The sensors don't check oil quality...they know nothing of your oil status. All they do is calculate your change interval based on your driving habits and mileage since the last reset. So if you put an expensive synthetic oil in your engine, or a cheap conventional oil, your computer knows no difference.
If you're not the type to conduct UOAs and monitor your oil, I'd stick with the computer intervals when using high end oils, and stick with 5K intervals for low end oils. But that's just me.
