Very helpful to the uneducated but interested layman. Many thanks. I too wonder about the surface manufacture/prep as an aid to this increasingly lightweight world.
MoDTC and the others don't last beyond 2000 miles in a typical motor oil? that spiked my interest, and possibly explains why Redline and some Japanese spec oils use a lot of moly - to extend the useful life.

Not one single test can determine the lubricant’s ability to function in real applications and many tests are done for specification and/or marketing purposes only.
If lubrication engineers and mechanical engineers were better educated in tribology and tribologists were better educated in lubrication engineering, many open technical problems of today related to friction and wear could have been solved a long time ago.

Here is one that the racing community has been using for years. That well known non-chemist Mike Kojima introduced this to SR20 users in the late 90's.
Many, not me, used them then and continue to do so. They have some readable documentation that looks worthwhile. I don't know how scalable their process is but would hope that the ~$50/piston cost could be reduced. Good quality stuff.

No, they have many common fields of study.
What he is saying is that each area of study needs to broaden their areas of study for more overlap, and communicate better across those areas of study.
