If the genuine / OEM CVTF is not available, then have a look at my following post in other thread:
If you will look in to the pictures, you will come to know that this CVTF also meets the CVTF-J4 criteria by Mitsubishi. In my opinion, you can use it.
Genuine / OEM Toyota CVTF-TC and CVTF-FE are available in the markets, but I still opted for this oil for my Vitz. AL HAM DU LILLAH working absolutely fine.
I hope. It helps. Thank you.
