Good points here - the Fram Ultra should be able to handle two 5K mile OCI's .I usually change the oil filter every oil change but have done 2 OCI'S of 5k each on a Fram Ultra because Ford makes it a PITA to remove the belly shield on my cars. I used a Mityvac. I wouldn't do 2 OCI'S on an oil filter on a dirty (neglected) engine but otherwise I think it's fine using a high quality filter.
