionate about oil and friction and enjoys substantial discussion. Hanging out with him in person, he will talk your ear off. lol The main reason he started Speediagnostix was to have one on one discussion with people over their oil analysis and go beyond the benighted comments of a rookie lab tech.

Have they tested delvac 1 5w40 in the foam test?

Thank you. I missed this.

Remarkable.

Does all the HPL oil have that same lack of foaming? Even their cheapest PCMO?

Just to clarify, the Rotella was fairly recent production and not some 10 year old jug from the corner in the garage?

Yes, recent production. CK-4

Yes.

 

[Pablo]

Yes.

As should any motor oil claiming to meet this test.

Not a particularly high barrier

Holly Swift! I have never seen anything like this. The base oil selection in that HPL must be exquisite. That's not just the anti-foaming chemistry alone, that's the entire formulation.

I hope you're having a great day! I was wondering if you might have some data available on how AMSOIL Signature Series performs in the foam test, specifically for the 0W-20 and 5W-30 viscosities. I'm very interested in learning more about these products. Thank you so much for your help and time in advance.

The tricky part is balancing the chemistry for foam prevention and aeration control as they tend to work against each other. Decreasing one can increase the other. When you manage to control both, you've got something.

ASTM D892. Pass and pass. I don't have pretty pictures of all oils and lubricants in the foam tester.

Thanks. Feel the same way about you.
