For what it's worth, I was at my dealership today on a non-Crossfire matter and asked my usual service advisor, who seemed knowledgeable about the CF in our brief conversation, when I should bring the CF in for its first oil change and he said 3000 miles, repeating that figure at my request. He knows what kind of oil it takes and that there is no "break-in" oil. I am aware that my dealership, a 5-Star dealership, views Phoenix, and I assume properly so, as a "severe service" area because of the high summer heat and there is always a lot of dust.
