    Engine really doesn't matter, it's really the tranny that needs some miles on it.

    ^^ I changed ALL my fluids and filter to AMSOIL products at around 1500 miles. Some say it's a good idea to do this on a new vehicle, and some think it's not necessary. But in my case I felt it was cheap insurance on this CTS-V.

    I had the dealer swap out the rear diff fluid at 2K miles under warranty. There is a TSB for the noisy rear diff in case any of you want to take advantage of the TSB.

    Engine and trans are still factory fill. I will change out my engine oil at 5K miles most likely as the factory GM oil filter highly loses it's filtration capabilities at 5K miles according to a GM dealer tech that opened up filters at all different mileage intervals and he showed me why you should never run the factory GM oil filter past 5K miles.

    I won't be changing out the trans fluid as the GM Dexron VI is a very good synthetic fluid. I won't change the trans fluid until the service is actually needed.
