Usually try to bump up the airpressure, put battery on Trickle charger,Do not start the car during winter, Keep full tank of gas along with Stabil gas treatment, Use mothballs or somthing to put around the car, Block off aircleaner and exhaust exits...Spray engine completly with WD-40 all over, including wires and engine itself.. With todays tires as long as airpressure is bumped up, you wont need to suspend car in air with jackstands,
