Go look up other very extensive threads talking about the oil life indicator. It is not simply a millage thing. It takes into account the temperature, how it is driven etc. It typically goes off between 7K and 8K. Some have claimed longer. It is usually about 7.5 K for me. Many on here go by it for changing the oil. Other do every 3K or 4K or 5K. Many past "lively" discussions on this topic. People either belive it works and go by it or say it is crap and change on their own schedule. I believe it works.
