New 2023 Corolla and 0W-8 oil

[OilUzer]

AI must have infiltrated ...

Smelling thin oil vapor can be dangerous!

It's unfortunate that this discussion often ends up centering around silly hyperbole and baseless speculation rather than a legitimate conversation based on science.

Could split the difference and use 0W-12.. if you must get a Toyota..

Use a 60 grade oil, after all, it will have the least wear as it will have the highest MOFT. Your engine will last considerably longer. Now if fuel economy is a concern you can use a 15W-40. But you will be giving up a considerable amount of engine life. This grade and any thinner grades are only CAFE related and should never be used unless you plan on selling you car before it gets to 50-60,000 miles. Using a 16 grade oil will only be a matter of time before your engine blows up.

^^^ CAFE ... holding engineers hostage since the 1980s.

I'd put 20W50 in it just to see what happens.

I would secretly drain the 0W8 and replace with 0W40.

You can even mix to make the CATERHAM blend.

That way you can keep your factory warranty but your car is protected.

Let's see what the owner's manual says:

Where's that 0W-8???

The 16 in 0W-16 indicates the viscosity characteristic of the oil when the oil is at high temperature. An oil with a higher viscosity (one with a higher value) may be better suited if the vehicle is operated at high speeds, or under extreme load conditions.

Nope...it does seem the latest recommend 0W-8, I'd just use the 16 and not worry...

Here's your 0w8 requirement.

Why? Because you quoted the wrong build date manual

And here's the oil spec performance requirement

Now someone on ToyotaNation is claiming 0w-16 "absorbs water" when you short-trip it in the winter time, and it's exclusive to 0w-16, not 0w-20, or heavier oils.

I'm guessing his rationale is because it's "watery thin" and like attracts like? Lol...

Here's your 0w8 requirement.

The part cut off at the end of the page is Toyota's standard OM statement saying that thicker oil is better suited or more severe use conditions. So Toyota is saying, even when they specify 0W-8, that a thicker oil can be used without issue.

OW-20 is the new 20W-50

Best comment!!

It's just standard crap writing from Toyota. But see in the circled, you can use a 0w16 if you can't find 0w8, but next oil change go back to 0w8, because by the time 10,000 miles have rolled around, you should have found some 0w-8 by then.

You also see in the maintenance manual, under more severe driving conditions, the OCI is now 5,000 miles instead of 10,000 miles.

That statement is there a to basically satisfy CAFE.

The manual printing ed's are weird, vary by every two months...

So I just bought a gas 2023 Corolla with the 2.0 as a commuter. Toyota calls for 0W-8 oil for this. I’m fairly certain they made a change within the last month or so from 0W-16. I do my own oil changes and sourcing OW-8 seems about impossible. The manual does say you can use 0W-16 but it must be changed to 0W-8 at the next change. My wife has a camry that calls for 0W-16 and I would like to use the same oil in both. I’m aware of the car care nuts videos stating that these dynsmic farce engines need the oil grades Toyota calls for, and I believe there are threads here disparaging his claims.

I’m all about giving my vehicles the best protection. Does the Corolla really need this pathetic water oil, or is it just for CAFE standards and to get .1 better MPG? I doubt they would have made a mechanical change mid-year that would necessitate the lighter grade, or would they? Should I go even heavier for both vehicles at 0W-20? At least then I’d have way more options.

Any comments would be appreciated.

0W-20 is proven for a decade with no issues. I would start out with 0W-20 for a while, and then perhaps try 5W-30 after that.

Why not do what Toyota says....They should know there cars...
