Nanoparticles in oil is the next thing

When the content of the modified copper nanoparticles in the said engine oil was 0.05%, they had the best tribological properties, which improved the antiwear and friction-reducing properties of the said engine oil by 1.57 times and 27.6% respectively. This was attributed to the forming of boundary lubricating film by the copper nanoparticles deposited on the worn surface.

Maybe Slick 50 was not so bad an idea?

I used to use this 20+ years ago, based on extensive watching of 1 armed bandits at fairs.

Given that copper is a catalyst for the oxidation of petroleum products, I won't be adding any to my oil.

RLI uses lots of Cu in some of their additive packages and formulas. You might take a look at them if you're interested.

Patents from 1965 to 1975 had a lot of copper additives.

Guess the Asian groups are cashing in on expired patents.

Slick 50 was not a good representation of what can be done with this family of additives (in fact its poor).

Nanoparticles are making quite a buzz for the refrigeration lubricants. They are showing a lot of promise from the papers I've read. It's still too early to tell though.

Search BTOG for WS2, Tungsten Disulfide. The stuff is more lubricious than any other material. Higher temperature and pressure tolerance. Chemically inert as far as oil is concerned.

Any technology sufficiently advanced is indistinguishable from magic.

Don't worry, there will still be some on here who will state; "too expensive, not needed, impractical, too advanced, overkill" etc., etc. just like they do with advanced synthetic base stocks and other add packs.

This DESPITE this being a site which is supposed to be (or at least WAS at one time) one which was made to discuss oil/tribological tech.

That's why it's nice to have experts here to let us know some of the underlying reasons beneath these trends and "innovations." Thanks!

Wait, are you saying they dreamt of nonoparticles back in 60's?
