So drain at ambient temp (car sitting over night) and fill with same volume of fluid sitting next to car overnight. Same temperature = same expansion.

I can see how that should work, Im just sharing what the service manual states!
If there were no issues with the transmission prior to drain, then drain and fill with the same volume will be acceptable. However, if the tranny was underfilled at the factory you would not know. Example: I did a drain and fill on our 17 OB with the 580 tranny last December. I drained ~4.75 quarts of CVT fluid and filled with ~5.4 quarts of CVT while the temperature was ~95 deg F. I believe there is some flexibility with the volumes. If I would have just added the drained quantity back, it would have been ~0.7 quart short. No difference in driveability however.
I had Subaru Dealership perform 60K Service on my 2020 Forester Premium. They recommended also changing CVT ($399) & Differential fluids ($189) but I declined since I don't off road or drive in dusty conditions. Plus I replaced original battery ($349) which took Service Bill over $1K. I will have both changed @ 66K or in 6 more months for a piece of mind. Remember reading that Subaru in past said CVT is for life of vehicle? Guess not anymore. I don't tow so I should safely make it another 6K before change out.
Factory service intervals don’t determine owner compliance; if the manual said you had to change the oil every 800 miles or every other Tuesday, would you? Also, even if they were to require 60k CVT changes, not every owner is going to be interested in or able to afford the service.
If you know more frequent service is required, or it makes you feel better to do so, go right ahead regardless of what the manual recommends.
I would change it now at 30k and not wait until 60k.
Here is what drained from my Toyota at only 22k miles.

Agreed. I would drop the pan at the first year or 10k to inspect and clean the magnet, and again at 30k. Once the transmission is broken in, and the fluid / system is clean, you are probably close to "lifetime" fluid status.
There is no such thing as lifetime fill, especially on BITOG
You probably should've had the CVT fluid done. The differentials are less critical, but still probably worth doing. If you just want to wait another 6k, that's fine, but the CVT should still be done regularly.
The diffs you can probably do once and then never again, while the CVT should have a fluid change at least every 30-60k.
Subaru CVT's require a scan tool and a flat surface to properly change the fluid.
Opinions vary, but that seems a bit of a stretch on a relatively new vehicle regardless of make/model. Suppose that would fall inline with oil/filter changes every 500 miles, adjusting tire psi every other day, etc. I'm all for long term preventive maintenance, but I do like to actually drive/enjoy a vehicle and not live under it, bwahaha.
@Spro4Life: I don't know if this applies to all (most?) automatic transmissions but the majority of wear in the Ford 4r70w/4r75e family occurs in the first 10-15 thousand miles from new, so it's recommended to drop the pan and clean the magnets and replace the filter around that time. The filter should really never need changing again and the fluid changes can be extended to 50-60 thousand at that point.
Went to do the CVT 100K Km/60K mile maintenance in our nelwy acquired 2021 X-trek. Called the local Subaru stealership, who said they only sell the apparenlty platinum-infused, Mars procured, ultra-grade, Subby-only CVT3 fluid in 20L/5gal pails in Canada. How much? ALL OF IT. $795.00, for me.
So I said OK, how much to have you do it? $500 he said. So I told 'em: I didn't want MY fluid changed, I wanted the cars fluid changed.
So he pulls me aside and wispered (as if we were trading state secrets) that I could TRY buying Subaru CVT fluid in the qt online, or that (looking around to see if anyone was listening), there might be "off-brands' that could work. But I didn't hear that from him.
SO, after much research, including emailing the TECH departments at both Subby Canada and AMSIOIL, I dit it myself....and you'll NEVER guess how much it cost - and how long it took me.
Take a gander at this - and learn ALL the SECRETS.

How many threads are you going to spam with this repeat post? Four threads so far it seems.
AMSIOIL? "and learn ALL the SECRETS"? Obviously trying to promote your YouTube channel and generate revenue.

If you didn't want to pay the premium for Amsoil, Valvoline MaxLife ATF is available in Walmart (Canada) for $50 / 5L all day long, delivered. I've used both and would certainly use either one before paying the royalties of Nissan or Subaru.
What's the big deal? The video contributes knowledge to this thread.
What knowledge does that video contribute to the thread?
I mean how many other CVT-3 videos are there on YouTube? That’s only the 2nd one I’ve seen. I find it valuable because it validates Amsoil’s compatibility with CVT-3. Also runs down how to accomplish it.
Okay sure.
