Winter coming, need advice for this newbie...

I fill the tank and add a bottle of Seafoam. I change the oil with the same 20W50 Amsoil I always use. I park it in a cold, unheated storage unit. If the weather is warm and no snow, I may get the car out and drive it a bit. Otherwise, It sits in storage on it's tires until spring when I pull it out and drive it home. Let's face it, it's going to be five months tops. What do you really need to do for that little time?
