My wife\u2019s 2012 Impreza is at 195k miles and I switched it to 0w-30 and then 5w-30 due to oil consumption. Was burning a quart every 1K miles on 0w-20, burns half that on 5w-30. I\u2019m actually considering going thicker.

Pros: burns half that
Cons: oil consumption
Mileage: 195000 km

The dealership here itself was using 5w-30 as the default for oil changes even though 0w-20 is stamped on the filler cap. After checking myself that Subaru said that would be OK, I started using it too for my own changes just to avoid flipping back and forth -- though I have no idea if that would be a problem. In any case, the Forester seems happy, even if the mileage may have dipped slightly.

Pros: Forester seems happy
Cons: mileage may have dipped

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
