I am a believer in filling the gas tank before storage to prevent condensation thus water from building up in the tank. Granted I only leave my car in storage 4 1/2 months each year but it is in a humid part of the country. I use a battery tender, Stabil and a full gas tank. While I have had a critter get into a car through the air intake once, I never tried the steel wool trick.
When I return, the car has always been ready to go. The battery tender is a nice touch because it keeps the computer alive and the battery charged but, I know you can't always do that in an outside storage lot.
Life is a journey, not a destination.
