Approaching 69,000 miles, our 2004 Toyota Prius needs another oil change. Hybrids are gasoline-powered cars at heart, so they still need this kind of regular maintenance. And it turns out the Prius oil and filter change is a very easy DIY job. At the end, you'll see how to reset the "Maint Reqd" light, the one that comes on when it's time to change your oil. This procedure applies to all 2nd generation (2G) Priuses, model years 2004 to 2009.
