Just got this report from the lab:
"Since this is only the second oil change for your 1000cc BMW engine (3,359 miles, first at 500 mi.), we expected wear metals to read high (Iron and Copper 2X average). They're from new parts wearing in, and chances are we'll see things drop over the next two or three oil changes. Usually we see high silicon too, from sealers, but that element is already low.
Universal averages show typical wear metals for this engine after about 1,900 miles on the oil. We'll watch the balance of metals to make sure there are no problems developing, but we think this is going to turn out to be an excellent engine for you."
I'm happy with that.
