With most modern vehicles, you only need to change the oil once a year or around 10,000 miles. The every 3,000 miles thing is a way for dealerships and oil change places to make money. I'm pretty sure none of us current Insight owners has come close to needing their first oil change. The owner's manual gives a mileage amount, I think, but it also says change it when the MM says to. My car is at around 2500 miles and at 80% oil life.
