5w30 in a car spec for 0w16

[Zaedock]

Obviously you didn’t listen to what he said. In the end he said they see damage from using anything other than 0w16.

I suppose Toyota dealers in Northern climates have a lot of work in the middle of winter, because these engines are pumping maple syrup.

So why does Toyota RECOMMEND 0w-16 for 4 cylinders, but 0w-20 for V6?

Was going to post something similar. It seems a lot of people still don't understand that the biggest contributor to viscosity is temperature. If engines were truly as sensitive as some believe, when winter hits, they'd all blow up.

This is so true. Whenever I see the goofy "it gets damaged by anything other than..." I think of this.

So much nonsense here in this thread and just in general with regards to oil grades and "engine damage".

 

[kschachn]

Obviously you didn’t listen to what he said. In the end he said they see damage from using anything other than 0w16. In the manuals it says if 0w16 is. It available, 0w20 can be used to top off but needs to be changed with 0w16. Also this 0w16 is nothing new. Japan has been using it a long time and actually they have 0w8 in their new Toyota’s. I also want to add bc I see your avatar is a BMW emblem. What do you think happens if you don’t use an oil with the LL01 or LL04 certification long term??

No engine, ever has been damaged by using an oil with a higher grade than what is recommended. You know why they word it that way in the manual, right? It's not for a mechanical reason.

Plus comparing an approval with all the manifold requirements for things other than viscosity is not meaningful. If you use an oil without the proper BMW approval but with the required minimum HT/HS then the grade isn't going to be what causes a problem.

This whole thread has been an absolute train wreck of misinformation.

What do you say to my face,
with my 400,000 miles of appropriate usage of 0W16 ?

If you can explain how that relates to what I said perhaps I can.

Am I providing some of the content which constitutes part of "this whole thread...[of] an absolute train wreck of misinformation ? "

Some of us are interested in having a discussion about the current state of modern motor oils, rather than standing up for the honor of thick motor oil.

Good grief. OP drives a Prius Prime spec'd for 0W16.

 

[kschachn]

Good grief indeed.

As a fellow traveler that has one vehicle at nearly 450,000 miles and two at 300,000 such a feat is not without effort. But when I used to go to California quite often for business I saw many vehicles at those miles, it's amazing what a long commute can result in terms of miles.

 

[DirectRejection]

I certainly would not use 0W16 in a Toyota Echo with your acrued miles !

I would use HPL HDMO 10W20, naturally.

The manual words are not that explicit and says nothing about "topping off". The way it's written, if someone changed their oil and couldn't find 0W-16 then they could use 0W-20, but change it back to 0W-16 at the next oil change ... which could be 10,000 miles later.

So if 0W-20 is going to "damage" the engine it would certainly do in within 10,000 miles of use. If that was the case, Toyota wouldn't have that statement in the owner's manual. Plus, there is not one word or big WARNING box in the owner's manual saying that using anything but 0W-16 is going to damage the engine. If that was the case, Toyota would have it all over the owner's manual.

Well i'll burn through the 6 jugs of 0/16 I bought and decide from there. I'm more confused than ever after reading these 13 pages

i made a post about the 2021 yaris hybrid inline 3 stating everything from 0w-8 to 5w-30 in the owners manual and a 0w-16 using 2020 prius or camry using the exact same engines as here in the US can use up 0w-16 to 15w-40 in the owners manual. More film thickness is proven to give more protection. Thats why ford bumped up to a 5w-30 in some of the new vehicles and issues tsb's for old ones to make the switch.

Maybe, maybe not. 10,000 miles is not that long for some. If I had to throw a dart here my guess is that any detrimental effects would happen further down the road. 0w20 might not have any negative effects on the engine but something like a 40 grade could down the line, perhaps 30k or so? It is a unknown factor.

On the other hand, the vast majority of these new engines are running on 0w16 just fine. I don’t see the need to run higher grades over what Toyota is stating in the manual.

So nobody, including the Toyota Tech in the posted videos, have said what kind of "damage" will occur if nothing but 0W-16 is used in this engine, even though the OM says you can use 0W-20. And the owner's manual in other countries say you can run even thicker than 0W-20. If running anything more than 0W-16 was really going to damage the engine, the OM would have a big warning saying so - that's something Toyota or any other car manufacturer would not ignore if that danger really existed.

On the other hand, the vast majority of these new engines are running on 0w16 just fine. I don’t see the need to run higher grades over what Toyota is stating in the manual.

Yeah, I sure it would too but some people like a bit more viscosity (MOFT/HTHS) headroom.

It does say that in owners manual. I have a 2020 Toyota Camry and a 2018 Honda Accord.

And how is it maple syrup? It’s super thin

V6 is totally different engine. Don’t share same technology.

I

BMW recommends ll-01 fe (0w-30) for my X3. But instead I use Castrol or Valvoline 5w-40 (LL-01). I really don’t care that BMW says to use ll-01 fe in ll-01 applications. Some of the newer BMWs say to use the 0w-20 whatever approval oil but the manual also says one can use ll-01 fe or ll-01.

No dude, LL-01 or LL-04 is not recommended, it is required. I have worked at BMW. You can use whatever brand you want as long as it meets the the spec. I have seen long term damage from not using that spec oil and people trying to extend the drains. It’s stamped all under the hood. Pennzoil is the lubricants supplier for BMW as well.

Obviously you had a hard time reading what I wrote. BMW says to use ll-01 FE. I use ll-01 instead.

Oil is thinner when it’s cold?
