If you use the Amsoil Ea15K01 and the ASM oil (For 3rd gen Prius), then you can safely go 15,000 miles between oil changes. I drive 25,000 miles per year in my Prius. Amsoil backs up their products by a written warranty.
Thread: Oil Change Frequency. Oil Change Frequency I just purchased a new, 2006 Honda CR-V LX 4 wheel drive, automatic two days ago. The owners manual from Honda says change oil and filter every 10,000 miles. The dealer gave me a separate, generic service log that has entry boxes for every 3000 miles and the next service sticker they put on the windshield says service at 3,000.
