Motul every 10k for over 200k miles @486whp. Oil tests every other change. Now I do 5k or every 3 track events/races.
Motul X-clean efe for my 2016 WRX! 5w30. Hands down the best oil for the turbo FA20 engine.
In terms of oiling, get a sohn adapter so your apex seals aren't being lubricated with crankcase oil, and instead are injected with rotary-specific oil, like idemitsu.
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.
Oil and filter change, switched to motul 4100 15w50 (thanks Bernardo on the recomendation)
Subaru OEM oil is Idemitsu 0W-20. I currently use Idemitsu Zepro\* 0W-20, a high-moly formulation from the same manufacturer.
That's the wrong oil. You want the Idemitsu eco gold medalist advanced moly 0w-20, which is basically the same as Mazda oil(Idemitsu makes the mazda oil).
Been using motul 8100 eco
I use Motul 300V. No complaints.
