The choice is your where you take it for service or maintenance. The oil life really is a algorithm that once reset will remind you that your oil life is at a particular percentage , there is no sensor that monitors yours oil life percentage remaining . If you use a full synthetic and a oem filter is shoot for the once a year change as your driving , from your post above , dictates time vs mileage .

For some dealership oil changes take the “ guess work “ out of anything problematic down there road
