Engine oil for 2023 Corolla Hybrid 1.8

0W16 is what is in the engine from the factory.

 

Suggested by WHO, exactly ??
You have a brand new car.
Did it really NOT come with an owners manual ??
REALLY ????

 

Toyota’s opinion is on the oil filler cap. And in the owners manual.

FWIW, regardless of their stance on 0W16 being the “correct” oil, 0W20, or even 5W20/5W30, would be fine too; they’re mostly chasing n’th degree mpg stats with super thin oil.

 

0W20 used to be the ridiculously thin oil, lol.

 

Stop the presses, excerpt from the US Owner's Manual (page 394):



(you can download pdf from Toyota Tech Info btw, often handier than the paper manual, you can search it easily)

 

Post a pic of the oil filler cap?

 

Check the title; that's the Multimedia Manual.

 

This little bit of text has gone through near COUNTLESS edits, going from second gen Prius onward:

SAE 0W-8 0W-16 0w-20 5W30 is the best choice for good fuel economy and good starting in cold weather. If SAE 0W-8 0W-16 0w-20 5W30 is not available, SAE 0W-16 0w-20 5w-20 10W30 oil may be used However, it must be replaced with SAE 0W-8 0W-16 0w-20 5W30 at the next oil change.

You get a little jaded...

 

I'd go with dealer recommendation; someone's got to bell this runaway cat.

 

FWIW, 2023 Prius Owner's Manual (US) is says 0W16.

 

Maybe there's a Corolla And a Corolla Hybrid manual?? I downloaded the former. Screengrab from bookmark tab;

 

Ok, see on Toyota Tech Info there's "corolla" and "corolla hv". I downloaded the former, and the latter (HV version) has this:



Maaaybe, the regular Toyota has the 2.0 liter engine, per 5th gen Prius?? Anyway, at least the oil cap and Owner's Manual are now agreeing, and the capacity at oil change is same and 3rd/4th gen Prius with the 1.8.

 

Dealer can be looking at their bottom line. 0w16 has not been out for long, and they could be paying more for it.

I've only noticed 0w16 in stores within the past couple of years. The first hint of 0w8 being in a Toyota outside of Japan was from photos at the Crown's reveal. Expect them all to to call for it eventually.

On the US site, the hybrid is a 1.8L, and the ICE model 2.0L. They dropped the base 1.8L ICE, and it sounds like the 2L gets better fuel economy than the old 1.8L. Changes have been made, beyond the new oil requirement.
