How to Store a Car Long-Term: Step-by-Step Guide for Safe Vehicle Storage

Storing your car for an extended period—whether you’re traveling abroad, storing a classic vehicle, or simply parking it through a long winter—requires more than just locking the doors and walking away. Without proper preparation, long-term car storage can lead to a dead battery, damaged tires, rusty parts, or even pest infestations. This guide walks you through the critical steps to keep your vehicle in top condition while it’s off the road.

Step 1: Choose the Right Storage Spot

Your car’s storage location matters:

Best: A climate-controlled garage
Acceptable: A regular garage with a breathable car cover
Outdoors: Use a high-quality, weatherproof cover and consider a tarp underneath to block moisture from the ground

Step 2: Clean Your Car Thoroughly

A clean car is less prone to corrosion and pest problems.

Exterior: Wash and wax to remove dirt and provide a protective layer.
Interior: Vacuum thoroughly and remove all trash to prevent odors and pests.
Undercarriage: Especially if you’ve driven in winter conditions, clean to remove salt and grime that accelerate rust.

Step 3: Change the Oil and Top Off Fluids

Used oil contains contaminants that can corrode engine components over time. Always change the oil and replace the filter before storing the car. Also, top off:

Coolant
Brake fluid
Transmission fluid

Step 4: Fill the Gas Tank and Use Fuel Stabilizer

Keeping your gas tank full prevents moisture from forming and rusting the inside. Add a fuel stabilizer to prevent the gasoline from degrading. After adding, run the engine for a few minutes to circulate the stabilizer.

Step 5: Take Care of the Battery

Batteries can lose charge over time, especially in cold storage conditions. Options include:

Disconnecting the negative terminal
Using a trickle charger or battery maintainer to keep it charged

Step 6: Protect the Tires

When a car sits, the tires can develop flat spots. To prevent this:

Inflate tires to the recommended pressure
Consider placing the car on jack stands
If possible, move the car slightly every few weeks

Step 7: Guard Against Pests

Rodents and insects can do major damage. Use these tricks:

Block exhaust pipes and air intakes with aluminum foil or steel wool
Use natural repellents like peppermint oil or mothballs
Avoid storing food or anything organic inside the vehicle

Step 8: Don’t Use the Parking Brake

Parking brakes can stick to the rotors over time. Use wheel chocks instead to keep the vehicle from moving.

Step 9: Check for Leaks and Fluid Seals

Even when parked, time can take a toll on your car’s internal systems. Inspect underneath the car for signs of fluid leaks before storage. Also:

Check all visible hoses and seals
Place a drip pan or absorbent pads under the car
Recheck seals and gaskets when taking it out of storage

Step 10: Final Preparations

Before walking away:

Plug the tailpipe
Cover the vehicle with a breathable cover
Take photos of the vehicle and note the steps you’ve completed
Make sure your paperwork is in order so you’re good to go when it’s time to drive again

Wrapping Up

Long-term car storage isn’t difficult, but it requires attention to detail. With proper preparation, you’ll avoid unnecessary repairs and ensure your vehicle is ready to go when you are. Whether you’re parking it for months or years, these steps will save you money and hassle down the road.
