They say this in the first paragraph: > follow the automaker's recommended service intervals. If I had a Prius I might change my oil every year. I instead follow the manufacturer (Ford) provided service schedule for my car. I have a feeling the 15 year old station wagon I commented regarding at the beginning of this thread is closer to my car than a Prius. Using a Prius maintenance schedule to be representative of the last 30 years of ICE cars doesn't make sense, you might as well compare with a lawn mower at that point.
