I have been working with race engines long enough to know this and it would surprise me if they are using synthetic oil at start up. Recommending you use it does not mean it has it in now. I don't know.
I'd bet my car on it, this car 100% comes with Mobil 1, as does the C6, as did the C5. And even the 4thgen LS1 cars did....
