Engine oil OEM Subaru or Pentosin

I use Pentosin Pento HP II fully synthetic Euro Spec 5w-40 oil (made by Fuchs Oil in Germany). According to test data I have read it is a much better oil than the Mobil 1 oil. I believe that the 5w-40 oil provides greater protection against oil vaporization, as the OM642 can run at elevated temperatures leading to high oil temperatures, which tends to break down the oil sooner.

I have done all my oil changes myself since I bought my 2019 Subaru outback 2.5l new using 5w-30 and have never had issues! Just hit 120k ????

Getting 30mpgs in my ‘14 and been running 5w30 for years, smoother and quieter

No issues with 5w-30. Switched my 21 Crosstrek to it due to the summer months coming. Little dip in mpg but the engine runs smoother.

Either way I have the impression that the engine has a smoother sound and feel now, can this be possibile or it's just a placebo ?

They sell Subaru branded Idemitsu at the parts counter

After talking to a European mechanic. He said u need Germany oil for a German car. American oil is trash bc of the EPA regulations. He recommended Pentosin. The tick tock went away and I've been using it every oil change

Oil being dark is a good indicator that you have to do an oil change. However, you shouldn't wait until it changes color to do it. Clear oil doesn't necessarily mean you can keep going.

id put 17 at the okay point but any lower is not good - well my subaru would do about 18-17psi at idle so im sure alls fine

I avoid the 5 minute drive-thru places. One of them wanted over $100 for full synthetic on my Subaru Forester. Not worth the 5 minutes.
