However, I do suspect that the Nickel and Tin may be indicative of some undesirable wear, but I am uncertain as to which components they are originating from. Originally, we had only intended to run this oil for 7500 miles, but the owner forgot to call me for a few months. At the time of service, the oil wasn't registering on the stick and appeared very dark upon draining. Also, I personally installed this oil and filter, so I am certain that this report is reflective of the real Mobil 1 AFE 0w-20. Lastly, I would like to thank buster for contributing to the cost of this UOA.
