What Toyota model? I could give my Corolla vegetable oil and it'd last 400k miles if changed by the manual recommendation (mild sarcasm). I've run NAPA syn and Super Tech and TGMO. They all last for reasonably normal intervals and reasonably normal driving conditions. Don't sweat it. Buy a cheap one with the correct symbols and certifications and you'll be fine.

OK, so page 4 is the 4-ball wear test, which in no way is relevant to engine oils. There are two version of this test, one for greases, one for gear oils. It's a test for EP applications, a category which engines don't fall under.
Page 5 is TBN. This isn't relevant to oil performance in service, it's more germane to service life, so it will be higher, typically, for an extended drain oil.
Page 6 is CCS. All tested oils are within range with the heaviest oil (Redline) being the highest, that shouldn't be surprising.
Page 7 is Teost, All oils with the exception of the one that isn't API approved in the first place (Redline) passed.
Page 8 is Noack, all look pretty good except for Lucas. Redline, being the heaviest, also had the lowest Noack, no surprise there.
TGMO is made by ExxonMobil; so, Mobil 1 0W-20 EP would not only be a somewhat similar substitute but would give the benefits of extended drain (PAO base oil and more antioxidant).
TGMO 0W-20 used to have POE—not sure now. None of the listed oils have POE, but ILSAC Mobil 1 oils have AN, which is a less effective but alternative solvency and cleaning substitute.
Nice cut and paste there about the test being a "gold standard", along with an Amsoil advertisement stuck in for added benefit.
ASTM D4171 can be used as a screening test for lubricant qualification but it does not translate into ICE operation. As someone who actually did work in a research laboratory I can tell you that yes we did do certain screening tests that weren't representative of the final product properties. This is one of them.
You don't really know what you're talking about do you?

Any synthetic will be fine for that. I'm more worried about my CVT than engine oil.
Not to mention that 100°C is 212°F...
Which really paints the rest of his novel a certain shade of BS.
I thought TGMO 0W20 was the same a Mobil Super Syn 0W20.

From what I can find it's way different, TGMO has a ton of moly in it, like 600 or 700ppm.I thought TGMO 0W20 was the same a Mobil Super Syn 0W20.

You may be right. A quick Google FU says its Mobil Super Syn with a special add pack.
My 100k Tundra seems to enjoy Castrol the best. I might just grab some OEM and
give it a try. Lord knows we love moly.
Happy Tanksgiving (pun).

The reason the 4-ball test isn't included in any of the API or ACEA sequences is because it isn't relevant. Full stop. Marketing fluff, internet cut and pastes and all that nonsense cast aside, if you look up the testing protocols, they clearly state that these are EP tests, and EP conditions don't exist inside internal combustion engines, that's why these tools are used for gear oils and greases but the same manufacturers don't use them for engine oils. Why do you think AMSOIL is the only company that uses the results of this test for marketing engine oils?
The response to this question also applies to the 4-ball test, not just the one-armed bandit that the RP peddlers are famous for:

There are certain oils in the market today that use EP (extreme pressure) additives in their motor oil that are really designed for gear oils and not motor oils. Extreme pressure additives are typically not used in motor oils for a number of reasons, but the most important reason is that they...

I like AMSOIL, but a cut and paste of other material that has technical errors isn’t doing anyone any good.
If we’re talking about oil, and we’re technically correct, fine.
If we’re answering the OP question, also fine.
But specious posts that fail on both counts aren’t helping.

Oil switched out to Valvoline Extended Protection 0W-20 for about 17.50 with MIR after tax. She seems to like it just fine.
