Biggest benefit is walking into Wally and buying ESP 0w20 for $28. While your there grab a M1 filter for one stop shop.

While true, I mean on the aspect of how much greater performance.
Yes, next question.
Besides the MOFT headroom, ESP carries some of the most stringent approvals and specs. out there. Great base oil blend as well for engine and piston cleanliness among other benefits.

I’ve been debating going to ESP x2 0W-20 for the RXh and a Subaru I maintain. Currently, the Subaru - 2019 Ascent, FA24F gets ESP 5W-30, the RXh gets vanilla M1 5W-30. I have M1 Hybrid 0W-20 on deck for the next OCI.
My reasoning for ESP 0W-20? It meets API SP, and has Mercedes 229.72/Porsche C20/VW 508.00 and 509.00/dexosD approvals. It seems to pull above a “standard” ILSAC/D1 0W-20.
I’m using ESP 0w-30 in a range of domestic, asian, and euro vehicles I own or maintain. Hard to beat IMO.
0w-20 you need API SP or newest is SQ (backward compatible) and ILSAC GF-6a. On 0w-16 it's all the same but it will be ILSAC GF-6b, these are USA specs, I don't know about the JASO stuff.
It’s the standards for the ultra low viscosity oils likes 8 and 12.

Milky oil in pan.
#2 piston completely clean from coolant.
Guesses included failure of electronic temperature controls.
There were some quality control problems in certain other areas with early (~2018) A25A-FKS engines.
These showed up from time to time.
Per mechanics comments at YouTube.

Your link above seems not to work so thanks for the summary.
Anything can fail. Did it say how many miles?
Given the number of them out there, and the number over 200K already (including here on this board) I think there proven.
Sorry about that.

Scroll through his videos to find it.

It is an interesting video to watch.
He does a complete tear down of the engine.
Always scan the comments for nuggets from mechanics.
Looks like, at least from what I can tell, that the oil control rings might have been clogged on a few cylinders there, may have caused some of the bore scoring.
Probably 10k oil changes…
If only we knew exactly what the maintenance plan was.
I am always searching for a bulletproof engine with an airtight oil and OCI in play.
My guess is that the mess on some of those rings lead to the clearly illustrated scoring.
The coolant in the combustion chamber followed as evidenced by the clean piston and the "frappacino" in the oil pan.
One mechanic stated that ~ 2018's had electronic oil pump, electronic thermostat related failures.
Viscosity ?
Oil quality ?
Length of OCI ?
We can call this an outlier, pointing to more recent model years.
Input welcome, friends.
Did not mean to hijack.
Thought this was very relevant.
At least on this one, my 2025 A25A-FKS, it does have an electric water pump. The oil pump is not electric, but I think the oil temp is monitored, not even sure of that. I do know the engine coolant temp is up to operating temp FAST! I start the car in the garage, back out and head down the street, within 2-3 blocks the water temp is up to mid-range operating temp. I have been warned that if it ever starts to heat up, stop immediately, not 20 seconds from now, park, shut it off, and call a wrecker. It has something to do with the electric water pump. I think they can be damaged quickly from engine overheating from a failed electric water pump. I watched the video posted here, I think he said that engine had a little over 100,000 miles on it.
I am not sure why people insist on talking about an electronic or electric oil pump. Even if it were true it would have nothing to do with the engine's ability to tolerate low-viscosity oils without damage. Nothing.
Most variable oil pumps have just two settings, high and low. It isn't even that sophisticated but it can be prone to trouble since it introduces additional failure points. If the pump fails "high" then no damage, but if it fails "low" then that is a flashing CEL to immediately stop the engine.
Another instance of a dubious system to chase after ever decreasing fuel consumption returns.
