My wife and I really rack up the miles on our vehicles. She hasn't had her new 2020 Impreza a full year and we ticked over 20k miles last week. Will probably be 25-20k miles by the time we hit the 1 year mark. Her driving is mountain back roads through Appalachia from the north of our county, to the middle of the county below us, so basically severe service.
Before she got t-boned, I would drain and fill the CVT on her 2018 Mirage every 30k miles, with paper filter changes every 15k miles. The filter on the Subaru CVT isn't accessible without breaking the transmission in half, but it does have drain and fill plugs.
Every thread I read online about CVT fluid changes in Subarus involve complexity with scan tools, temperature, shifting, etc. Is just doing a drain and fill on the level-est part of my driveway parking area not ok?
Like if I drain X number of quarts, why not put back in X quarts and call it a day? (assuming the drained oil drained, and fill oil were at the same temperature when comparing volume)
Dealer is insisting it is a lifetime fill, but I know that is a load of BS. At the same time, I really don't have the set up, time, or patience to do more than a drain and fill.
What are ya'll thoughts?
Would be using Genuine Subaru CVT fluid, and triple checking that it is the right one for this transmission.
