Engine oil PENNZOIL or MOTUL

Motul X-clean efe for my 2016 WRX! 5w30. Hands down the best oil for the turbo FA20 engine.

I've had good results from Blackstone with running Motul X-Clean EFE 5w30. It has a high HTHS value so it keeps it's viscosity over time, from what I understand.

Personally I use Motul 8100 Ecolite 0W-20.

Even though Amsoil produced the lowest wear numbers I'm using ultra platinum since I find that is what my car runs best on, engine is quieter than with amsoil or Mobil and velvety smooth.

In our 2003 1.8T Passat, we use; Pennzoil Platinum Full Synthetic High Mileage 5w-30. Changed every 4000 miles. Because we made the change early, we have not had and engine oil sludge problem. The Passat now has 205k miles.

Pennzoil Ultra Platinum is a crowd favorite and what I've been running in mine.

I’m using Pennzoil Euro 5W40.

Oil and filter change, switched to motul 4100 15w50 (thanks Bernardo on the recomendation)

Pennzoil Ultra Platinum has been doing well in my UOAs.

Been using motul 8100 eco
