The could go far longer than that, assuming average mileage per month. I put about 18,000 miles (three oil changes) apiece on many of those (including Kmart filters, which were thinly disguised Purolator Classics), with zero serious problems. There was very little to see in the media, except a few particles of carbon. That was all before the tearing issues surfaced.
