One nice thing about fogging is the oil will help keep things lubricated and coated in the combustion chamber, and it will work it's way into and around the piston rings. I know many do not fog anymore, but I do feel there is benefit. If for some reason a ring gets stuck due to carbon, gum, or plain metal on metal, that could be very detrimental to the engine.
Could be as simple as removing the plugs, spray in, and rotate the engine a couple of times to let everything get coated... Those with 2 stroke engines have some oil in there already, although quite diluted, so fogging gives the extra coating. An etec will self store by injecting more oil into the chamber, thus coating it....
As for ethanol over winter, it will degrade just like premium will if not stabilized, and most stabilizers will have a certain amount of alcohol in them to bond with any potential water contaminants from condensation. And...you can always purchase 92 octane E10 as well, having a higher rating than premium non-ehtanol.
I truly do not see how condensation can form on the inside of the tank without external introduction as it is below deck usually and not really open to the air. Warm air has a very hard time traveling down a vent tube toward a colder environment, and even in the colder environment, the surrounding air will not have anywhere near the humidity level it can have in the summer months.
Fog the engine, fill and stabilize the tank with your fuel of choice, park it, and plan next year's trips!!
