My girlfriend recently purchased a 2013 Jeep Grand Cherokee with the V6 and she is really bad about doing her oil changes on time so I thought I would switch it over to Mobil 1 extended 5w30 and throw a fram Ultra on it so I would plan on changing every 10k but would feel comfortable if she went 15k cause she forgot to tell me it was due. However when I went to walmart to purchase said oil filter I realized her Jeep is cartridge style and they dont make a fram ultra, what are some other good filters I could feel comfortable going that long of an OCI. Thanks in advance.
