Hey smart guys like @IrishLegend @Petza914 and @sburke91 I have a question. In these last few UOA Reports we see lead. Yes, very low levels. Why do we see it? I have a theory. I'd like your thoughts. Thank you.
Is Irish and Sburke using a product like Chevron Fuel System Cleaner prior to oil change?
Thank you.

Mileage/hours is how professionals manage risk related to lubrication failure in machinery and it is well documented in the literature. You will find people on all kinds/brands of car forums that say they did their own tests or they disagree for whatever reason and know better.
My data point regarding the lead comments: I use Driven Injector Defender (and +octane booster, I have both) on my last tank of gas that I burn up just before I do an oil change. My Speediagnostix lead levels are 0.

Hard to know how much that will change from here with more mileage. The metal and viscosity numbers look OK, but not superb. I prefer to see reports from at least 3,000 miles. It's possible that metal numbers may only go up 30%-50% more from these with the longer run which would still put all of them in single digits.

Latest UOA - Two samples 2019 and 2022
2006 C2S 3.8, 93k miles. Seems to be good. I had posted ealier on this thread a bit ago with a contaminated sample (multiple oils). This one is all Motul. I have changed to FR50 per you guys recommondation. Also had bore scope done. No scoring. My indy gave a clean bill of health. Love to hear your thoughts though!
