I could swear we were pushing 1,000.
OW-16 vs 0W-20 viscosity specs - does it really matter.
- Thread starter SC Maintenance
- Start date
Good point. I was looking at the 2023 Prius and it takes 0W-16 as well. I just like to use what the factory suggests and in the OP's case I believe the 0W-20 would be just fine. I would use the 0W-16 if it were my car however Toyota's are built well and will most likely last for many, many years and miles no matter if it's a 0W-20 or a 0W-16.
I seriously doubt that Toyota puts "Crap" quality oil in their vehicles as the op stated.
What?! Reads like insanity on the face of it. But I need to know your concern. Is it operational in nature or just an "imagined" low quality - and therefor inadequate - dealer service ?
What Toyota is this? Camry or a Prius Hybrid or ?
Are you experiencing excessive engine noise when warm?
Other than hearing excessive engine racket - forget the spec sheet and KV100. You really wouldn't know the in situ HTHS.
On any passenger car engine run the thinnest oil that does not promote rod or chain noises at elevated rpm transition.
From my past new engine experience, large 4 cyl tend to require an increased HTHS in the sump for adequate operation.

Toyota dealer is very different than Toyota. Still your probably right that you can't even buy any crap oil anymore.

I am experiencing no issues or concerns that would point to any immediate doom. It was more an "academic" question than anything.
The application is a 2.5l dynamic force engine in a 2019 Rav4 - ICE model - not hybrid. Its at about 30K miles at this point.
Thick vs. thin along with the old “disparage dealers” content.
Then why say it was? Just to post crap?

Maybe not crap, especially compared to oils of a decade or so back, but certainly lower quality oil compared to M1, Pennzoil, Valvoline, etc. Just because an oil "meets the spec" doesn't mean that it's a quality product. The API spec can be met by some pretty mediocre oils.

Since its apparent on this forum you don't like me - why respond to my posts - just to post crap?
Crap is a relative comparison. This entire website is about comparing different brands and weights of oils I guess by your measure the entire site is "crap".
Whats interesting in my mind is that 0w-16 KV100 overlaps 0w-20 KV100 - and that doesn't happen in the API specs at weight higher - so there is obviosly other parameters to discuss. If you prefer not to discuss them, why participate?
Since you don't care for debate on thick vs thin - why even open the thread - the title is pretty clear on what its about?

No, that's not how that oil pump works. It's not a computer fan.
I dumped mine and went to 0W-30 and never looked back. I first tried 0W-20 at 400 miles, and the engine ran quieter when idling at operating temperature. I then went to 0W-30 after that, and it ran much quieter. And I dump the filter every oil change. I'll save $5 somewhere else.
I've never had the vehicle back to the dealer since I bought it.

Some educational content:
As I stated up above, it used to be 5W20 VS 5W30. Now we have evolved to 0W16 VS 0W20. Let the "thick vs thin" debates begin!
They are good motors. A lot of Mazda input went into them. Nobody should worry about running the oil that Toyota recommends.

You must have meant devolved.
I think now it's thin vs. thinner.
These threads are always so much fun, especially when HTHS, additive packages, formulation, etc., are almost never discussed.
As @OVERKILL likes to say: Engines can't be that sensitive to viscosity. And they are not.
No doubt about it. When I upgrade the oil, like I did in the Durango, I think about the viscosity-temperature relationship (went to 0W-40 in the RAM 1500 a few years ago, long story) or wanted something slightly more robust for the Durango because I want to tow with it, and while I'm sure they tested towing with 0W-20, it gives me piece of mind knowing that I got a bit of extra cushion there. As for the Toyota, if the owner drives it just as a commuter vehicle, then 0W-16 is plenty.
