How often should I change the oil? on 2004 Ford Freestar

I have been using 5w-30 oil and changing the oil every 3,000 miles. I drive approximately 13,000 miles every year. Am I changing the oil too often?

I probably do it on that schedule as well,but most think that every four or five thousand would be perfectly fine.I would also think that your vehicle requires 5/20.
