Here's a second analysis on the same oil run -
Last oil change was 11/26/07 at 88,267 miles.
Previous UOA is here - http://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Board=3&Number=1194277
A peek under the valve cover and the entire OCI history is here - http://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Board=48&Number=1196764
Overall, it seems like there is a lot to be pleased about. Wear rate seems nice and low and fairly even. It is interesting to watch the additive levels deplete. The puzzler though is why the calcium level would go up - sampling error perhaps?
