I kept the RPMs below 3500 & did not go over 65 MPH for the first 1,000 miles. Other than that I just drove as the traffic flow would allow as I do anytime I drive an automobile. The Nissan recommendation from the manual says to not drive the same speed for periods at a time. I find/found this hard to do and really does not make sense. I'd hate to be behind a guy going from 30 to 50 to 30. I did the first oil change at 3,200 miles (Nissan recommends 3,750 mile intervals). If you have money to burn--it can't hurt to change your oil as often as you like.
