Realize that there's some dispute on whether everything above is necessary:
-most people say periodic starting is NOT a good idea. But there are those "in the know" who say it should be done, pointing out that you NEED to start it long enough to get the engine fully warmed up...otherwise it's NOT good to start it for a short time only. And then others say do NOT start it at all; just keep it parked and properly stored. Or there are those who say you need to not only warm it up once in a while, but drive it to lubricate and get everything moving;
-most people tend to use fuel stabilizer however there are those who says it's a waste of money;
-99% of the people I've talked to or read their comments, agree with
Rruuff Day's suggestion: use a battery tender and NOT a trickle charger; but then you have others who say you should disconnect your battery and not bother with anything that charges the car. Then there are those who say disconnecting the battery will shut down all on-board computers and screw up your settings later in the Spring;
-everyone seems to agree that if your vehicle is exposed to mice/rodents, you should take preventive measures so they don't access your engine or interior compartments. So yes, stuff the exhaust pipes with something they can't chew through (ie. steel wool). People say NOT to use moth balls since the smell is difficult to get rid of (ie. not only a deterrent to rodents), and recommend things like dryer sheets. Some worry about rodents chewing through wiring or other materials, to gain access to your "under-hood area" and nest there; so some set baited traps for rodents and check them;
-some fussy people say park your vehicle with silica sand (stored in a porous bag/bags), which absorbs moisture. This should prevent that "musty smell" when you open your doors in the Spring after it's been parked awhile. Others disagree and say that's not necessary. Or some will park a vehicle with the windows open a crack, for air flow;
-some say to inflate your tires to their maximum, to prevent "flat spots" on the tires after a few months of being parked AND to prevent air pressure loss over time, making the tires flat or under-inflated. Others say that's not a good idea and you should take the tires off and store the vehicle on stands. Then some say storing it on stands and having no weight on the springs/shocks will be bad for them. Others say you should park the tires on some material which will supposedly prevent the flat spots;
-some say to store with a full tank of gas, to prevent the air space from attracting condensation, which could contaminate your fuel with water. Others say that's not a concern and a full tank will immerse the floating fuel gauge inside the tank and damage it, making for a costly repair later on;
-some say a car cover (soft felt-like material touching the car) is a must, to prevent dust or anything else from covering or harming your paint. Others say the opposite: the cover, if it rubs the paint, could cause damage, so best not to cover it with anything. Then there are different concerns about outside storage and covers: a loose cover will move around with the wind and more readily rub and damage the paint;
-some say to change your oil/filter just before parking it so it's stored w/o contaminants, whereas others say the opposite: wait 'til the Spring and do it then, otherwise your oil will break down while parked for months and not be up-to-snuff when you go to drive it in the Spring. Still others say ANY oil/filter change related to a parked vehicle, is a waste of money.
Confused now? I know I know, there's no 100% uniform "this is the way to do it" consensus. For me: battery TENDER; over-inflate tires; oil/filter change before parking; silica sand and windows up; anything rodent-related n/a since I'm in a garage w/o any evidence of rodents - ever; never start the car until Spring; fuel stabilizer and don't worry about tank being full (mine is a heated garage w/o any real temperature changes, so condensation potential n/a); GM OEM soft cover over top of a spotlessly clean car. You decide what works for you...good luck!
