This report is from my moms 2006 Jeep Commander. 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. I put the same kind of Oil & Filter in and on this time. Filter was a Wix 51085.
