Sta-bil
We have a '97 Olds LSS with the supercharged 3.8. It has been stored every winter since new. All we do is spread some Bounce dryer sheets around inside, Fill the tank with gas and the appropriate amount of Sta-bil and put the car away after a 20 mile run. The battery gets disconnected. We've never had a problem. We will do the same with the Corvette and have also bought a battery tender type charge just for a little more insurance. We have found from our cottage experience that mothballs just stink the place up and do not keep the mice out. So far the Bounce sheets have kept the mice away and it has been six or seven years since we started that in the cottage.
