I took this oil sample primarily to determine if coolant was present in the oil. The coolant has ever so slowly dropped steadily since new. Dealer pressure tested the cooling system this week and found no leaks. Blackstone had a "?" in antifreeze column due to high potassium. However, on tdiclub.com mutiple other UOA's on the new common rail engine show high potassium for the first couple changes. I will be changing the oil this weekend with Castrol SLX Professional LL03 to flush out the wear metals, then go 8-10K on future changes. Aluminum, copper, potassium, and silicon flagged for high.
