I agree captinjohn.A picture paints a thousand words or in this case/the volume on tribology and wear of the Metal'sHandbook .Sounds all fine and dandy but nothing and I mean NOTHING beats first hand experience and hands on!!!!!!!!!
Besides that book is probably as old as the dinosaurs. Things are differen't these days and products change and so does the way we do things.Things that were proved years ago aren't necessarily the right way to do things today.
Sounds to me that the hundreds of guys out there including myself that are breaking in motors with synthetic super oils are dumber than a box of rocks just because we don't agree with the scientific book on breaking in metal.
Besides scientist didn't invent these model airplane motors,guys like you and me did,and guys like you and me regardless of what the manual says-------------- know best!
