The 508 spec gets you better mpg and less dirty emissions. Gotta look at the bottle carefully. Mobil ESPX2 0w20 has that spec.
262k miles here on an M54B30 with 10k changes, Mobil 1, it's running great.
It should be fine. I use Mobil 1 and it's worked great.
SP certified oils have better LSPI protection than SN, and SP is what Subaru requires for this generation.
I use Mobil one in Canada when it goes on sale synthetic 0W20 10 k intervals 13 yr old corolla 1.8 and 15 yr old tundra 5.7 350 k and 320 km ; no oil consumption work great
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.
You must use Mobil 1 0W40!
Do her a favor a change the oil, with Valvoline Restore and Protect or Pennzoil Ultra platinum, it will quite down a little and it would be great for the car.
Expensive. I’d stick to Mobil 1 or Kirkland
Mobil 1 for me is like water in this car. I ran it for the longest time till I was tuned but switched over
