Contrary to what is recommended by Subaru in regards to changing the CVT fluid, I had a Subaru mechanic tell me that changing it more often than recommended is a good thing as it helps avoid a CVT failure. I did some research and it appears that many seem to agree with him. And so...how often should I be changing out the fluid? I just purchased my first Subaru (Forester, Touring...2020) and am wondering what kind of schedule I should use for replacing the fluid. Suggestions??? Any other maintenance suggestions would be appreciated as well.
