RE: New Engine Break In
If you are happy with the manual and 1:100 ratios, so be it.
Tests have shown, that best fuel economy was obtained with 1:30 fuel oil mixtures or even more oil. That means, that at these ratio's, friction is lowest.
If you run more friction, the engine gets hotter, wears faster. That's a fact of life. The piston also has less heat transfer, so runs even hotter (air cooled!) Heat flow from piston jacket to cylinder is the only thing that keeps the piston from melting. If the piston crown inside is black, you are close to desaster. If it gets ashen (death ash), You are courting it. Before making all the statements that you do, I would rather not hide behind Graig's broad back, but inspect my engine so I know what I talk about.
If you are happy with 1: 100 and shorter engine life, so be it. I would not do it your way, and a little oil mist out of the exhaust system does not bother me. That is what keeps my engines alive.
