This looks very different than the G-Oil I had tested. The sample I sent came back after more than 10,000 miles with a Calcium level of 3580! And a much lower iron level.
 
We don't know the history or trending of this engine and whether or not the 7ppm iron/1k is normal or not.

GUT-Oil seems to show variable analysis results.

This is the first UOA I've done on this vehicle. It has had oil and filter changes every 5K miles since it was purchased new. I switched to synthetic oil at 60K miles if I remember correctly. Driving is mostly highway with some back roads. This is a daily driver pickup truck- very light duty.

Sample was taken with vacuum sample pump after about 25 minutes of highway driving.
