What 0W-16 are you using?

I would just be worried about the variable volume oil pump. It was designed for 0w16 to be used, and for 0W20 to be used if absolutely necessary (and only for one oil change interval). I’m suspecting that it detects how much oil is being pumped, adapts to what the engine needs, and sends more. I don’t want the sensors to think oil has been sent in a certain volume when it hasn’t.

How do you say that after the non cafe constrained material from other markets with the exact same engine is posted before you commented?

The oil pump being designed for 0W16 theory has been debunked on here long ago. You’ll have to search to find the threads, but they are out there. It’s one of those things that was a moving target. First the oil pump was electric and calibrated specifically for 16. Then once it was discovered it was mechanical then it was a different oil pump based on the region. Then the ECU was calibrated differently. Every time something was debunked and new info was released then the goal post shifted. Bottom line is that it is not designed specifically for 16, but it is designed to allow for the use of 16. Big difference. Here is some additional info on Toyota engines.

The Internet garbage that just won't die, and here it is again in all the glory.

I was waiting for the part about the drive gear in danger of being sheared off by the thicker oil.

List of oils I’ve used between current and previous Toyotas spec’ing 0W16.

Toyota Genuine Motor Oil 0W16
Valvoline Advanced 0W16
Pennzoil Platinum 0W16
Mobil1 AFE 0W16
Pennzoil Platinum 0W20

I cannot tell the difference between any of them to be honest. Maybe one is louder than the other and I just didn’t notice. The question is does it actually matter?

Next up is Castrol Edge 0W20 cause it was on sale awhile back. I just buy whatever is readily available and/or on sale at the time. Some times rebates play into it. But sound never does.

Most of the 0W16's are fairly similar in viscosity, but I have noticed that some are creeping up into the 0W20 range. Yes, I'm looking at you, Amsoil SS.

The one I posted was a uk manual and it showed up to 15w-40 and that's not wild. The prior gen allowed 0w-20 to 20w-50 so the same 3 thicker grade allowance. But a 30 grade is plenty thick and 40 grade is unnecessary unless being driven hard. Try something like m1 esp 0w-30, pp euro L 5w-30 or just m1/castrol EP 5w-30.
 
Curious, is there a such thing as Variable Volume Oil Pump? I always hear about PD Pump ... but I typically don't visit 0W-16 or thinner threads.

I googled the Australian manual for my wife's 23 rav4 after I saw your Pic. It only mentions up to 10W30. Japan definitely isn't changing bearing clearances for different countries.

Im an Amsoil user, so I'll go for the SS

Probably a revision or something. That 2023 engine hasn't changed since it debuted in 2017. Even so a 30 grade is still thick enough for it. I posted a thread of the latest yaris hybrid using the latest engine architecture which is a bit newer than yours and also uses 0w-8 but allows 16, 20, and 30 grade so also a 3 grade thicker allowance and that seems to be the real limit.

Honestly, I think I would be running a 5w30 myself if I owned a RAV4. I recently rented one for a 3- day vacation and really liked it. I did some research on the vehicle and I wasn't too comfortable with the 0w16 spec'd oil, just me.

Because you got permission from Australian owner's manual???

No “permission” is needed. Grades listed in the manual are recommendations. As long as a minimum HT/HS is maintained you can use any grade as far as that goes. Other oil properties apply (such as SAPS level) but a higher grade of oil does not require permission.

Toyota's manuals are persnickety, and they are pushing the use of the 0W16 oils. Nobody has yet to show that thinner oils have led to engine failure or engine damage. Taking anything from a manual distributed on the other side of the planet over what you got with your car makes is illogical. Like you, I am driving older cars, but if I were to drop $70k on a spanking new Land Cruiser - which I may -- you can bet your bottom dollar that I will be following the owner's manual to the letter.... except that I will go for shorter OCI's.
