I just changed the oil on my Mom's 2006 Jeep Commander with the 5.7L Hemi. The OCI was probably 5K Miles, not sure I forgot to log the miles last time I changed it. It was last changed Christmas day 2016 and she drives 30 miles each way to work 5 days a week with a lot of driving and trips on the weekends. The Jeep normally burns a lot of oil but I switched to Castrol Edge 5W-20 last time and it only used about a quart since Christmas. I put the same kind of Oil & Filter in and on this time. The marks on the media are from my tin snips, other than the damage I did to the filter it looks good.
