Hi everybody,
I took an oil sample and sent to BlackStone. Surprised with the result on the lead component in the oil (240 ppm), where should be zero.

From what a research it could be three things:
1) Bearing Wear (I use the car on track day, bellow more about car mods)
2) Usage on leaded fuel or Octane Booster (discarded, I run Shell unleaded and/or E85, no octane booster at all)
3) I run a Setrab Oil Cooler, maybe there is PB or tin component in the welds of the radiator. I try to contact Setrab with no luck yet.

I will appreciated your more knowledge comments about this finding.

My car is a NA 2016 FRS, with 23000 miles, several track day (25 weekend, more or less).
Normally I change Oil every 3000 miles, using Pennzoil Ultra Platinum.
Running E85 only on track weekends.
Non Catted header.
200 TW tires and BBK, some typical mods on suspension.
I drive very aggressive on the track, as DD drive I am super mild with the car, no burn out, drifting, street racing, etc.

Not that I am expecting the engine last 200K, but I am surprised with the result, I will re do the lab analysis in 2000 miles.
