Sign up for those annoying emails...
I believe the newer raptors come with synthetic in them from the dealership. My manual for my S Crew recommends an oil change every 7,500 miles.
I haven't taken mine in yet for an oil change, however I do know most dealers will offer you a coupon for a tire rotation and oil change if you sign up for their rarely read but received email lists. I know about every other month I get coupons. The last coupon I got is below.
