Toyota oil is pretty good, actually. Lots of moly and a good additive package for overall protection.
Owner reviews for engine oil
I run Eneos 0w-20. Lots of people love Mobil1, if only because it is often on sale at WallyWorld.
Toyota Synthetic is made by Mobil. It’s basically Mobil 1.
I run amsoil Signature 0w20.
Personally I use Motul 8100 Ecolite 0W-20.
I run Liqui Moly 2044 Touring High Tech Diesel 15W-40 Motor Oil - 5 Liter Jug in mine since I bought it at 136k. Now at 164k and it purrs.
Prior to switching to this I ran Mobil Delvac 15w40 Dino for 100 k miles. LOA is identical both oils. I have run Delvac in DEtroits, Cats, and Volvo’s.
These days I do use T6 because I know the winters in south Texas aren't cold enough to worry about running anything lighter.
People like rotella because it’s a high zinc oil and subarus just like high zinc.
I run the Rottela 15w40 in my stock 05 Subaru Legacy GT (EJ255) and my mk4 supra turbo. Haven't had issues with the cats on the Subie, I do plan to remove them tho
