What Oil and OCI do you use in your Subaru 3.6?

Inquisitory post is all. What oil do you use? What OCI? Filter?? I'll start.

2017 Outback 3.6 Limited 85k. Mobil 1 5-30 EP with Fram Ultra. I bought it new and this is the only oil/filter combo it has seen. Started with 1500 oil change IIRC then a 5k and 7k and eventual 10k. The 10K UOA was good so kept it there until COVID and retirement. I don't drive the same manner I did, so now doing 8k.

Thanks for sharing.

You're doing well. Nothing out of the ordinary with your two choices, I'd personally have no issue running a 3.6 on 5w-30/10k intervals. 8k is more than safe. So you're running an XG7317?

I'm using Ultra XG9688. Have used it from the first OCI to now.

I'm comfortable with what I've done with mine. I was bored and wondered what others are doing or have done with their Subaru 3.6's.

There aren't any worries yet, simple conversation. I have a CVT and so far so good. I did a drain/fill at 75k. Much better unit than the one I had on a Nissan Maxima. That CVT didn't have any mechanical issues at around 130K IIRC ... but was not anywhere near as smooth as the Subaru.
