I checked out their site.This sounds like a worthwhile test, especially if you're considering keeping a high mileage Zu for a lot longer and putting money into modifications. I wonder how the test results would be affected for those of us adding a qt. of oil every 1,000 miles or so.

Has anyone else heard of this lab and how accurate an indicator they are of potential problems?
