Engine oil Mobil or MOTUL
Motul 5W-30.
I'm running 10w60 MOTUL 7100, I sit on the revs though, always Tach out!
I recommend Motul and I advise tou to never use RS8, it's a rebarded Xhina brand.
I was at LordCo recently and one of the workers was going off while i was looking at Motul.
Mobil1
Motul 8100 xcess for high mileage. I've had a few subies thrive on this stuff.
Owner of an often abused 250k+ mile 2002 Outback here. I use Mobil1 full synthetic 5W20. Runs like a top.
Porsche wanted you to use 0W-40 originally but now they recommend 5W-50 which is what Porsche sell for the 996 as their Classic oil for the 996. I’ve used Mobil 1 5W-50 for 3 years now, good pressure and next to nothing on the magnetic drain plug since so seems to be working. In my last change I’ve also added Ceratec on recommendation of another member of this sub and since have noticed the engine is a little quieter and get slightly better mpg so would recommend giving that a go if you are so inclined.
I will say I've done my last 3 oil changes with penzoil platinum and my engine rode rougher and louder than it did before with the Toyota oem oil. So this past time I tried mobil 1 and it's way quieter and rives smoother.
my valvetrain was always noisier when I used to run Mo1 0w40.
