Why Storage Preparation Matters
A classic car that sits improperly stored can suffer more damage than one that's driven regularly. Fuel goes stale, batteries die, tires flat-spot, and rodents move in. Whether you're storing your car for a Southern California winter or a multi-year restoration wait, proper preparation prevents costly problems.
Fuel System
Fill the tank completely to prevent condensation, which causes rust inside the fuel tank. Add a fuel stabilizer and run the engine for 10 minutes so the treated fuel reaches the carburetor or injectors.
Battery Care
Disconnect the battery and remove it from the car, or connect it to a quality battery tender. A dead battery left in a car can leak and cause corrosion.
Fluids
Change the oil before storage. Used oil contains acids that can damage engine bearings over time. Check coolant and brake fluid as well.
Tires
Inflate tires to the recommended pressure. If the car will sit for more than a few months, put it on jack stands to prevent flat-spotting.
Rodent and Pest Prevention
Mice love the warm, sheltered environment of a stored car. Block exhaust pipes and intake openings with steel wool. Place mothballs or dryer sheets in the interior and engine bay.
Cover and Environment
Use a breathable car cover, not plastic, which traps moisture. Store in a dry, climate-controlled space if possible.
How long can a classic car sit without being started?
With proper preparation, a car can sit 6–12 months. Beyond that, it's best to have someone start it periodically.
Should I start my stored car occasionally?
Only if you can drive it long enough to reach full operating temperature. Short starts that don't warm the engine can cause condensation.
What's the biggest storage mistake?
Leaving a battery connected and fuel untreated. These two cause more storage damage than anything else.
