When the temperatures drop and the roads get salty, your prized classic car deserves better than sitting exposed to harsh winter conditions. Proper off-season storage protects your investment and ensures your vintage beauty fires up smoothly when driving season returns.
Whether you own a ’67 Mustang or a Porsche 911, following the right storage steps prevents costly damage from moisture, pests, and mechanical issues. Here’s your complete guide to storing your classic car during the winter to maintain that pristine look.
Prepare the Engine and Fluids
Begin your storage preparation by addressing the engine’s specific needs. Change the oil and filter before storage, as used oil contains contaminants that can corrode internal components over time when left idle.
Fill the gas tank completely and add a quality fuel stabilizer. A full tank prevents condensation from forming inside the tank, while the stabilizer keeps gasoline fresh for up to 12 months. Run the engine for 10 to 15 minutes after adding stabilizer to circulate it through the fuel system.
Check and top off all other fluids, including coolant, brake fluid, and power steering fluid. These fluids protect internal components even when the car isn’t running.
Address Tire Care
Tires and wheels complete the look of your car. And when you spend time on choosing wheels for your classic car, you want to know that they’ll remain protected over the winter. Long-term storage can cause flat spots on tires from the weight of the vehicle pressing down in one place. That’s why you should inflate the tires to the maximum recommended pressure, as they’ll naturally lose some air over time.
If possible, place your classic on jack stands to remove all weight from the tires. This prevents flat spots and reduces stress on suspension components. If jack stands aren’t an option, try to move the car slightly every few weeks to change the contact points.
Choose the Right Storage Location
Your preferred storage location can make a huge difference in protecting the car from temperature swings and humidity. If climate controlled storage isn’t available, ensure good ventilation to prevent moisture buildup.
Avoid storing your car directly on concrete floors, which can transfer moisture, and use a vapor barrier like plastic sheeting or invest in a quality car cover designed for long-term storage. A breathable cover prevents moisture buildup while protecting from dust and potential scratches.
Spring Awakening Done Right
Properly storing your classic car during the winter pays dividends when you’re ready to hit the road again. Your vehicle will start easier, run smoother, and maintain its value better than cars that sat neglected through the winter months.
