Here is my latest UOA for my 2003 Honda S2000 with 40,157 mile OCI and 393,467 total miles on my car. I have an Amsoil dual remote bypass filter installed, as well as a prelube pump that pre-pressurizes the oil before I start the car. I've had this setup in my car since it was almost new.
As you can see the lead spiked up this time. I'm not sure exactly what caused this, but I suspect it was caused by a bad coil pack. I was traveling when one of my coil packs malfunctioned and I had to drive a few hundred miles with the check engine light to get home and replace it. Not a smart move, but I didn't have a choice. The car still runs great and besides the increased oil consumption, the car runs great.
