Hi all!! So I'm getting ready to change my oil. And my plan was to use Mobile 1 synthetic. But recently iv read that Mobile 1 and turbos don't get along very well. Long story short it degrades to W20 really fast?
Well I was wondering what would be the best to use? And what other people have been using?
Right now I'm running an almost stock 06 wrx. Only thing I have on it so far is a Cobb catback.

You'll be fine with most anything. I would just avoid the 5w30 M1 and Royal Purple. You don't require a synthetic. I used Castrol GTX until a few years ago when I started getting into a bigger build and I still use it on my gf's WRX.
Motul is what a lot of shops seem to love, however it's pretty expensive.

My understanding is the same. M-1 is fine. It's just the 5w30 that's the problem. Actually most of the energy conserving (5w30's) oils are good to shy away from with the Subies. My .02

I dont think you have anything to worry about switching at 115k miles on it but to each their own.

Shell Rotella is cost effective and a good oil. Amsoil is a good oil but you pay a premium for it. I get it at cost and it is still very expensive IMO when compared to other quality oil companies. I run Castrol GTX in all of my NA vehicles but in the STi i run a full synth.
