CVT Fluid
If you have 60k or more miles on your Forester and haven’t changed your CVT/ Transmission fluids, I HIGHLY recommend doing so. My 2015 Forester 2.5i Touring is a couple miles shy of 76k and I checked my CVT fluid a couple months ago &it was like a reddish brown and I should’ve done it than but than today I had enough of the way it was riding so I changed it and now knowing it’s supposed to be GREEN, I should’ve done it awhile ago. But all this to say, my car now rides sooo much smoother since I changed the fluid.
