A few pictures of a MO-285 Mopar filter after a 15k OCI in a Cummins 6.7 with 153k miles. I've opened up a few already with the same OCI and they've all looked the same. I know that I've read a few threads where a few people have suggested that these shouldn't be run this long but, I don't agree with them at all. UOA's have also come back excellent with this filter so there's no reason to not to follow Cummins 15k OCI recommendation.
