We finally got some... 0W-8.

We at the Advance Auto finally got our hands on some 0w-8 oil. We don't stock this stuff, and most stores won't. We special ordered it for one of our commercial accounts. In fact, we still don't have any 0W-16 out on the shelves yet.

Anyway I noticed no API certification on it. It does say Made in the USA on the bottle though. Looks to a Mobil bottle?

Yup, Mobil …
 
Looks like they hope to transition to calling it JASO GLV-1 so people don't just get "whatever's close" with the traditional blank-w-blank viscosity description.

Not having an API license listed isn’t really important for manufacturer branded oils. Same for some branded oils for European approvals.
 
If Toyota's bottled oil is beefed-up like it's factory oil that gets added supplements for break-in, then I'd change my oil buying habits and begin shopping at Toyota dealership parts counters.

That goes for a handful of competition oils too. But from what I've read here by members, factory oils are built different - more stout than the dealership's official default oil, which generally always bears the vehicle manufacturer name.
 
I know it has been discussed before and I know the thicker=better train of thought is outdated, but at some point viscosity for the sake of fuel economy has to be compromising wear. I'm not an expert by any stretch of the imagination but common sense would dictate this has to be the case. Maybe in most driving situations it would be fine, but what about high load, high temp conditions?

For my '23 Toyota VENZA, I've been getting FRAM 0W16(with a filter) at my local AAP in 1 qt. only(no 5 qt jug) right on the shelves.
Also my local AAP stocks Mobil1 0W16 as well and is available in 1qt. bottle or 5qt. jug
No 0W8 of any brand yet.
Not that I can use it anyway!

Interesting! Our store doesn't stock any 0w16 yet. Admittedly we are a smaller, more commercial-based store and inventory varies a lot from store to store.

It’s not outdated. The physics of film thickness and wear are not violated. But there have been changes to engine design and oil formulations that can give “acceptable” wear with low viscosity oils.

The only real downside to a higher grade is a small increase in fuel consumption. Oil passages aren’t too small for higher grade oils, VVT systems won’t implode, engines don’t warm up faster, and engines don’t have electric oil pumps that controlled by the ECM, will shear off the pump drive gear. All those are Internet-amplified fallacies that along with others are common misconceptions about how oil works in the engine.

That last paragraph is a lot of wide sweeping OPINIONS that many here need to see PROOF of.

⬆️This is spot on

The urban legends run deep on the inter webs.

On my vehicles over the decades, I have found if I stray too far to the "thick side" oftentimes the engine doesn't respond properly or to the original intent - as it had run when factory new.

I am reminded of this very fact as I recently had to do this with our Ford 2.0L when I installed Mobil 1 5W30. I ended up draining a bit and substituting in its place I chose a companion in Mobil 1 0W16. All to save the newish sump rather that start over.

The opposite can also be true, as the 0w20 508 00 VW 1.4L required some help but toward the more viscous direction.

Have not seen shearing of oil pump shafts (lol) but I have noted weeping filter gaskets - along with the aforementioned performance issues.

I (referencing MOTUL) have come to call this viscosity tailoring. An adjustment sometimes required for optimum performance and response when the engine is at operating temperature. Just as off the shelf trousers are not a one size fits all product, So can be that container of motor oil.

This may all seem odd or unnecessary, but I am at certain time or circumstance compelled to act. - Arco
