Changing the oil for storage

The logic behind filling the car up is that if you leave a large amount of air inside the tank the humidity will change with the weather and condensation will form. Because water is heavier than gas this condensation will find it's way to the bottom of the tank and cause rust. This is one reason gas tanks rust out.

There is a product called "gas dryer" that removes the water from the gas.
I forgot the brands, but they are also found in the gas additives area of the auto store.
For humid climates, I'd recommend running some thru before storing it, especially
with old cars that don't have sealed evapoation system gas tanks.
