There is nothing there showing how the product works, and there are plenty of chemisties that will provide the same results that do not cost $25 an ounce. Proven chemistries that build much thicker layers on the surface and are just as much attached.
I don't know if you are using these chemistries in your oil or not, but it would appear that an electron microscope is required to verify that these nano-diamonds are present in the oil. They certainly should not show up on any standard oil analysis. How very convenient.
Are my technical points wrong? You did not address them.
