I'm not sure this is a great example, In a lot of cases the medicines that have been around longer have proven their safety and effectiveness.
Do I Need API SP?

There’s an old HIV drug that’s safe and effective, but you have to take like 3 pills 3 times a day. There’s newer drugs where you take 1 pill instead and that keeps the virus disabled. I can come up with many more examples, like elevated eyeball pressure drops or specific female anti-cancer vaccines, all of them will be better than anything that existed before.
If it wasn't better than the current standerds and didn't pass approvals it would not be in the market.
Exact same thing with SP oils.
Lol, so this conversation got seriously side-tracked by that comment.
There's no doubt that advancements in medicine exist.

Suffice to say motor oil should not be compared to medicine.
And I would do a lot more research before I put something into my body versus putting SP oil into my vehicle.

Here is one reference to the contrary:

You can run SP oil for next 150yrs and during that time period ICE vehicles will be thing of the past. They are on start of their demise now, etc.
But that wasn't really my point. All that time/effort/$$ for these new oils that save just a bit on carbon footprint, outdone by adding more ICE vehicles to the roads, should be using all that time/effort/$$ on EV and H technologies.

You research all the foods you eat
Foods in general are horrible. Finding good 100% organics is hard to find.
You open that article and it literally starts with
Cancer drugs that speed onto the market based on encouraging preliminary studies
We are not talking about that aspect really
Boeing MAX that was rushed thru the approvals isn't a great example either. My point was about something else
Hi
Is the SP wear test result improvement shown in wear chart in post 11 of this thread also for the 40 weight oils and higher.

I don't think so, pretty sure only OW-20, 5W-20, 5W-30, and 10W-30l fall under GF-6. Lower viscosity levels like OW-16 fall in there somewhere.
I had that backwards, the GF-6 is for fuel efficient viscosity grades, API does cover the heavier viscosities.

For the timing chains, it has to do with the high levels of soot that a direct injection engine creates that gets into the chains. Direct injection engines have just as much if not more soot than a diesel.
I very much doubt that

Just do you a simple search of soot in TGDI and timing chain wear.
"Do me a simple search," huh?

API SP brings other improvements besides LSPI, like better timing chain wear protection.

Do you a simple search meaning, search the Internet. It’s a New Orleans thing sorry.
You're the one that made the unsubstantiated claim of "Direct injection engines have just as much if not more soot than a diesel." The burden of proof for that, my friend, is on you.
I think @930.engineering is curious too.

I seriously don't understand why anyone here would ever argue about motor oil.
