How about posting up the pages where it specifically says you can only "top-off" with 0W-20 and the engine will become damagrd if anything but 0W-16 is used.
5w30 in a car spec for 0w16

Here's the full OM. Can anyone find any statement where it specifically says you can only "top-off" with 0W-16 and that using anything but 0W-16 will "damage" the engine?

Yep, that last highlighted statement wouldn't be in the manual if anything thicker than 0W-16 caused any kind of engine damage. Toyota isn't that stupid.

^^^ I'm asking for the "damage" statement.
Yep, what's highlighted is a statement that basically says thicker oil is better than thin when the engine is sressed more - no surprise there. Totota wouldn't have that statement in the OM if anything above 0W-16 caused any kind of engine damage.

I’m going to end with this bc Im actually a technician that works in the field, have friends that work in field as well as technicians. I have worked for several makes import and domestic. This right here is why manufacturers won’t just warranty anything now. Warranty now wants everything documented and investigated to see if it is operator error or an actual manufacturer issue. Honda, Toyota and Nissan use to be so simple if there was a problem, if the trans had an issue, put a new one, if the engine had an issue replace it. Now manufacturers are looking for every way possible to not have to pay on their dime, making a technician investigate and get down to the source of problem. The domestics are the worst. Just put what the **** manual calls for on every lubricant. We just can’t understand how people pay this kind of money for vehicle and want to either go cheap on lubricants or want to neglect what the oil cap or owners manual says. Especially on the Euro cars everything is tamped under the hood with warnings.

The manual allows for a thicker oil. We are following what the manual allows.

Allow me to amend what i wrote on one of the previous pages in this thread.
OP, Go with the 0W-16 and if using 0W-20, only do so in between oci of 0W-16 as stated in the manual. Will a 5W-30 work? I don't know, i didn't develop this engine. My opinion is that 5W-30 will work just fine. This and $.50 will get you a cup of coffee at the dealership waiting room. If something goes wrong with your car where the oil receipts are requested and they deny you warranty work because "you used the wrong oil", nobody here is going to contribute to your legal fees.
Yes, they will have to prove the oil caused the issue, but In the meantime, you will have to hire lawyers and deal with the anxiety of the entire ordeal. This is a HIGHLY unlikely scenario but it's one that is completely wiped away by using the recommended oil.

There isn't one. Search the OM PDF for the term "engine damage". Nothing what so ever related to oil viscosity can be found.
The way the OM is written, if someone used something that was SP rated and thicker than 0W-16, Toyota would have no leg to stand on. If Toyota or any other manufacturer doesn't want to allow anything besides a specific viscosity (or range of viscosity), then they need to explicitly call that out in the OM, especially if anything outside that is going to cause any kind of engine damage and void the warranty, with a big warning statement. Really not hard to write the words.

Just so you know extended warranty and manufacturer warranty does have us sample oil and send off to lab. Actually just did one today bc the engine has a failure with 83,000 miles. Extended warranty came in and watched the tech put the sample in bottle and label it. Like I said I work in the field and they are looking to see if the correct oil, etc was used before they pay for an engine job.

When I get to the car I will show the manual. My wife drives Camry
Idiots?
Here's the 2020 Camry OM. Has the same words that a thicker oil can be used for more stressed engine use. And again, no words related to engine damage will occur if xW-20 is not used. Search the PDF for the words "engine damage".

Yeah people who think they know better than the team that designed, and tested the engine and components.
You mean the same engineers that flowed the spec info into the manuals, that say thicker oil is better for engine protection when the engine is used for high RPM/speed and towing.
