Depends on who makes the oil. From what I've found amsoil makes one of the best 0W30 oils out there where as the Mobil 1 0w30 performed worse on film strength tests than the 5W30 equivalent.

As for the supposed tests where Mobil 1 falls down; don't believe everything you read; Amsoil is notorious for rigging irrelevant tests which favor their oils. Go over to BobIsTheOilGuy.com and look at the UOA database; Mobil 1, Castrol Edge, Amsoil (often called Scamzoil), it makes no matter, they are all excellent oils.

I think I might just try some 0W30 out when my next change interval presents itself.

Not sure what you're trying, but I believe we're both on the same page. I'll quote again what you said, "The fact is, a 0W-30 trumps all other xW-30 oils regardless of climate." You reiterated that this statement is fact. I simply claimed that it's a generalized statement and is NOT a fact. I provided an example with motorcycles that proved how your statement is false.
About motorcycles, I also said "I'm sure you didn't mean to include those in your absurdly generalized statement, but that's the reason you shouldn't state such huge claims as fact." You are the one who made a huge generalization and claimed it as fact. You even said "Sorry, it is very definitely a fact." when I simply stated that it wasn't. Your statement as it was written was not a fact, and I believe you agree with this.
Why assume? I specifically stated I was considering a fully synthetic 15W-30 for high performance use on the street. Obviously Synthetic > Conventional.
There's also been some argument between you and Darksyne. At least from what I read, I think that you're both saying the same thing. Obviously oil viscosity increases as it warms. As I understand it, 0W-30 is basically a 0 weight oil that thickens as it warms, because of the viscosity improvers. Same with the other oils. The base stock is the 0W or 5W part, and the viscosity improvers thicken the oil to the operating temperature. Either way, I've learned a lot about oil from arguing on this thread!

Okay, one final comment; another assumption is being made in that all oils require viscosity improvers (VIIs) to meet multigrade specifications; the beauty of many of the higher grade synthetic oils is their base oil is so pure they require few if any VIIs to achieve a multigrade qualification.
I guess this is the only part I don't understand. Can you explain this a little more clearly for me? I understand and agree that oil inherently gets thinner as it gets warm. But shouldn't 0W-30 have more viscosity at operating temperature compared to 0W-30 at room temp?

No, at operating temperature, 0W-30 and 10W-30 should have the very same (or similar) low viscosity; at room temperature all oils, regardless of whether they are 0W, 5W, 10W..., will have a higher viscosity (the higher the first number the higher the cold viscosity).

This is what I was wondering. It makes sense that any hot oil would be thinner than the same one cold. I guess I misunderstand the oil weight as viscosity then. For 5W-30, the 5W is not a viscosity of 5 at ambient temp, and the 30 is not a viscosity of 30 at operating temp. The 5W has more viscosity than the 30. This makes sense, but is just weird. Almost seems like the numbers should be reversed, as the oil loses viscosity as it warms.

Oh come on guys, I put 0W-16 in my TL for my trip back to Michigan and got 47 mpg at a fairly consistent 100 mph.

Well I just got a wicked Black Friday deal on some Redline 5W30 oil which I'll be using next summer 😁 One of the few group 5 oils commercially available since it actually advertises being an Ester based synthetic.
Ill do a UOA on the redline in the summer and some 0W30 Mobil 1 next winter and compare them to see if 0W30 is worth the hype :p

I have two 2 Gen TL-Ss and I have used 10w30 in them for years and never had a problem. I live in Florida. You won't see any difference between 5w30 and 10w30 at temperature. I only went with 10w for the extra viscosity at start up.

Keep in mind you cannot prove a positive with a negative; said another way, a lack of issues (so far at least) isn't proof you've been using the best oil for your engine.
