2025 Toyota 2.5L Engine Oil Viscosity Update.

I have no idea what I am doing on here. It must have posted this page from Toyota's Warranty information pages a dozen times. Sorry for that. Anyhow, where it says engine oil selection, it says refer to your Owners Manual for the specific engine oil recommended. The key here is the word recommended, they probably should have used the word "required" there. That would remove the confusion.
They can't require it.
 
guess what, if warranty department rules that engine problem was caused by engine oil, they will not care if you have receipt or not. Forget about viscosity. They will say that something is wrong with the oil and that you should contact oil manufacturer for any reimbursement. Sure, you can hire a lawyer and pound the sand

Bottom line, if you really paranoid you have to forget about DIY and only go to dealer for everything.
Or just stop worrying about this, and be more adventurous .
 
Does stipulate mean require for warranty coverage?
There is strong language here from MB, stating to "only" use certain viscosity grades and viscosity restrictions within a specification must be observed.

It's the same at our local toyota dealer, vehicles that call for 0w16 get bulk 0w20. I believe vehicles that call for 0w8 get 0w16, last time I was there out of curiosity I asked the price for 0w8 and they didn't have any. Kind of interesting how dealers use whatever they want yet people are scared to use different viscosties.
My parents have a 2025 Camry that calls for 0W-8 “officially”. The local dealer used TGMO 0W-8 for both of the ToyotaCare services. The printed weights are for the US/Canada but thicker oil is, of course OK in the rest of the world.

Now that this car no longer sees gig work, I’m OK with the 0W-8 in it.
 
So, Critic, I guess you are showing this Mercedes language for comparison. The Mercedes says you MUST use certain oils where Toyota has no such language when it comes to engine oils. Thanks
Yes because an oil of a lower HT/HS can possibly damage the engine. And damage may not be covered by warranty.

Same applies to Toyota regardless of the wording.
 
While I do agree, the manual states that we can use a higher viscosity oil if we see higher speeds etc. but never states what viscosity.

That’s what’s odd to me honestly
It doesn’t matter, you can use any higher viscosity. Film thickness protects, and although the degree of protection is less at higher HT/HS it only really negatively impacts fuel consumption.

It really does show that the problem comes in with insufficient film thickness and not the other way around.

So how come 0w16 hasn't damaged my engine yet? Should I worry? 202,000 miles so far
