Engine oil PENNZOIL or Motorcraft

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.

Pennzoil Platinum Synthetic. My 1988 740 has near excellent compression at 245k og miles.

Motorcraft 100% Pure Synthetic Oil and motorcraft filter.

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

I've been using Penzoil ultra platinum full synthetic 0w-20, though it does burn sometimes a quart every oil change.

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