Yeah, I read it. It was posted on the Amsoil web site. Besides being biased towards Amsoil, it was just plain wrong. It tended to say that 3K oil changes were a conspiracy by big oil. It did not account for oil change frequency being related to the vehicle, engine, usage, sump size, oil brand/type, and climate, among other factors. Those who follow this forum over the months will see right through this article. Give us some credit, Amsoil, we're not going to fall for that load of crap.
