Long-time lurker. I have been searching for an oil for my turbo engine car made after 2020 (Subaru 2.4L). My owner's manual spec's API SN+ ILSAC-GF6A, but given my engine's known risk factors, I wanted to find an oil that is spec'd for greater protection. I recall reading discussions about oil that has oem approvals, and after some searching found Castrol Edge LL IV 0W-20. I'm still under warranty - I will be using an oil with API approval and the weight spec'd in my US owner's manual.

I reached out to Castrol customer service and received the reply below. I believe I have a kit from OAI in the garage. If I do, I might run a used oil analysis or VOA. I thought I would pass along the info to anyone who might be interested.

"Castrol EDGE Euro 0W-20 M replaces and consolidates the following three existing products:
Castrol EDGE Euro 0W-20 LL IV

I've looked at alternatives such as Mobil 1 ESP X2 (API SL) and Motul 8100 Ecoclean (MB 229.72, LL-17 FR+, Jaguar, API SP/SQ).

I ran one used oil analysis with Motul 8100 Ecoclean, wear was fine. Motul is only mail-order for me, and I'd like to find something I could buy in a store.
 
Can you find it easily/cheaply? It certainly seems to have a plethora of approvals so I'd say send it. Or just run the Mobil 1 ESP X2 0W-20. Don't know why you claim it to be API SL, the jug that has been in my garage for the past 2 years is API SP.

Technically, ESP 0w-20 is not API SP/GF-6. Just meets the SP engine test requirements. Increased additive levels prevent it from being fully within API specs. Doesn’t make it any less good; in fact, it’s exceptional, and I’ve used it myself. But it doesn’t have the starburst or donut the OP is looking for.

What do you expect the used oil analysis or VOA to tell you in regards to your other questions? If you're intent on sticking to the owner's manual recommendations (note they aren't requirements) then it is a bit black and white based on what's printed on the containers.

Thank you.

Yes, it's listed as API SL on the the API directory. According to the PDS, meets API SL and "SP engine test requirements".

Ah yes, that is correct. Still puzzled why the OP is looking for increased protection from an oil based on manual RECOMMENDATION because he/she is still in warranty and HAS to have API SN+/ILSAC GF6A. However, OP does acknowledge risk factors in said engine driving his/her desire for more protection. Take off the bubble wrap and get a higher visc. oil with an HTHS of 3.5 or greater. Several 0W-30 oils will provide this protection and pose ZERO issues for the warranty period (and far beyond). Do you also drive the exact speed limit, never above?

I have a 2025 Outback Wilderness with the same engine and I would strongly recommend you use any of the following:

Pennzoil Ultra Platinum 0W20
Castrol EDGE Extended Performance 0w20
Mobil 1 ESP 0W20

It is approved for usage per ExxonMobil, see thread linked below:

These Subaru’s love a 30 grade. Plus they’re known fuel dilutors. I personally use ESP 0W-30 in an 18 Outback, 13 Forester, 24 Crosstrek and 19 Outback. Also note oil consumption can be a problem and I cleared mine up completely with Valvoline Restore and Protect. It may be wise to run that full time to avoid ever dealing with it.

I contacted Subaru at the corporate level in recent months regarding the usage of something other than 0W20 while under warranty and they were adamant about using that specific grade in this specific engine. Based on what the OP has stated I would not suggest using any 0w30 for their purposes.

FWIW the Subaru corporate reps I have been in contact with did not specify any mandate regarding anything other than the usage of the 0W20 grade motor oil. If you want to go strictly by the book then yes I would use an API/ILSAC approved 0w20 such as PUP and/or Castrol EDGE Extended Performance, both of which have proven to produce good results in this specific engine.

Otherwise Mobil 1 ESP 0W20 is promising and I personally will be using it in this engine over my next two oil change intervals.

Well, I would fully expect them to tow the corporate line, which I'm sure is rooted in CAFE numbers and fuel economy. Especially absent of any mandate, TSB, or recommendation suggesting otherwise. I guess I'm just an outlier and would want something a bit more "protective" so I could be more confident making it well past just the warranty period. Wonder what the owner's manuals in other countries recommends?

Just to be clear I'm not disagreeing with you at all, in fact I'm on board with your sentiments and have discussed them ad nauseam for over a decade on this website, SubaruOutback.org, and others. A certain YouTuber recently posted a video about how a severely neglected engine in a late model Subaru was destroyed after 80,000 miles or so. I'm going to try to play by the rules as best I can because I don't want to be that guy 👍

For my part I purchased the 8-year / 120,000 mile warranty with my 2025 Outback and I will not be keeping the vehicle beyond that warranty's expiration.

That is the usual response from corporate. Although someone did post an email from corporate stating 0W-30 was fine as it was a recommendation in Japan. As with anything it’s dealer dependent. A dishonest dealer could attempt a lot of things that won’t fly in arbitration.

On a side note the oil cooling is much better on the turbo 2.4 than the n/a 2.5 like below.

I know about the email you're referring to and made reference to it in my contacts with Subaru of America corporate reps and as of this summer they are not on board with it. YMMV
 
As a corporate statement they cannot recommend any grade not used to obtain EPA fuel economy ratings. In fact they are required to actively discourage the use of any other grade.

But that doesn’t mean it is a warranty requirement nor does it mean it’s a mechanical or technical requirement. Warranty is predicated on an oil that causes damage, and despite the required dire language in the owner’s manual it’s still a recommendation.

Historically Subaru engines have not had the best track record in terms of their cooling systems. The old 3.0L H6 required 91 octane to mitigate its issues even though it was naturally aspirated.

Many wonder why Subaru's standard oil change interval is only 6,000 miles. I would submit to you it is because the 2.4L turbo engine will typically shear an oil out of grade during a standard OCI and the non-turbo 2.5L might just cook the oil into having issues due to insufficient cooling.

I am only a spelling expurt on BITOG so don't look to me for in-depth details in terms of technical breakdowns and analysis.
 
I have been using Pennzoil Ultra Platinum 5w-30 and it works fine, though I will use 0w-20 Pennzoil Ultra Platinum over the up coming winter temps as they fall well below zero here.
 
Even though the non turbo FB series engine does not have oil cooler like your FA series engine, it does maintain coolant temperature very well even with elevated oil temps from towing etc. In normal driving the coolant temperature fluctuates very little compared to the EJ and EZ engines. The FB/FA engines have 85 percent of the coolant from radiator going directly to the cylinder heads, 15 percent to the engine block. The result is a more uniform cooling, a head gasket that is not constantly thermally stressed like the EJ engine where coolant has to flow to the heads after already cooling the block.

Picture from an FB25 engine towing 1500 lbs up I-70 to Eisenhower tunnel. Even with 259 degree oil, coolant temp was in control. Cooling fans still able to pull coolant from 211 to 200 at that oil temperature. And average mpg started trip at bottom of hill. Most tanks 21-24 mpg for those liking that information

Yep, Mobil recommends it for our Carnival too. It’s actually like the second or third recommendation on the list, however they organize their recommendations.

This is one of the risk factors I was referring to.

That is what I am doing in my vehicle. I prefer to use oils that meet my owner's manual requirements and carry manufacturer approvals with rigorous wear testing requirements.

Many wonder why Subaru's standard oil change interval is only 6,000 miles. I would submit to you it is because the 2.4L turbo engine will typically shear an oil out of grade during a standard OCI and the non-turbo 2.5L might just cook the oil into having issues due to insufficient cooling.
I ran two used oil analysis on my vehicle, 5.75k and 5.9k intervals, 100 C kinematic viscosities tested at 7.0 and 6.7 cSt. The oil started at 8.0 cSt per the oil's PDS.
