That SAE grade is not the same today.
0W-16 Strength & Durability

READ THE POST. I'm not going to type it twice.
A bitter pill for many to swallow.
But to keep it real I'd consider changing things around slightly to avoid further debate, maybe to this for the second sentence: "There are no other technically significant advantages, at this moment in time."
That remains one of the big selling points of low viscosity oils today. Easier cold weather starting. Nothing has changed in that regard, with the exception now they're pushing it all year long, in all climates because of CAFE.
Except for the little caveat in the owners manual that mentions, "A higher viscosity may be better suited, for severe conditions".
Again the SAE grade then is not the same as today. There was no HT/HS at the time but had there been the value for those oils would have been around 2.9 to 3.0, that is where the old Mobil 1 5W-20 fell (which was originally marketed as a replacement for 10W-40).
And there is this. So yeah, why not 0W-16? It's not going to matter either way.
"Why do cars in Japan have such low mileage?........... The Shaken Law Prompts People to Sell Early. You should know that used cars from Japan usually have low mileage because they are put out of service after only four or five years.
According to the Fédération Internationale de l'Automobile, a car in Japan travels a yearly average of over only 9,300 kilometers (5,800 miles), less than half the U.S. average of 19,200 kilometers (12,000 miles).
How long do Japanese people keep their cars?............ As a result, most car owners in Japan write off their cars after 10 years and buy new ones. Hundreds of thousands of perfectly fine automobiles are demolished every year.

Are SAE grade given to US motor oils the same as those used in other countries (Japan keeps coming up here)?
If a foreign manufacturer wishes to certify the oils against the SAE then it is. There is only one SAE.
Thanks!
With the amount of Prii and Camrys serving as Ubers and cabs, there should be data about how well 0W-16 holds up on those. Or how many of them end up at the Copart auctions with blown engines.
Japan has a CAFE type of orginization/department that puts fuel economy requirements on vehicles, and it's as stringent as CAFE or even more so. We all know that one way to achieve better fuel economy is to use smaller engines and thinner oil ... 1+1=2.

I’m still waiting for the disadvantages. We are not seeing engine failures due to lubrication on these oils. There might be slight benefits in decreasing wear using a higher grade of oil but again we don’t have evidence of that either.
Wear is not decreased by a lower MOFT. Physics matters.
One huge disadvantage is the large cost in engineering for both engine designers and oil formulators. All this development hasn’t come for free.
And thanks but no thanks for the trade-off between film thickness and fuel economy. As the automakers have stated, the current oils provide adequate film thickness under most driving conditions. I guess I’m just not into adequate.

I understand that. What I have not seen are any scientific studies that show wear rates between different oils.
We certainly have. Data has been posted here multiple times showing the relationship between wear and HT/HS. Wear increases below an HT/HS of approximately 2.6.
Unless your one and only goal is to increase fuel economy then I’ve never understood the reasoning behind championing for the lower viscosity oils. If increasing a CAFE is all one cares about then fine. But is that all?
Of course you won't see massive evidence of "blown-up" engines on vehicles used normally on the streets. Give me a car to run flat out all day on a track with 16 or 20 and you might see an engine failure depending on how they designed the engine oiling and cooling system.
The average Joe driving around isn't going to be able to detect any added wear, but many engine studies/tests have shown that thinner oil can cause added wear compared to thicker oil.
HTHS viscosity and MOFT headroom matters ...
