In the "old" days, you would put a vapor barrier on the floor of the garage, remove plugs and put a teaspoon of oil in each cylinder (turn over to coat cylinder walls), raise the car to relieve the suspension, and FILL the tank (and add Stabil). The reason to fill the tank, is to keep moisture out and thus preventing rust. BTW, Stabil or some similar product does work because untreated gas can and will break down. Oh, it is also a good practice to drain the oil and add fresh so the contaminate in the dirty oil don't ruin the bearings. Also, change oil before starting in spring to eliminate any moisture that has accumulated over the winter. Or you can do as I do and take it out through the winter whenever it is nice. Had mine out Sunday for an hour. Usually thirty days don't go by here in Wisconsin when you have conditions nice enough to take your car for a healthy spin. I always felt doing it my way was easier on a car as it keeps all the seals lubricated. YMMV
