Here is another video from Lake Speed Jr., the YouTube tribologist (certified lubrication expert), on what aftermarket oil additives actually do inside an engine (spoiler alert...it ain't good; some is pretty bad).

Off the shelf oil additives above are nothing like the essential additive packages the oil company chemists blend into clear base oil to produce a finished engine oil product...and hydraulic oil, gear oil, greases, and all other lubes, each different from other types. There are four big additive makers, Lubrizol, Afton Chemical, Chevron Oronite, and Infineum (ExxonMobil + Shell) who sell their additive packages to any oil maker. These essential additives include viscosity index improvers, anti wear agents, anti foamants, anti oxidants, corrosion inhibitors, extreme pressure agents, detergents, dispersants, friction modifiers, pour point depressants, dye, and others. Amsoil has a good run down of a typical add pack that they buy, but they don't tell who they buy it from. https://blog.amsoil.com/more-than-you-ever-wanted-to-know-about-motor-oil-additives/

Lubrizol, one of my high-school classmates worked and retired from this company as the head of China’s headquarter. Heard many stories about the oil and fuel additives many people don’t know. He once told me Costco uses their gasoline detergent pack as the Top-Tier gas. And I started to use Costco gas comfortably since then when I’m in California instead of Shell gas in Texas as the gas price in CA is too high with Shell. And Lubrizol once developed an ingredient for asphalt which can make the road surface lasts at least 3 times longer. But None of the States is willing to use it, not because the price as the price is low, but it could result in much less road maintenance projects which seems going on forever, and the State governments aren’t happy to see ⋯
