4 months and 8,500 miles since oil change #1, Mobil synthetic 0W-20, Fram premium filter XG7317, 5.7 qts. Plastic around the filter that I cut out last time made this change even easier. Maintenance minder told me 15% oil life remained. Oil looked dirtier than the change at 4400 miles.
Going to change the air filter this week, rotate tires when I take it in to have dealer change transfer case oil in a couple thousand miles.
