I'm just wrapping up my fourth oci on my wife's 2015 Subaru Forester with and Valvoline Restore and Protect 0w-20, I would also hit it with Rislone engine treatment, for a more traditional cleaning action along side. Run for the manufacturer Recommended 5k oil change interval.
It's a manual (They consume less than a CVT) but my consumption went from just over 1qt per 1600mi, to one at in 4k. I can live with adding a quart per oil change interval.
Going forward, I think I'm going to drop the Rislone, who knows if it really added any improvement, but the engine as it sits is pretty clean, from what I can see.
