Viscosity got a little low. Not a problem really unless you're racing on a hot day.
Molybdenum might be from assembly lube.
Normal break in metals and silicon. I changed my 2019 Tiguan out early for the same reason.
I like your choice of the slightly thicker, better Euro L 5w30. Funny that someone posted the other day about how a Jeep dealership accidentally put in the same Euro L 5w30 in his Jeep 2.0 turbo and he ran back to the dealership and made them change the oil again with "the right" HTHS 3.0 oil. (I think he should have just left the Euro L in there.)

That other poster went back because the oil is not SN+ , and he was worried about LSPI. NOT because the oil was too thick ...

The factory fill Idemitsu is probably designed to shear to a 20 grade from the moment the car is started. In all of the years that I have been following Subaru uoa's, I don't recall seeing any Subaru specced for 5W-30 come back with the factory fill staying as a 30 grade. And that goes back to the N/A EJ's.

Euro L has a low 1600 ppm calcium, as was repeatedly pointed out in the Jeep thread. Odds are very low any LSPI would surface. The Jeep 2.0L Turbo (alfa romeo) and this Subaru WRX 2.0 turbo are very unlikely to have a problem. If there is still concern, you can add a half bottle of Rislone 3X Concentrated Oil Supplement with Zinc Treatment or LM MOS2, as both are LSPI quenchers.

Being an STI, it still has the EJ25 which is port injected so it is not a TGDI. LSPI should not be an issue.
Euro L looks like a stout oil, I wouldnt worry using this oil.

You've never heard of Redline Break-In Additive? Some extra ZDDP is very common to use.
Or youv'e never heard of what engine builders have been doing for about 60 years.
Or Honda-Acura saying they like moly in new engines.
I thought all the 11,000 count posters knew that. Guess not.

Yep, I don't get it. If you had a special racing engine built or something on that order then I would go by what the builder recommended but for a mass assembly everyday passenger vehicle? No way.
Another member once made a remark about my post count. I haven't seen him here lately, or maybe I just have?

Yep, you beat me to it! No LSPI to worry about.

Thanks, I figured I would attempt to see how a thicker 5w30 handles the EJ. Planning on running a few OCI to let the break-in materials wash out and determine a base line.

I'm using Rotella's MV 5w-30 and it's very similar, had great results as well!

Forgive me, but what part of the LSPI (ringland killer) equation is directly tied to direct injection over port injection when the EJ25 is known to eat ringlands with observable LSPI in low speed high load conditions (can monitor it and it can't be tuned out)? Lower compression engines are going to lose their margin of safety in those low speed high load conditions...in my youth (2005 ish) I tried tuning that knock out and no amount of fuel or timing compensation would.....just had to adjust how to drive around those scenarios. I don't feel particularly concerned myself, knowing where that knock is, but I sure do feel a lot more comfortable knowing my oil shouldn't be contributing to it.

IIRC a lot of the ringland failures are attributed to high load / low rpm scenarios (WOT in too high of a gear at too low RPMs). Not nessicarily low speed preignition just insane pressure build up. A lot of times it was flooring it in 6th gear to pass on the highway without realizing (paying attention) they were sub 1500 RPMs.
Downshifting may have saved a lot of EJ25 lives.

I don't think I know enough about LSPI after reading this...
