So I went from a '14 to a '17EX recently and was checking out the maintenance schedules in the instruction manuals. Who doesn't read manuals for fun? 
Since I did all the maintenance on my '14 I figured I was all set, not THAT much has changed, right? So imagine my curiosity when I saw the oil change and filter replacement interval have both doubled to 8,000mi and 16,000mi, respectively. I always thought 4,000mi intervals were a little conservative especially since I was using synthetic anyway (Rotella T6 5w40 I think, the recommended 10w30 isn't really rated for southwest US summers), but since the job is so easy I didn't really mind doing it anyway.
Anyone know why they changed it up? I noticed the valve clearance checks are the same, for what it's worth.
