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?


You should tell them how much oil you add between changes, and they take that into account when they do the analysis.

I've used them once, a few years back, and plan on sending a sample again real soon. I'd say the results are a pretty good indicator, especially if they find traces of anti-freeze in the oil.

Twenty bucks, how can you go wrong?

C/YA!
