With the onset of fall & winter approaching here in the northeast and temps set to fall into the negative what if any procedures do you guys/gals take to keep the vehicle safe for the hibernation period it will be garaged. I'm old school and very suspicious of putting additives (stabil oil) other than gas into my gas tank. What are the pros & cons of using this additive if any?. Is there any other additional safety concerns we should be aware of for the long winter ahead. A friend of mine had a problem with mice getting into his engine compartment and having a good old feast on the electrics of his car in the past i remember. And that in itself caused all sort of problems for him when spring rolled around again.
