I have heard that myself, I was going to go through the process to become an amsoil distributor since work was slow, but decided not to do it in the end. I haven't used their products myself, but I suppose the oil change interval is just a mental thing for me. It would make me nervous to run 35000 miles without changing the oil or filter even though it has been proven to be ok. I'm a 3000 mile guy
