Specifically for a reasonably high strung Forester XT basically a detuned STI motor.
Had a local guy put in Amsoil 10w30 ATM, seemed ok at first but then the engine got a little rougher as time rolled on.
It did have a turbo issue though, didn't really affect performance just a leaky exhaust side seal. So I burned some oil in 5k miles. Replaced with Mobil 1 EP & Castrol Syntec as needed. maybe 3/4 quart each and both 5w30.
Going to change it myself now and take a sample. I bought Castrol Edge 5w30 but was wondering if Mobil 1 EP 5w30 would be the better thing to get. I also was going to fall back on my beloved GC Ow30 but they didn't have enough.
So who else runs a Subaru in here that has been down this path?
Edit:Turbo was replaced so it burns no oil now.
