My first oil change was at 2400 miles because I was getting ready for an 1800 mile trip. Now I have 4700 miles and plan on changing oil at 6000. Then 10,000.

I haven't decided from there, but wiil probably go every 5000 miles. It will also depend on how dirty the oil seems to get by visual inspection. I used to change oil every 3000 miles on my other vehicles.
