SP certified oils have better LSPI protection than SN, and SP is what Subaru requires for this generation.
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.
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.
I have a 2023 Civic Si.
I did every oil change at around 8k miles which is when my maintenance minder popped up, even though the dealer recommended every 5k. No issues ever, now at 46k miles.
Pennzoil Platinum Synthetic. My 1988 740 has near excellent compression at 245k og miles.
At the very least, make sure you're using quality oil like Mobil or Castrol or Pennzoil.
I use Pennzoil Platinum 5W-30 in my 2011 328ix (N51) I believe that is the recommended viscosity.
I use 5w-30 pennzoil ultra platinum full synthetic with the oem motor craft oil filter
I change my oil every 3k miles
-Guys I realized I haven't changed my oil for 60k kilometers how bad is it\n\n-My 20 year old Honda has a fairing loose how do I fix it
I dont know about the newer 1.5t in the crv's, but im getting rid of mine because of the oil dilution issue. Sent out an oil sample and it came back with 8.2% dilution on oil that had 2k miles on it with 0 idle time. All the technical service bulletins have been done and \"nothing\" is wrong with the car.
