Vehicle Storage Tips

Cars are meant to be driven. Leaving a vehicle unattended for a long period of time can cause something akin to automotive atrophy, a slow deterioration of the vehicle that can create problems when you try to drive it again. Rust and corrosion can form on the body or inside critical components, gum and varnish can clog the fuel system, sludge and acids can form in the engine oil, mildew can grow in the interior, and constant sunlight can slowly fade the paint and deteriorate vinyl, leather, and rubber parts. That's why if you need to store your vehicle—whether for the winter or because it can't be driven for an indefinite period of time—certain precautions should be taken before you put it into mothballs.

Get It Covered Leaving a vehicle unattended for a long period of time can cause something akin to automotive atrophy.
The best place to store a car is out of the weather, preferably inside a building that's cool, dark, and dry. If you don't have a garage, look into renting one. If this isn't possible, a reasonable alternative is to store it inside a portable enclosure, such as in a car bag or portable garage. If the vehicle will be completely sealed from outside air, place a couple bags of desiccant inside the enclosure with it to absorb trapped moisture. However, if the vehicle needs to be stored outside without an enclosure, at least cover it with a quality car cover that has thick, multi-layered fabric.


Prior to putting the vehicle into storage, a few precautions will help keep it in good shape. The fuel system, for instance, can be a prime source of problems. If the car is stored with an empty tank, moisture can condense inside the system and cause rust and corrosion. On the other hand, if the car is stored with fuel in the system, the gas can gradually break down, forming gum and varnish. To help keep gasoline from deteriorating, pour a fuel stabilizer into the tank. Be sure to drive the car for about 10 miles after adding the stabilizer to make sure it gets circulated throughout the system. Normally, it's best to leave the tank full. However, if the vehicle will be stored in an enclosed location where gas fumes could be a problem, empty the tank about half way.

Additional Prep
Other preparations that should be done before storing a vehicle:


> Change the oil and filter. Used oil contains acids, moisture, and other combustion byproducts that, over time, can cause corrosion inside the engine.


> Fill the engine with fresh oil and then drive the vehicle for a few miles to make sure the new oil gets thoroughly circulated.


> Pull the spark plugs and pour about a teaspoon of oil into each cylinder. Then replace the plugs. This will help coat the cylinders to prevent rust.


> Seal off engine openings with absorbent cotton to keep moisture out.
