using a heavier oil weight has been an old trick to help with oil consumption in Subarus for a long time now. I used to use Rotella 5w40 (before the reformulation) in my old 04 Baja Turbo and that particular oil was the best to keep the oil burning down.
My regular since i think 2014 or so has been helix ultra 5w40 running in all my vehicles currently.

I run 0w30 in my F82 M4 as that's what BMW and Shell recommend.

I am using 15W40 Shell Oil for the last 8 years. No issues. 160k Kms on the Odometer
I have always used shell 10w-40 and did regular oil changes around 4-4.5k. Faced no issues what so ever, engine was still healthy, no oil consumption, almost same performance.
I run rotella T6 5w-40. Have for 120k miles and will for the next 120k
It's fine. Just not as good, and will not last as long as the OEM coolant. Wait 3 years or so, and then flush and get OEM. Better get something out of it. It's still compatible.
I changed the wiper blades from there last week and was not impressed either. He took off the old wiper and immediately put it into the new one's empty box. Fiddled with the new wiper, said it's not fitting and took both the old and new inside to get replacement.
