this profile is like the definition of mobil's "aunt millie" test. judging from that test, if warranty considerations were not an issue, i would say pick your fav synth and run it for 10k regardless of time (or put a 5 year limit on it). there are hard numbers in the aunt millie test to back up this view.
since warranty is a concern, i would take the car to walmart every 7500 (what, they are gonna measure your trips?) or whatever time period is used for the regular service interval, and use either the walmart synth or whatever SM grade oil brand you prefer, and keep your reciepts. at 7500 OCI, any SM grade oil should handle this.
