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

they only say you can do that with their Mazda-branded oil. That stuff tends to be expensive.
