The only way to tell when you "should" be doing oil changes is by doing a UOA every single change.

From what I've read, many people believe that the engineers that designed this system is pretty much an ongoing, dynamic UOA that changes along with your driving habits.
Of course, many believe it's ******** as well, haha. My friend changes his oil every 3,000 miles whether the OLM reads 10% or 90%.
Me? I'm going to see how the OLM reads my own driving habits first. If it routinely has me changing the oil every 2-4000 miles, I may lose faith in it, especially if a UOA proves I could be going longer.
