There are far too many factors to just spit out a figure. If you are serious about finding out when to change oil & filter send at least three samples to a lab for analysis. It is called trending and they can advise you , with your particular distances, temperatures, and habits, as to an oil change interval.
5,000 is a no brainer with any oil. 7,000 is very likely. 10,000 is also likely (or longer) but you MUST have backup from a lab to do so safely.
Keep in mind that the interval for warranty is 6 months or 5,000 miles regardless of what oil you use. You didn't state what year model you have or if it is in warranty or not, that doesn't help at all.
I say....pay attention boy!
