I just got my first oil analysis back as well and was going to post it and ask a question, I searched oil analysis and this thread came up. Even though this thread kind of changed from oil analysis to length of time between oil changes I still figured I'd post the question. We have same engine yet on a power wagon. same oil yet his interval of oil change mileage, I misread it and thought that was the mileage on the truck LOL, that is the mileage on my truck, not by oil interval change. I change my oil every 8,000 km or 5,000 miles. I did my oil analysis to get a baseline.Instead of posting my results which are almost identical to these results, my question is did anybody notice the somewhat high copper in his report, that might not be such a high number for the mileage on his truck, yet that is the exact same number of copper and Molly that is in my report, yet my engine only has 13,500 MI. My oil analysis was done by the amsoil labs not Blackstone, yet like I said the numbers are identical. After doing some research on that copper number from what I understand, which is very little lol when it comes to oil analysis on these types of metals. It usually means it's an additive that the oil you're using added or it's from the copper lines in the coolers or lastly possible bearing wear. Is that correct? Now my oil analysis company did point out that 85 copper parts per million did stick out for an engine with only 13,000 MI. Is that a number anybody would be worried about?
