I don't think GM uses special break-in oil as Honda does.

Yeah, that's what kind of threw me... Same motor, but different break-in process. And only "if" you are going to track it should you add the extra oil change.
Not only have I never heard of GM using any special additives in the oil in any of their cars, that's what what kind of "sold me" on the premise that there weren't any in this engine. I opted to do the early oil change because I wanted to visibly inspect the clarity of the oil right out of the gate. I was surprised at how dark the oil was after 600 miles, but it did not appear to be carrying any contaminants. Even after the drain pan sat overnight, there wasn't anything left sitting on the top after the oil had drained away.
