Here's my first UOA from Blackstone for my 911 - 2006 C2S 3.8L Mobil 1 0W-40 with 3700 miles on the oil and roughly 1 year old. I welcome anyone's input. A concern with this engine is cylinder bore scoring. The aluminum and iron values are slightly concerning, but I will leave it to the experts to provide their two cents. Thanks very much.
FYI: After I drained the Mobil 1, I changed the oil from Mobil 1 0W-40 to Driven DT40 5W-40 and changed the oil filter to a Napa Gold filter with spin-on adapter from LN Engineering per the recommendation of Flat 6 Innovations. I'm going to send my next oil sample out to Blackstone and Speeddiagnostix for comparison
