I recently attended one of those lame "new subaru owner" parties that dealership throws? We had one of the salesrep talk about how to take care of our car and the subject of changing our own oil came up. He suggested that people use ONLY subaru oil filters because there is a "crush" gasket that is different on other cars? Is there really such a thing? Or is he blowing off steam? I normally purchase my filters at my local pep boys, but i haven't done an oil change on this car as of yet.
