How Often Should You Drive A Car In Storage

The question of how often to drive a car in storage isn't a simple one. It’s not just about preventing a dead battery; it's about preserving the intricate network of systems that keep your beloved machine running smoothly. Let’s delve into the nuances of short-term and long-term storage and the crucial role regular drives play in automotive longevity.

Why Driving Matters for Stored Cars

Leaving a car dormant for extended periods invites a host of potential problems. Think of it like this: your car is designed to be a dynamic system, not a static display piece. Regular operation keeps fluids circulating, seals lubricated, and prevents components from seizing or corroding.

One of the primary concerns is the battery. Even with a trickle charger, self-discharge occurs. A regular drive allows the alternator to fully recharge the battery, extending its lifespan and preventing the frustration of a no-start situation. Consider the impact of a deeply discharged battery on modern cars with complex electronic systems. These systems rely on a stable voltage, and repeated deep discharges can corrupt software or damage sensitive components.

Next, consider the fluids. Engine oil, coolant, brake fluid, and transmission fluid all degrade over time, even when the car is not being used. Oil can settle and become acidic, potentially corroding internal engine components. Coolant can lose its anti-corrosion properties, leading to rust and scale build-up. Brake fluid is hygroscopic, meaning it absorbs moisture from the air. This moisture can cause internal corrosion in the braking system and reduce braking performance. Regular driving circulates these fluids, keeping them fresh and preventing them from settling or degrading.

The tires are also vulnerable. Sitting in one position for extended periods can cause flat spots, leading to vibrations and uneven wear. Furthermore, tires slowly lose air pressure over time, and underinflated tires are more susceptible to damage. A drive allows the tires to heat up and regain their shape, and it gives you an opportunity to check and adjust tire pressure.

Finally, consider the mechanical components. Seals can dry out and crack, leading to leaks. Brakes can corrode and seize. Internal engine parts can become sticky or gummed up. Regular driving keeps these components moving, preventing them from seizing and ensuring they remain lubricated.

Short-Term vs. Long-Term Storage

The frequency with which you should drive a stored car depends largely on the duration of storage. Short-term storage might be a few weeks to a couple of months. Long-term storage, on the other hand, implies periods of several months or even years.

For short-term storage (up to 2 months), aim to drive the car for at least 15-20 minutes every two weeks. This allows the engine to reach operating temperature, circulate fluids, and recharge the battery. Ensure you drive at varying speeds to properly exercise the transmission and brakes.

For long-term storage (over 2 months), more stringent measures are necessary. While a drive every few weeks is still beneficial, consider taking the car for a longer drive, perhaps 30-45 minutes, every month. Before putting the car back into storage, top off all fluids, including fuel, and consider adding a fuel stabilizer to prevent fuel degradation. It’s also wise to overinflate the tires slightly to prevent flat spots.

The Ideal Storage Drive

The ideal storage drive isn't just about putting miles on the odometer. It's about ensuring all systems are properly exercised.

• Warm-up: Allow the engine to fully warm up to operating temperature. This ensures proper lubrication and burns off any condensation in the exhaust system.
• Varying Speeds: Drive at varying speeds to exercise the transmission and brakes. Avoid just cruising on the highway; include some stop-and-go driving and gentle acceleration.
• Braking: Apply the brakes firmly several times to clean off any surface rust and ensure they are functioning properly.
• Cornering: Take some gentle corners to circulate power steering fluid and prevent seals from drying out.
• Cool-Down: Allow the engine to idle for a few minutes before shutting it off. This allows the turbocharger (if equipped) to cool down and prevents heat soak.

Beyond the Drive: Other Considerations

Driving is just one aspect of maintaining a car in storage. Other important considerations include:

• Cleanliness: Thoroughly clean the car inside and out before storage. This prevents dirt and grime from damaging the paint and interior surfaces.
• Cover: Use a breathable car cover to protect the paint from dust, scratches, and UV damage.
• Pest Control: Take measures to prevent rodents and insects from entering the car. This may include using mothballs or other pest repellents.
• Secure Storage: Store the car in a secure, dry location away from direct sunlight and extreme temperatures.

By understanding the reasons behind regular drives and implementing a comprehensive storage strategy, you can ensure your car remains in top condition, ready to hit the road whenever you are.

Remember to consult your owner's manual for any specific recommendations regarding storage for your particular make and model. And when in doubt, consult with a qualified automotive technician.
