2025 Toyota 2.5L Engine Oil Viscosity Update.

[OVERKILL]

Probably 10k oil changes…

Yes, if only Toyota could figure out how to make an iOLM like every other car maker on the planet

I thought we were on the same page as to these engines NOT having electronic oil pumps? My wife has the A25A-FXS, not the FKS as stated in the video.

Does her motor have the supposedly electronic fuel pump?

Rare engine failure.
A25A-FKS.
(Same engine as RAV4).

A++

Here is another kid showing a seized A25A-FKS, towards the end he says that he suspects it was caused by the failed electric water pump.

Somehow the Fram filter will be blamed for it LOL.
And that is one clean engine for 125k

My son in law has Tacoma 2021 V6 and I'm switching it to ESP 0w-30, daughter has Rav4 2025 and it's getting ESP 0w-20 ever since factory oil is out. 5k miles OCIs with both.

No worries. Failure is unlikely.
Electronically controlled components. So it is probably sensors that fail, QC ?

The Crown reverted to a purely mechanical thermostat, with failure less likely

I have been going crazy trying to make a good choice of a 0w-16 oil for my new Toyota without using that world's greatest pyramid scheme $15.00 a quart oil. I called my local Toyota Dealer today 6/6/2025 where I purchased my SUV and got Jason, the service manager. I asked him directly if I could switch to a 0w-20 engine oil without Toyota corporate rejecting my warranty. He looked it up and said according to Toyota corporate I can permanently use 0w-20 or 5w-20 engine oil in my 2025 Rav4 SUV with no risk of causing warranty issues. I know it is not that big a difference really, but it makes me feel better, plus it opens up more choices. I thought maybe some people would like to know this.

I know this is against the rules here, but at least for a while, I decided to go with Liqui Moly Molygen 5w-20 oil. https://www.liqui-moly.com/en/us/molygen-new-generation-sae-5w-20-p003693.html#22152
