BORPower additive?

2) they're interested in 'SEVERE' conditions in which 'high-point' might be achieved, not in 'NORMAL' operation.
3) in 'NORMAL' operation, at least a nanolayer of oil would be separating metal surfaces, boundary lubrication would be at play, with zero metal-to metal contact.
4) the 75W-90 gear oil testing is not germane to 'engine oils', as transmissions, transaxles, transfer cases, rear axle/differentials etc., are not subjected to the same conditions as are experienced within internal combustion engines.
5) we'll have a discussion in the future about 'how it worked so well' for you.

Polyalphaolefin 4 (PAO 4) is a synthetic oil used as a base stock and viscosity builder in Engine gear and motor oils etc.

So:
An admission that it works very well with the 2 main additives in most engine oils.

And we are now on to:
Yes but what about the other stuff?
Is this correct?

I NB that people mix different brands of engine oil all the time, adding a can of whatever the gas station has on hand to the engine when the oil's low.
It would seem then that, while ill advised, there are no disastrous effects from this age old practice.

In fact; one might go so far as to say that the oil makers avoid using substances likely to clash disastrously with their counterparts.
Including Borate Esters, that react with the water in engine oil, to form BA.
Can we not..?

So why don't YOU list all the various:

• Rust and corrosion inhibitors (BA does this)
• Detergents
• Friction modifiers (BA does this)
• Antiwear agents (BA does this)
• Viscosity index improvers
• Pour point depressants
• Foam depressants
• Oxidation inhibitors

used in engine oils, along with their chemical reactions with the weak Lewis Acid; Boric Acid (reaction products) at the temperatures and pressures found in engines.

Remember; unlike you, I tested BA and I say; it works incredibly well.
Therefore:
It's up to YOU to find proof that I am either a liar or delusional.
(That's another question you have studiously avoided answering btw, although it is implied)

2) is the 'alumina' from the alumina 'pin', from the 1990 ASTM, volume 3.02, Section 3, pps 391-395 Re: rotating-disc-steel / alumina hemispherical-tipped pin @ 3mm /second @ 22-25-degrees C ?

3) from the Roach Criteria for acceptable engine wearing surfaces, opposing a steel surface:
-germanium
-silver
-cadmium
-indium
-tin
-antimony
-thallium
-lead
-bismuth
-I'm not seeing 'alumina'

You want to see some alumina wearing surfaces:
Have a look at the most all the pistons in modern vehicle engines.
They are exposed to oxygen you know.





Perhaps you are also having trouble Iron Oxide despite the fact that is the base metal in just about every other wearing surface in an engine?

So Roach better take another look if Roach wants anyone here to take him seriously.

And yes; I dissolved BA in boiling water before adding it to engines.
One must assume that said emulsion got water and BA(aq) in contact with wearing surfaces to more or less the same extent.
That is after all one of your issues with my BA treatment.
Or isnt it?
It's hard to decide when you change your arguments all the time.

Tell you what:
YOU go off and prove that BA DOES NOT react with the alloys and their oxides in your list
despite
said reactions being one of the issues you had with all this in the 1st place..!

3) From then on, unless the engine was neglected or abused, at least boundary region lubrication would be separating opposing surfaces from actual contact, by definition.
.

Ah...
So... once engines are run in, they just stop wearing completely and last for ever?
Is that what you're telling us?

5) And regardless of what the oil's anti-wear additive capabilities are, all the other protective additives will technically be 'gone' by 7,500-miles of 'normal' driving, or whatever interval is

Or...perhaps the detergents and dispersants simply had nothing to do thx to the BA..?
As you don't actually know due to zero experience with BA in an engine;
It's up to you to prove this opinion of yours.
