So this is my second oil sample and I'm a little worried about the Lead content. It didn't go up too much from the last oil change, only 1ppm, but still 24ppm is a little too high. The second oil sample was actually ran to 7300miles vice 6500miles. Luckily the copper looks to be low enough and that brings me a little comfort. This time I used the new BMW M Twin Power Turbo 10w-60 oil, but next time I'm definitely going to give Mobil or Redline's 0w-40 a try, and see how that goes. I will be running this new oil for only 4k before I make the switch then send another sample.
