We've debated this subject a couple of times here on AFM. Dealers say do it at 3000 miles, some say wait 5000 miles, some say wait till the Oil Life Monitor tells you to do so. Car guys say change it out at 1000 miles, and some even say to change it out sooner than that because of the metal in the engine and because if you bought it off the lot, you don't really have an idea of just how long its possibly been sitting there and how other people have test driven it. Its all personal preference in my opinion. I'll probably change mine at either 1000 miles or 3000 depending on how I feel. I only drive close to 7k miles per year so every 6 months is when I'll do oil changes and the first one is free for me.
