My first oil change was yesterday at 2700 miles. The oil and filter were very dirty. The OLM read 62%. I replaced with Pennzoil Ultra 5W30 and used the AC Delco OEM replacement filter. In other posts I had been complaining about noisy and/or ticking motor. After driving for awhile, maybe 15 miles, and shutting motor off several times and re-starting and listening to idle I will say that the noise level has gone down quite a bit, maybe 25% (IMHO). In the 50 years I have been driving and the few dozen vehicles I have owned almost always after changing oil motors "seem" to run better and quieter. Fact!
See you in about 6000 more miles.
