As some of you may know, for the past 5 years I've been testing my Boxster's used oil before the annual winter storage oil change. The theory has been that perhaps regular oil testing might be able to detect IMS bearing issues, or other engine issues. So far nothing to report, but happy to have the results of my annual Porsche blood test looking 'normal', and wanted to share the data in hopes of informing more data-driven discussions. BTW the folks are Blackstone Labs are great to deal with - highly recommended.
