Lots of speculation and very few facts presented here. I think you could go 12 years/14K with the right filter. How about 5 years for an OCI backed by UOA?

Or, how about 9 years and 6300 miles with Used Oil Analysis? Here you go:

My two cents worth is that the OP is attempting to determine when it is advisable to change oil/filter; and my answer is to do whatever lets you sleep at night, perhaps take an oil sample for analization when you feel its time for change and see what the test lab says....Until then, everything that anyone says is speculation.
There are several filters such as Fram Ultra, Royal Purple, Amsoil Ea, and many others that are full synthetic media and designed to go 15-20K miles; and the filters don't have clocks built in and are unaware of time.
Of course there are BITOGERS who think you should change oil/filter every year even if the oil has only 200 miles on it. I'm not one of them....I do regular UOA and go by the test lab results and pay no attention to armchair tribologists.
Peace.
