ZPOST - View Single Post - [Z4M] Blackstone Oil Report --2nd High Lead

Kgolf31 · 06-16-2013, 04:48 PM

6k miles might be too high.

I changed my first oil at 5k-ish and got around those numbers (21ppm Iron and 14ppm Lead)

Did it this time at 2800 mikes and sitting at 11ppm Iron and 8ppm Lead

Mine is heavily autocrossed and track.
