Thats all I wonder... Mobile is known to suck for our cars, it might change with different lines they make, but why stress it when T5/6 is widely accepted?
Because RT6 is quite arguably too thick for an N/A Subaru, RT5 is lousy in the cold, and because people love to use brand as a bad heuristic for quality, when in reality the type of oil is much more important than the brand.

I prefer information to wives tales. Mobil is not known to suck in "our" cars. Resource conserving GF-3 and GF-4 5w30 oils are known to suck in turbocharged Subaru applications. Since this forum serves owners of both turbo and N/A cars, I figured the information would be helpful. Especially since the EZ and FA/FB engines share a great many design elements.
