All 3 of those metals are elevated in your sample report - you can draw your own conclusion.

So how long do I have? That's what I mean. So what if there is lead, copper, and iron in the sample, do I need to park the car and rebuild my motor right now? In 50 miles? In 50,000 miles? In a year? In ten years? There's no actionable information here because there's no way to determine how much service life the engine has left.



This sample was taken 15 months ago, so clearly it had more than 15 months of life left.
