This run (so far) was from early May to a few days ago. I plan to leave it in for a few more months (I guess...I'm anxious to check the magnetic plug). I will update when I finish the OCI. This sample was to check for any abnormal wear readings. Many of you have heard about the Coyote ticking noises; well mine does not tick at all. However, since I put this oil in, it has had three episodes of valve-train clatter. Each time the clatter was heard, it started roughly 30-45 seconds after a "cold" start and it was plenty loud. The first time was the very first start after installing this oil and filter (Fram Ultra), then again in the summer and once more just recently. In each case, it continued until I shut it off; when restarted seconds later, it was quiet. It never made a noise during the previous two OCIs. This OCI does include a bunch of very cold weather starts, but the previous OCI includes all of last winter (many brutally cold weather starts). No make-up oil added during either OCI. Both times, the oil was down a few ounces. This 5W-30 is dexos1 Gen 2 Edit: this OCI, the oil was down just a few ounces. I believe the last time it was down perhaps 16 ounces. I'm far from home and can't look at my records at the moment.
