The consensus seems to be Rotella T6 (5w-40) with blue subaru filter

Due to it being winter and such and where you live OP, I am going to suggest the M1 0w40 over the rotella T-6 5w40 because of the cold. Both oils will do great in a subaru turbo motor, but the M1 0w40 has a few advantages to help in flow on start up. Both oils can be had at Walmart, the 0w40 in a 5 quart jug and the T-6 5w40 in a 4 quart jug.

So, M1 0w40 for the rest of winter then the T-6 5w40 for the summer if you want to switch. Use the blue OEM oil filter. In case you notice the T-6 5w40 is a universal diesel and gasoline spec'd oil. Has both the CJ-4 and SM ratings on the back of the bottle which can be used in both types of engines.

Hope this helps.

^^^^^^ notsomuch

The Winter temps at his location aren't like the Winter temps at your location.

T6 is perfect for all-season use. No need to use 0W40 for the cold months.

I've been running T6 for many years, and my winter conditions get down to -30f or lower... At that temp, finding an outlet is more important than the difference between a 5w and 0w oil!
