2025 Toyota Rav4 engine oil update, 5w-30

Probably calibrated for different regions. Best to not chance it. Might shear off of the drive shaft on the pump or something. Very sensitive ECM circuits.
LOL! I think it would probably affect the VVT, since that is regulated by oil pressure, oil flow and the car's ECM's. Somebody in an Internet video got this "electric oil pump" thing going a while back. I don't think that part is true.

So it is sarcasm, nice I like a good laugh.
The tolerances are to tight in the electric oil pump for US warranty purposes.
I have used in my 2.5 dynamic force Rav4 engine 0w-16 (free dealer changes), 0W-20 once because thats what I had, and 5W-30 now. It continues to motor down the road somehow, seemingly uncaring.

It was the care care nut guy who I remembered saying this, as if Toyota keeps a shelf of 64 different oil pump designs country specific. You know, the same company that literally has used the same dimension and design of spin on oil filter for every 4 cylinder engine since the 1980s and militantly streamlines their design process to have common parts across as many vehicles as possible...yes this company will make 64 variants of an engine, right?
No, VVT is moved by oil pressure but controlled by the ECU. The oil pressure is simply used as the motive force. If the ECU wants VVT to move it lets in or lets out more or less oil pressure into the VVT solenoid. If the oil pressure was too low to do this you would have other far worse problems. Some VVT models have been known to fail when the screen going into the solenoid gets plugged due to oil change neglect.
Its also not a electric oil pump. Its electrically controlled but chain driven. Meaning the ECU ramps it up or lowers the pressure based on conditions by changing the charge volume of the pump chamber, so the less has to be dumped through the pressure control valve and dumped back into the sump. If the electronics fail I imagine it just goes into full on and runs like a normal pump - pushing the extra out the pressure control valve, but I haven't been able to verify that specifically.
