Someone pointed this out to me today on the way home from work. I looked here: https://www.subaru.com/my-subaru/warranties-2011.html but didn't find a definitive answer. I think it's a wear item, but I've been wrong before!
I'm scheduled to have my oil change (7,500 miles) this Saturday and I was going to bring it up. If they're going to charge me though I'll just do it myself. Thoughts?
