I was not "bragging" just adding data point. AT least on my 2008 LT it's 15K exactly, even if I idle a lot, I sometimes idle for hours at a time. I drive in some of the most brutal traffic in the nation for a living. All's I know is the change oil message comes on at 15K on my vehicle, maybe some others have a different program, but ON MY VEHICLE only, this is a FACT.

HAVE USED RED LINE FOR 20 YEARS .many miles 60,000 a year really i seldom change oi; just add a little more redline
have put 220,000 miles on most of em my last a chryl.pacifica went 213,000 with only 2 oilchanges and never a tune up. yep did put breaks on it a few times but change the oil every 3000, miles not a chance .

Natural oil although refined is made from crude containing dead plants and animals. When heated that oil produces ash which means it is self contaminating. Synthetics are not all created the same. Amsoil has been around the longest and the other companies have followed along as the demand has increased.
I use Amsoil 5w-30 and I have over 70,000 on my HHR 2.4. The engine runs as smooth as it did when I bought the car. I change it strictly by the OLI, but that mileage is typically a short change considering Amsoil users often go 25,000 with a filter change at 12,500.
Some natural oils on the market come from oil companies that own refineries, while other companies buy oil and "package" it to their specifications. If you wish to do some research, you can easily determine which are which. Synthetic oil is chemically engineered from a polymer base in a labratory. Each molecule is identically sized. This is an added benefit when considering a filter.
Do your research and you can make a sound decision. Mobil One is well thought of in the community, and I would say it's a close second to Amsoil.

As a long time driver, I have always had the "every 3 months or 3000 miles" systematically pounded into me.
Then I buy a 2007 HHR with a DIC that has an Oil Life Monitor. It tells me that the above statement is hogwash, that changing oil that often is a waste of precious resources, and that I should change my oil when they say so. So I bite.
Problem is, I am still a little leary. So my last oil change I switch to Valvolive Synthetic 5W-30. Figure the longer change intervals synthetic would be better. Manufacturers recommendation. Now, it taps a little on start up, sometimes I can here a very slight tap at idle. Oil level is fine. Car has 11,000 miles on the clock. Flushed the oil before switching to synthetic from conventional oil.
Does anyone have any ideas?

I ruined a Subaru engine with an engine flush. Appaerntly some of the crud it freed up got stuck in one of the lifters. Synthetic is great, but be very carefull with switching a high mileage engine, look for an oil with less detergency. The top of the line stuff will clean off varnish deposits that were keeping old oil seals from leaking.

You mentioned the tapping sound after the oil flush, Oil flushes are typically hard on motors, I would suspect your motor would not need a flush after that milage even if you never changed the oil. Some tapping is fine but should disapate over time and was probally caused due to the oil flush.
