Normally, you should be able to go 3,000-7,000 on standard oil, and 5,000-10,000 on synthetic oil. Most newer Honda's suggest 10,000 miles on synthetic oil. They also state to change the oil every year, no matter what the mileage is. Find out if your light is triggered by mileage, or by testing the oil. If your light comes on at 3,000 miles, with less then a years driving (on synthetic oil), something is wrong with the motor. Talk with your dealership. I personally change regular oil at 4,000 miles, and synthetic at 6,000 miles.
