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.

Pros: keep oil burning down

Vehicle: Subaru

SP certified oils have better LSPI protection than SN, and SP is what Subaru requires for this generation.

Pros: better LSPI protection

Vehicle: Subaru

I use PUP 0w20 in mine. Lots of tests and UOA show that Pennzoil Ultra Platinum is the best non-boutique oil you can buy. But honestly any top shelf oil will work. 5k km intervals are more important than brand with a turbo engine.

Pros: best non-boutique oil

Vehicle: Toyota

Mileage: 5000 km

Ive used T6 with good results. The major drawback with T6 is foaming, it's less than great in that regards.

Pros: good results

Cons: foaming

BMW switched from Castrol to Penzoil years ago...but both cause oil starvation in The S65 motor

Cons: cause oil starvation
