No, it will get squeezed into nano surface asperities under high pressure and form a coating on longterm usage and increase surface area of contacting metal surface thus greatly improving anti wear and load carrying properties at nano scale, which is the main reason for miraculous performance as compared to other commercial nano ultra lube

The whole point of testing is to test extreme conditions inside the engine.
These types of conditions only happen during loss of oil pressure, racing conditions, oil scarcity, sudden throttle blip under load etc…
Regarding selection of bearing race, it is metallurgically atleast 10 times more harder than the ball being tested and yes it is still made of bearing steel and perfectly simulate, aluminium piston vs steel, softer ring vs steel, actual bearings inside engine, crank journal bearings etc…
If you pay extra attention to detail, conditions for the test were kept exactly the same so that it would bring up lubricant’s quality.
The whole point of testing with the same rough bearing race is to simulate what engine oil does to a new engine whose bore has scratches from honing marks either from factory or from lathe.
The tests done were carefully engineered tests keeping in mind about various aspects of lubrication like hydrodynamic, boundary, mixed, severe boundary and extreme pressure lubrication scenarios. Although these aspects were not talked about in detail in video, target audiences are common people.

Higher viscosity demands more anti wear additives in short just because higher viscosity oil molecules are larger than nanoparticles
Very simple

Application of lubricant on both surfaces is not mandatory however it was done to convince viewers however it was missed by mistake in case of mobil 1, however in the video of “truth about engine oil” where mobil 1 was applied on both sides and results were still much worse

This is a purposefully designed test to show superiority of shell over mobil 1. If the tests were inverted the result would indicate how much worse mobil 1 would really be which is not our intention. Also it proves a point that if Nano lube was applied once in any engine and if the shell is continued without Nano lube by any chance it would still be safer for a while because Nanoparticles would still protect the engine from wear. However the other anti friction and heat reduction qualities of Nano lube would be lost.
