Here's the story: Since about 9xx miles I have been running Mobil 1 Synthetic (started with Tri-Synthetic forumla and have ended up with SuperSyn). In the winter I run 5W-30 and in the summer 10W-30. I've been running a 3k oil change interval after the car was broken in.
In the first oil analysis I was running 5W-30 and lead appeared a little high, no other bearing wear metals appear to be elevated. In the second oil analysis I was again running 5W-30 but lead is even high than before.
Here's the catch: Right before the first oil analysis I pulled the spark plugs, cleaned them off, rechecked the gap, and then reinstalled. When I installed the plugs I put a bit of anti-seize on the threads (probably too much).
What I'm wondering is:
1. Does anti-seize contain lead?
2. If so, is this lead starting to leach into the cylinder walls and then getting into the oil by the piston rings scrapping against it.
