I have this available to me too but only at the dealership where I bought my car which is over 50 miles away so I never used my free changes (plus I don't want to run the risk of them putting well oil in my car). I changed my oil first at 10k miles. I bought the car with 3k and they changed it at the dealership when I bought it. So I ran it 7k miles before changing it myself to 5w30 Royal Purple. I just changed my oil again at 14k (3k miles ago). I plan on running this oil every bit of 10k miles though. I am on Amsoil and its great! I also changed to their filter as well as their Tranny fluid. I also changed over to 10w30 since we live in a generally warmer region and that weight of oil will work better with hotter ambient temperatures. Changing the tranny fluid is defiantly noticeably smoother with shifts too.
