I just received my first oil analysis from Blackstone Labs for my '07 Z. Everything appears failrly good except the lead content is a bit high. Enclosed is a copy of the analysis. They suggest we keep an eye on the lead content in the oil because I track the car.

Does anyone have any experience knowing at what point the lead content in oil is unacceptable; point at which bearings need replacing?

I'd rather replace engine bearings and/or rebuild the engine rather than having to replace an entire engine.

IMO these analysis are just fuel for worry-warts (myself one of them). Change the oil and drive.

Blackstone will tell you. with each test just keep it up till you know whats happening as the mile add up

Blackstone also keeps your sample results on file so the following test results will be compared to prior results and the information provided in their analysis.

The comparison over time is more valuable than just a single snap shot.

Hard to get much out of one reading unless something really bad. Give it a couple of more tests. I am currently watching my titanium levels.

Heading to VIR for the NCM event. Will change oil upon return and see how well Mobil 1 5-30 holds up. Running solo Blue Group in my daily driver w/Hoosiers.
