N B that I did not use this product:
It's expensive as hell for some finely ground Boric Acid and a surfactant.
Finely ground because the finer the powder; the better it worked in tests, but can you mill it finer than single molecules as is the case when it's dissolved in water..?
IMHO being salesmen; they know that most all people will run screaming at the crazy idiot/idea of adding water to engine oil.
So they decided a longer 'kick in' time that relies on the water that naturally ends up in engine oil was the better route.
Me, being a dumbass and not caring a damn about salesmanship, get/got it to kick in in about 10 km.
With better results than they get, thx to the unbeatable fineness that comes from single molecules as is the case when dissolved in the very stuff that makes BA work as a solid lubricant in the 1st place! IMHO. 
We cannot avoid the water that ends up in engine oil, so why not turn that to an advantage..!?

1) The Herguth Lab. test I looked at involved heating two lubricant samples in an oven , at 650-F, for 2.5-hours, then examining them.
2) Synthetic motor oil is stable at 700-F, with or without 'boron'.
3) An engines upper cylinder area is about 600-F.
4) Piston rings run about 400-F.
5) About 30% of mineral oil-based motor oils will boil away at 400-F.
6) Mineral oil-based motor oils volatizes above 475-F, turning into varnish, tar, and sludge, destroying the oils viscosity. Carbon from the oxidized oil can freeze the piston rings in their lands, leading to loss of compression, blowby, and water vapor entering the crankcase/ valvetrain region.
--------------------------------------------------------------------------------------
7) Being 'finely-ground' was a necessity according to Erdemir. Anything 'larger' ( heavier ) and it would settle out of the oil under gravitational acceleration. And it needs to be smaller than the pore size of the oil filter, otherwise they'd be caught and lost.
--------------------------------------------------------------------------------------
8) Boric acid is 100% soluble in water, so you get a basic 'solution' of it, the BO-3 (3-) ions acting as bases to remove protons from the water ( hydrolysis ).
9) Boric acid is not soluble in oil and can cause corrosion in the engine due to its hydrolytic instability around 'moisture.' ( in 1991, Erdemir thought his boric acid oil would require another two-years, undergoing batteries of tests to prove out environmental and safety issues inside engines ).
Peeler's US Patent # 3,313,727, for the inclusion of a hydrated alkali metal borate, water, & emulsifier in lubricants led to gear and bearing failures when tested ( in the presence of moisture, the borate crystalized out of the oil and formed hard granules causing severe noise and damage, thereby decreasing the EP function it was intended for ).
John H. Adams, of Chevron Research and Technology, in his US Patent# 3,912,644A, introduced potassium borate into oil, partially neutralizing it with the acidic anion of phosphoric acid, sulfuric acid, and / or nitric acid, and a mixture of lipophilic dispersants, to create a more stable EP additive.
-------------------------------------------------------------------------------------
10) Engine 'moisture' evaporates in about 30-minutes once an engine reaches operating temperature. A 'water-boric acid' solute in motor oil would be 'gone' under these circumstances, leaving 'large', 'heavy', boric acid molecules in the oil ( maybe in the bottom of the pan ? ), instead of 'light', 'engineered', colloidal, sub-nm particles, as Erdemir ultimately arrived at in 1991. It leaves questions about the boric oxide plating and platelets.
--------------------------------------------------------------------------------------
11) MotorSilk asks us to 'wait' 2,000-miles, or 60-days of driving before expecting an 'experience' attributed to the product. They tested for 196-hours, covering 6,495-miles. ( Erdemir never 'finished' the technology and tested it, so we have no benefit from that ).
--------------------------------------------------------------------------------------
12) For road tests, you would be required to drive 66.3-km, at 88.5-km/h, continuously, 'before' beginning your test. It's a global standard.
Anything you've experienced at 10-km would be embedded within the 'noise' of non thermal-equilibrium performance of the test vehicle.
-------------------------------------------------------------------------------------
13) If you have to bank on the attributes of boron's 'solid lubrication' you've lost your engine.
--------------------------------------------------------------------------------------
14) If your driving goal is to operate the car in such a way that the engine never warms up, then we have a talking point.
