That is some interesting stuff! I admit I have become a bit cynical about engine additives, but this nanotechnology is fascinating.
I used to have an old Suburban with a 350 that burned a lot of oil. At the time, I tried Restore. Restore has CSL, which is just a fancy way of saying copper, silver, and lead are the main ingredients. It never seemed to do much, but I never performed any compression tests, either... This was before I became a car guy; all I cared about the the oil consumption.
Since then, I have wondered if those additives are wasted, caught by the filter. It seems to me that large particles would be captured, and smaller ones would not be able to to any appreciable "repair". I just don't know enough about it...
In the case of CSL in Restore each particle is spherical in shape and average less than ten microns in diameter which allows them to pass through the oil filter and circulate along with the motor oil.
