I apologize in advance if this is a double post. I originally posted in the Euro oil subsection of the forum without scrolling down to find this subsection.
CONCERN: Lead level increase
How's it going everyone? I had a quick question in regards to a recent black stone report. So I've ran Motul for the past year and a half. The first and second change was on Motul's 8100 XClean 5w40. Any reason to be concerned about the rise in lead levels? I would assume the moly can contribute to the lead reading.
Here's a small breakdown on the maintenance aspect of the car (08 Nismo 350Z VQ35HR). It does see one to two track days a year. [4x20 min sessions for NASA AZ, ambient temps between 80s-100s]
-Magnetic oil drain plug; crush washer changed each time.
-OEM nissan air filters changed at 15k give or take (FR interval at 30k).
-HKS Superhybrid oil filter
Current oil/filter: Motul 300v 5w40 with HKS Superhybrid oil filter, new OEM filters.
Fuel: Chevron/Shell 91 octane; last tank was on Sunoco 100 octane to rule out a fuel issue. Car is tuned using the Uprev software.
Engine use: Mix of street/highway/track use
Mileage as of April: 39700 miles
Here are the three reports to show some trends.
