I got an email promoting Subaru dealer services. In the email the claim was made that:
We recommend refilling with Genuine Subaru Oil at every oil change because it's the ONLY oil formulated specifically for your SUBARU BOXER® engine.

It's formulated with a unique blend of additives, detergents and modifiers specific for the lubrication needs of the SUBARU BOXER engine.
It reduces wear and cleans internal components to maximize engine life and maintain optimal fuel economy.3
Each batch is lab-tested over 10 different ways to help ensure consistent quality.

I would like to know who manufactures the oil and how it differs from other API SN and GF-5 oils. Also how this formulation meets specific needs of Subaru Boxer engines. I'd like to post the response on Bob is the Oil Guy.

This was the response:
Thank you for contacting Subaru of America, Inc. and providing me with the opportunity to assist you. I apologize for my delay in reaching out to you, as we are currently experiencing longer than normal response times.

Engine designs vary from one automotive manufacturer to another, each creating different internal conditions that require the right type of oil to protect against heat and friction. This is why we recommend servicing with Genuine Subaru Oil, because it’s the ONLY oil formulated specifically for your SUBARU BOXER® engine.

Here are some reason why we recommend using Genuine Subaru motor oil.

  • Engineered to clean and protect internal engine components between oil changes better than most leading aftermarket brands*
  • Formulated with a unique blend of additives, detergents, and modifiers specific for the lubrication needs of the SUBARU BOXER® engine
  • Reduces wear and cleans internal components to maximize engine life and maintain optimal fuel economy
  • Each batch is lab-tested over 10 different ways to help ensure consistent quality
If you are looking for additional technical information we would recommend speaking with your local authorized Subaru service center.

My evaluation of the response is that they claim their oil is better, but are keeping the reasons to themselves. I conclude that the oil is basic API SN and GL-5 oil.
An UOA is all you can do and compare results with others. If not find an “ aftermarket” that resembles what the UOA states. IMO
