So I talked to my dealer while in for my free change. They said that the move to 5000 was just because of how many questions they got from people unsure if they should be changing 3500 or 7500. Apparently if you use a quality synthetic and have the dealer change it they will warranty 7500 mile changes on the car still unless the dealer thinks you should move to the 5000 or 3500 plan.
SO really they are leaving it up to the dealers descression.
