How frequently do you do it?
Pilot - again due to somewhat common symptoms, maybe every 30k. As I mentioned when you simply drain what comes out, that doesn't replace all the ATF, just a portion. A true "flush" actually involves draining and filling the system 3 times consecutively, but I said that the ATF is expensive so that procedure wastes a bunch of ATF (and $$$), so I'm just now figuring out how often I need to drain/fill, and I think that will be around 30k or so. It's not like that's the service interval from Honda, it's what I am noticing and in Pilot forums the symptoms seem to be common (and the resolution inexpensive).
Dexos D1G3 had a Sept. 1st, 2021 rollout date. So any oil after that date that wants to be D1G3, has to meet its specs by Sept. 1st and on.
Take published capacities with a grain of salt, they're not based on actual oil changes but instead theoretical capacities on CAD models.

Hmmm... now I have to decide if the Slickdealer in me is willing to wait and book up my 30th like that.
The 0W-20 and 5W-30 appear to be Dexos 2 Gen 2. I haven't looked up whether D2G2 has been tested to mitigate low-speed pre-initiation (LSPI), common in some US direct-injection engines, especially turbos (DIT).
I personally just changed the oil in my turbo Subie (FA20DIT) with Kirkland Signature 5W-30 Dexos 1 (ONE) Gen 3, which IS tested to mitigate LSPI.
When I researched this several years ago, the Dexos 2 (not gen 2) was spec'd by GM for their small turbos, but then they changed it to Dexos 1 due to LSPI. I would personally stick with D1G3 if you have a small turbo engine with direct injection. If you don't have direct injection, then D2G2 will likely be more robust.
- Oil filters are cheap from Walmart or Amazon
- Buy tool set with oil filter removal wrench
- Buy oil drain container. After about 3-4 oil change, you can dispose old oil at Walmart.
