Mine is 1.8e. Means chg every 20k is normal? Cuz during services by toyota sc, no chg on auto transmission fluid at all till 40k. So i doubt is it too frequent to chg every 20k. I serviced in the workshop in bdr sunway, recommend by fr
Changing every 20K is overkill.
CVT is not running as same as ATF.
In fact the functionality mechanism of CVT is not as same as ordinary auto gear box with ATF.
Even with ATF, the recommended change interval mostly around 40K, (depended on the oil situation as well, sometimes after 20k, if the ATF oil show "blackish" then it is time to change disregard it is only 20k or less, but in normal condition with good quality oil, ATF should still look reddish after 20~30k, from my experience)
So far what I gather from the CVT oil changing need from the service personnel, it should able to last more than 60~80K.
Oil is changed when needed aka inspect the CVT oil quality to determine the need of change.
I cannot confirm the statement by service personnel is correct or not, just it is the answer given by both service personnel I had met.
