Toyota’s hybrid eCVTs (not an actually CVT though) are very much proven. 60K should be fine. Didn’t do the first eCVT fluid change our previous Toyota hybrid until 80K. 30K is overkill IMO.
Toyota's New Low Viscosity Transaxle Fluid
- Thread starter DirectRejection
- Start date
Continuing my ULV intvestigation, I wondered into Smothers Auto Parts today, across the street from Costco Gas Station, up in Sants Rosa, CA.
On the shelves, there were 20 or so quart bottles of different specialty transmission, transaxle fluids from Red Line, Aisin and Idemitsu. None of them were Genuine Toyota eTransaxle Fluid TE equivalent.
The manager came over and talked to me for a while, helping me geek out on fluids. This was truly exception customer service.
It turns out even Eneos also only offers factory mimicing, Group III basestock fluid in very expensive gallon containers.
The manager finally recommended that I go to this website called "Bob Is The Oil Guy."

Thank you all for excellent feedback.
I just had the rear differential fluid changed with Toyota Genuine eTransaxle Fluid TE.
The mechanic stated that the eCVT is sealed and is "lifetime fluid".
At 60k miles.
2024 Corolla Cross Hybrid.
At 90k miles, I am going to go badger the service departments at several Toyota dealerships. You have to beat it out of them.

There is a fill hole, half way up the side. Just suck out the fluid and measure it. Use a simple trans hand-Pump to pump in the same amount. Toyota has been saying “sealed transmission” and “lifetime fluid” for over 25 yrs.
This is greatly appreciated !!
I do not have jack stands, so no DIY.
But I will go back to my mechanic and show him your post.
Going with the Teal.
LOL.
I had to marinate on this for a while.
And conduct further research.

Genuine question from a 2023 Hybrid owner who is surprised it’s not WS fluid: are we at the point where folks are preferring to use WS fluid for its proven protection (Priuses with 200k miles before changes) ? As someone new to this whole oil obsession space hearing low viscosity makes me concerned.
Ok let's get specific.
Which transaxle do you have ?
The old hybrid transaxle or the new one ?
Driver's side doorjam.
Under the VIN.
At the bottom.
"A/TM: /PB10"
or possibly
"A/TM: /PA10"
etc.
This is the new transaxle with gear spacing designed for eTransaxle Fluid TE.
KV 100 3.3.
If it says
"A/TM /P810"
or something similar.
It is the old transaxle suitable for WS.
KV 100 6.2 ~.
Backwards compatibility is "on the table" going into the future.
As I stated elsewhere, Lexus apparently still uses WS everywhere, except for their all electric iterations.
There is some gray area.
But I would recommend a true fully synthetic fluid of whatever viscosity, which Toyota and Japanese aftermarket fluids are necessarily not.
