I`m just about up to 9000 miles on `06 foresterXT Turbo, and was wondering if that many miles would be enough for "break in". So I`m wondering what brand and type of motor oil would be a good choice for this vehicle? I have heard many points of view on this subject and I`m a little confused. Fire away Subaru geeks! And thanks in advance for your help and opinions...Cobalt:-\

Well, first off: Congratulations! Nice car, isn't it? I have one too.

 

My dealer and the local Impreza club all insist that Castrol RS 10W-60 is the best thing to use in Turbocharged Subarus. Since I have a pre-paid service contract on my Forester, that's the oil I'll be running.

 

If that's hard to get a hold of, Mobil 1 5W-50 would be good too. It would be my choice, before the Castrol.

 

If the 5W-50 stuff is hard to find, 5W-40 could do it too. If you can, then I would go for Mobil Delvac 1 5W-40. I am running this in my 85k mile Impreza and it has stopped the piston slap.

 

In short:

 

Shared 1st place

 

Castrol RS/TWS 10W60 / Mobil 1 5W-50

 

Mobil Delvac 1 5W-40

Mobil 1 5W-40

 

 

 

Any xW-30 oil would worry me, that turbo can get hot!

i run Castrol RS 10w-60 in my WRX

 

this oil is OEM for BMW M series

 

You can get it by the Liter at any BMW dealership.
