Well, Just this year I got rid of a 30 year old merc tower of power, 115 outboard. And it still ran, and we never fogged that engine. What I will say is that it was stored in an unheated garage most of those 30 years, and we did run the gas out of the engine. But that was all the maintence she ever got for winterization. (even when I had a marina store it. They told me they didn't fog the engine)

With that said some notes here, that engine was built with the idea of running dry in mind. Second it was a two stroke which means the cilinders where lined with 2 cycle oil already.

My suggestion to people is do what makes you most comfortable. Although as someone noted to much fogging oil is not a good thing. A relative of mine I believed shortened the life of his motor because he fogged it to heavy every year which resulted in a lot trouble each spring getting running.
