Just did an oil change on my 2007 xterra. It has ~189k on it. Ran 1qt of HPL EC for 6k miles to prepare to switch it fully to hpl premium passenger car oil at Dave's recommendation. I've historically used penzoil platinum high milage and PUP exclusively and changed it at anywhere from 5-12k miles so I wasn't expecting the cleaner to do a lot, I think my engine is pretty clean but I haven't been under the valve covers yet, not doing that till they leak. My commute is 70 miles interstate every day so I'm going to try to push this hpl beyond 15k and see what happens. I'll probably do a uoa at 10k and go from there. Overall though the filter from the previous change looks pretty clean.
