You already said that you drive it easy, so if it looks in good condition, just go with the miles, and don't worry about the months.
3K / 3mo is a sham. That said, once you introduce your oil to your engine, and all that it goes through...it's not unreasonable to say that it needs to be changed at least once a year, if not 2-3 times.

I read somewhere that the time to change your oil basically goes around the winter months if you drive it a lot. Late fall, early spring, since that's when the oil will collect and retain moisture due to the colder temps not letting the oil get hot enough to burn it off.
