High Zinc in Oil Sample, can somebody explain what does that mean?
What does high level of Zinc mean in my oil sample. I understand that its an oil additive, if I'm right, but why is it going up? What should I look for or keep an eye on?

Oil has 87000 miles on, but with every filter change I drain about 2 gallons and put 2 gallon of fresh. There is an mistake in last sample.... Lube change is NO, and filter change is YES.
Is this a good question?
