I would think an automotive, or even a lawn mower, would be an even worse place to dump a bunch of teflon since the problem with it is the same as already stated in a previous message. The teflon continues to build up and can eventually block either the filter or oil passages. While it MAY provide some benefit due to accidental oil loss, it could also cause the same problems due to oil starvation which you would never find since the plug is still in the engine, the dip stick shows proper oil fill and there are no leaks.

Thanks, but NO THANKS! I'll stick to properly engineered lubes for all of my engines large and small.
