Hello!
Bought an Impala w/ the 3.6L. It has 35k miles, I got an oil change done today. I asked what oil they used, but they replied with "full syn, dexos approved blah blah".
I'm sure its Mobil 1, looking at the part no. they used its 88865635 & of course an AC Delco oil filter. Are there any negatives to the free oil changes from the dealer?
I was going to install a fumuto valve and just do them myself.
