I was talking with my dad about this. Cadillacs get a Mobil 1 factory fill in their 3.6 engines, so why not the Traverse? Is the Traverse piston-ring package different enough that synthetic is not a great idea at first?
Both people I've talked to at the dealership service department suggested I wait until at least 6K before switching. I'm wondering how many timing chain issues the Mobil 1 engines have had or if the timing chain design has changed enough to cause these issues people are seeing.
With 4500 miles on it, our engine is probably as broken-in as it's going to get after our trip last week. Mobil 1 will be coming in another 1500 miles for sure.
