Blackstone Lab's average on my cdi is 50. They flagged it when it "spiked" to 107, which I concluded was because of me using Mobil 1 esp oil. Since I switched to Mobil 1 European Blend, the iron level came down to 83 on my last oil analysis.Just like with everything in this life, you never have solid borders.
I was sending oil samples to Blackstone Lab.
For them iron at 30 is red flag.
Send the question to your guys and see what they answer?
Also with using the esp oil, my copper spiked to 6, which the average is 3. My last oil analysis it was at 4.
