Here's my latest UOA on my '03 Honda S2000 with an Amsoil Dual Remote Bypass Filter and a prelube pump. Mostly highway miles, and no issues. I changed the oil and both filters when I took this UOA. The car runs great. This was a 41,093 mile OCI. The car currently has over 272,000 miles with no engine work (other than a valve adjustment).
I had a small leak from the adapter plate gasket, which I replaced during this oil change. The leak explains some of my oil consumption, although this F20C engine tends to burn some oil, which explains most of the makeup oil.
