yep, i know, and my dealer too. Even if it's ''within specs'', this is not normal, and will only get worse overtime with regular wera. Very dissapointed in Subaru's engines since them making the switch to 0-20W. We are on the 3rd engine in my wife's Impreza (less than 40 000km, all under warranty), and if I start too to have oil issue, they will probably lose 2 customers.
