I've always found this discussion odd because on my Honda I switched it to 0w-xx from 5w-xx oils AFTER it had went 200k miles. And it has been running on 0W-20 for the past 30k miles and I plan on running it well into the 300k.
10w30 was definitely the move

Refer to OP's testament.
You know that the "W" stands for Winter, not "Weight" right? This is simply a classification of an oil to pass CCS and MRV at very low temperatures, it is not a viscosity.

Based on his posts in this thread I don't think he knows anything about what he said.

Going to do a UOA at the end of this OCI and see what it says.
Just thought I'd share!
Have you checked your valve clearance adjustment?

No, your vehicle will not explode if you use 0w- or 5w-.
With that said, optimal longevity is NOT why CAFE mandated viscosities are here.
10w-30 is indeed STOUT.

So Mobil 1 or Castrol 0W-40 is not STOUT?

Last I checked, 0w-40 wasn't a CAFE viscosity. The Winter rating doesn't make or break CAFE, it's designed to make an oil as universal as possible so that it is appropriate regardless of whether you are in Dallas or Anchorage.

Off subject. No one said that, and those oils were not part of the discussion. They are not CAFE oils.

Not off subject at all considering the point of your statement was directed at the winter rating of the oil, not the operating viscosity.
How about a 0W-30 then such as Castrol EDGE 0W-30? Is that not STOUT?

The subject was understood (by almost everyone) to be CAFE oils.
I will not participate in your "straw man" debate.

Yes, you can call it that and "bow out" of the discussion but it gets to your misunderstanding of what a winter rating means. That was my initial point.
CAFE actually drives the operating temperature viscosity much more than the winter rating. This is illustrated by the designations such as 0W-16 and 0W-8, no new winter ratings have been made. The winter rating in CAFE-speak is a minor component of the process.

Over the decades, modifying these ingredients has yielded greater fuel economy. The preferred strategy for formulators and additive makers is reducing the viscosity of the engine oils.
"Viscosity is really drag," says Mark Sztenderowicz, global manager of product development for automotive engine oils at Chevron Oronite, the lubricant additive arm of the big oil company. "Moving a thicker fluid takes more energy. If you reduce viscosity, less energy is consumed in the moving parts and in pumping the fluid around the engine."
This strategy can be seen in the evolution of SAE International grades of oil, such as 5W-20. The lower the code numbers, the lower the viscosity. The number before the W—which stands for "winter"—signifies the cold viscosity performance; the one after it designates the viscosity of the oil after the engine has warmed up.
In the early 1990s, 20W-50, 10W-30, and 10W-40 were the most popular grades, Henderson says. Now the most common ones are 5W-20 and 5W-30.
Newer engines use 0W-20, 0W-16, and even 0W-8. How much fuel efficiency benefit comes with lower viscosity varies from engine to engine, Sztenderowicz says. But, for example, a change from a 10W-40 to a 0W-20 oil, assuming identical engines, could bring up to a 3% improvement, he estimates.
Rolling out such lower-viscosity products poses challenges, Sztenderowicz says. At lower viscosity, base oils are more volatile and likely to evaporate. Solving this problem necessitates higher-quality, and often more expensive, base stocks.
And the changes stretch beyond base stocks. "As you go to the thinner oils, you need the additives to work a little harder," says Cyril Migdal, head of global application technology for lubricant additives at the chemical maker Lanxess. "When there is less film thickness, there is a higher probability that engine parts can come into contact with each other. If they come into contact, you will have wear."
More and better additives—antiwear additives, for example—might be needed to protect the metal surfaces, Migdal says. And because thinner oils are more susceptible to oxidation, they require stronger antioxidants.

I am not "bowing out" of anything. I know perfectly what a "winter rating" is. (35 years of petrochemical technical experience). Just because you were incapable of following the simple subject matter at hand (CAFE oils), does not mean I have to participate in an off subject side argument you are trying desperately to use. Again, everyone but you understood the subject of discussion.
Class over. You are dismissed.

Okay good, it just didn't seem like it by your comments. You would agree that CAFE isn't about the winter rating anywhere near as much as it is about operating viscosity, correct?
Also in regards to OVERKILL's comment,
