Honad, I don't think it is very true. While I had my Si for 3 years and 21k miles, when I did drive it, I drove it fast and hard. My oil was only changed 2 times as they told me to do so between 15%-0%.
It has just become more common knowledge that you don't need an oil change every 5k.
Not sure if anyone listens to Car Talk but one of the brothers has an old 80's car that has had the same oil in it for 20+ years now as a pseudo experiment and last I heard it was still working just fine. He's been amazed that the engine hasn't seized up yet, which is understandable.
