Location: Green Bay, WI | Good tip, about changing the oil after the first 1000 miles. As I recall from the manual, even GM doesn't recommend that--but it certainly makes sense, for the reason you mentioned. As for the synthetic oil though, I think that is what came in our new engine. It's certainly what they recommended in the future when we picked up the car. I think they've gone to their dexos stuff for all their vehicles now, but I'm not sure if that's what they ship them with from the factory. I would hope that the oil life monitor in the vehicle would work on viscosity among other things--so if they did ship the vehicle with non-synthetic oil, the oil life indication would be reflected accordingly.
