OK, first time changing it in my new car. I have heard 3,000 and 4,000 and even 5,000 miles. Also, I want to use Mobil 1 but the stores here only carry it in 5W 30 not the 5W 20. Any feedback appreciated

Putting a better exhaust is known and proven to improve performance. Changing out your oil at twice the rate needed doesn't improve performance.Silvr04GT said:Not to be an jerk, but if people used that philosophy with their cars no one would modify them. Example: Why change the exhaust it's what the engineers at Ford said we should use. The recommendations Ford makes is probably assuming you're not racing or anything like that as well. Having some extra protection isn't the worst thing in the world. And synthetic is oil is better anyway, not to start that whole fight again!
