I wonder how this pressure-activation works and have been of the thought that Ti is basically a solid lubricant that provides higher MOFT.
Appreciate if you care to provide link(s) on the diamond thing and its mechanism ?

Reduces friction by %20 ...

Let assume that friction was 0 to begin with. Not realistic but for the sake of the argument ...
Reduce that by %20 and you get %0 reduction. Meaning no reduction!

in a more realistic case, reducing a very low number and/or a relatively insignificant number by %20, will result in an insignificant reduction! Meaning marketing at work shocked2

Not saying the oil is bad. I have 2x5 qt. of intelligent molecules in my garage but you gotta know the real numbers and do the math grin2

Diamond anvil cell is a device that uses a gasket around two sharp diamond tips (anvils) to apply pressure to the material inside so that the material's physical properties under gigapascal pressures can be studied. Such pressures can be experienced in the camshaft etc.

https://en.wikipedia.org/wiki/Diamond_anvil_cell

[Linked Image from upload.wikimedia.org]

Here the electromagnetic radiation is the X-rays originating from the synchrotron mentioned in the article, which can generate a very "bright" (high-intensity) X-ray. They can then use various techniques to study the structural changes of the material (Castrol oil in this case) under varying pressures in the gigapascal range.

This is the experimental device they used. However, they didn't provide any reference to a publication and I couldn't find a publication. Therefore, this could be an internal study and we are in dark as to what the mechanism of action is -- we don't know what kind of structural phase transition happens, let alone know how it happens.

Such structural phase transitions sometimes can be modeled using ab initio density functional theory (DFT) but that doesn't always work, especially if electron - electron interactions in the material are too strong, which results in complicated quantum mechanics that no one really knows how to approximate and solve.

Doesn't seem insignificant to me when all that's separating two moving parts is a 1 micron thick film of oil, as can be found in places in the engine. In those boundary areas I'll take any reduction in friction from an EP additive I can get...

I believe the Ti additive interacts with the metal (not the oil) at these high pressure/temperatures area to form a sacrificial layer between surface asperities, thereby reducing friction.

Typically this contact in surface asperities (boundary area) occurs when the MOFT has broken down. In effect, the EP additive is your last defense against metal to metal contact.

(Gokhan/Mola???)

It’s an expensive material so figured the amount in a jug fits on the pointed end of a stick pin

You read the part where the R&D was not done with the exact amount you get in a Walmart jug in Florida

Thanks Gokhan, think you're right.

Pretty cool you were working in that area too.

This is science for sure.

Agree on Castrol's website. It's always been pretty bad. Not as bad as trying to find one of their PDSs though.

Is there a thing as non-performance-robbing friction?

And based on that statement, it sounds like Ms. Rebecca Yates has her Ph.D. in marketing, not science. Edit: Went searching on LinkedIn. Rebecca Yates, "Procurement Manager" for BP, has a blank, empty profile other than the supposed position. Since you can't find anything other than Castrol press releases with her, it's almost like she's a figment of their marketing team's imagination?
