Ah yes, the Great Car Care Nut. I just watched the first video, which he just posted three hours ago.
It is very persuasive, and provides specific video/experience.
Typical oil change intervals should be at 5k miles or 6 months, with oil of known quality and value. This is to avoid such things as frozen oil control rings.
Watching this video was 45 minutes very well spent IMV.
Watch the second one I posted from him. He goes into more detail about the oil control rings as well and low tension rings, etc....
