0W-16 Strength & Durability

Like I said, I am only the messenger. Source is a toyota tech who has seen problems on hybrids from owners who did stick to 0w16.
Think people have posted snip-its of the Toyota OM that has the "use thicker oil under extreme conditions" type of statement. So that kind of blows that Tech's statements out of the water.
 
Yes ... but look at the history since the first J300 was published. Interesting changes along the way.
But nothing relevant to my statements....

J300 revised in 1999 and again most recently in 2015, that doesn't mean 5w30 was spec'd completely different to the 2015 version...

Besides, don't many of the studies you guys always reference use the older generations of J300 oils?

Like I said, the viscosity "grade" definitions have changed in J300 over the years. It was somewhat relevant to your question in post #184.
 
For me the proof is in the pudding as they say. Lab results can be interesting but in the end I care about my effect as a consumer. So lets say I go out and but a 2022 Camry. I drive it for 15 years and put on 200k miles using a 0w16 oil approved by Toyota and respect the OLM. Please list me my disadvantages.
There is no OLM on it
 
we'll see soon if the current generation of Prii (0w-16) are as bulletproof when they get over 100k miles as the prior gen. of Prii.
I still see quite a few as Ubers, Lyfts and Doordashes. Despite the fact the average Uber driver has shot/no credit and has to rely on subprime lending or a leasing program, the Prius(and the RAV4 Hybrid) is still the aspirational rideshare car. As a matter of fact, I saw a brand new Camry Hybrid with CA dealer temp plates and a Uber decal/SFO airport permit on it. That calls for 0W-16.

I’d be more worried about head gaskets, if the 2010-2015 Gen 3 model is any indication.
 
One thing you might want to consider is what oil the manufacturer calls for in other markets that do not have CAFE requirements. Most automakers sell the same or similar vehicles with the same engine worldwide. It isn't uncommon to see them spec a 0w-20 oil in North America while spec'ing a somewhat heavier oil (0w-30 or 5w30) in much of the rest of the world.

I think it is worth noting what oil these automakers think are best suited for their engines where CAFE standards are not a consideration, taking into account what the climates are in those various areas of course.
My 2019 Miata calls for 0w-20 in North America and gives a choice of 0w-20 or 5w30 Mazda oil in Europe. That seemed odd but the Europe oil is a different blend, low SAPS. Also the extended oil service times are regulated in Europe compared to North America. Still the Miata ships with 0w-20 to Europe. Could the long oil service be a factor, or driving on autobahn?

Logistics. When Honda called for 0W-20 in the Insight in the 2000s, all their Japanese plants and eventually their US/Thai plants filled with that. It makes no sense to separate oil fill on the assembly line based on country.
 
FFS, no dog in fight in 0W-16.

Researched 0W-16 as I am in the market for a Venza/Toyota Hybrid generation whatever number it is now.

So the manual blows you out of the water

You think Toyota would put the statement in the red box in the OM if they thought it would really harm the engine? Someone could be running 0W-20 for a full OCI ... oh the horror !!! Still blows the so called "Toyota Tech" and your research skill out of the water. 😂 ;)

Toyota puts that "gotta change back to 0W-16" at the next oil change to appease their CAFE ruler.

This is out of the 2022 Toyota Tacoma OM. Same statement that is in most Toyota OMs for many years ... it's been discussed many times. Pretty much says you can use any oil thicker than the "recommended" viscosity if you want to based on the conditions stated.

Note that the same statement underlined below is also in the OM snapshot you posted above.

But the 0w20 for North America you can get here and is made by Idemitsu, the Europe Mazda blend sold at dealer is made by Total, two different blends for Mazda oil.

I’m talking about the manufacturing process - it’s easier to “localize” a car with that country/region’s specifics(drive side, lighting, restraints and even HMI/UI elements) but engine oil is filled at either the engine plant or at the end of the line with the rest of the car’s fluid charges just before QC and transit. The Japanese pride themselves on efficiency - they aren’t going to keep multiple grades of oil on the assembly depending if the car is shipped to the Americas/EMEA/APAC.
 
........... Which owner's manual says that? Mine doesn't.......

It say's it right in the manual for my 2018 Toyota Camry. (2.5L 4-cylinder). The "recommended" oil is 0W-16. It also say's if 0W-16 is not available you can use 0W-20.

Then has some nonsense that if you do, you have to change back to 0W-16 at the next oil change. As if your car is going to know. The manual is full of this kind of tricky worded nonsense due to CAFE.

The owners manual for the exact same car, with the exact same engine that is sold in Australia, shows oil viscosity up to and including 15w40 can be used.

2018 Toyota Camry Hybrid manual from Australia: 0W16, 0W20, 5W20, 5W30, 10W30 and 15W40 are all approved by the factory.

Well you can use a 0W-16 that is nearly all PAO balanced out with GTL and AN, or older oils likely to have Group II-III...
 
I have put soon 600K on my last three Ford Duratech 4 cyl engines including my two Fusions with trouble miles with the engine. To date no oil consumption in my normal 10K OCI with M1 20 wt. oils.
You run quality oil and the operation of your vehicles is conducive to long engine life. Tig you are doing every thing correctly !
