Whether you are heading south for the winter, taking an extended business trip, or simply putting a summer performance car away for the season, storing a vehicle requires more than just parking it and walking away. Without the right preparation, a car sitting idle can suffer from flat-spotted tires, a dead battery, degraded fuel, and even pest infestations.
Following a few long-term car storage tips can mean the difference between a car that starts up perfectly and one that requires a flatbed tow to the shop. In this guide, we will cover the essential steps to protect your investment during its “hibernation” and how Amayak Auto can help you prepare.
1. Clean It Inside and Out
It might seem strange to wash a car you aren’t going to drive, but this is the most critical first step.
- The Exterior: Bird droppings, tree sap, and water spots are acidic. If left on the paint for months, they can permanently etch the clear coat. A thorough wash and a high-quality wax provide a protective barrier against dust and moisture.
- The Interior: Crumbs or wrappers might seem harmless, but they are a beacon for rodents. Vacuum every crevice and ensure no food or organic material is left behind.
2. Change the Oil and Filter
If you are storing your car for more than 30 days, you should change the oil right before you park it. Used engine oil contains contaminants, moisture, and combustion byproducts (acids) that can settle and cause internal corrosion over time. Fresh oil ensures that the internal components are bathed in clean, pH-balanced lubricant.
3. Manage the Battery
A car’s computer and security systems draw a tiny amount of power even when the engine is off. Over a few weeks, this will drain the battery to a point where it can no longer be recharged.
- Battery Conditioner: Also known as a “trickle charger,” this device monitors your battery and provides just enough power to keep it at 100% without overcharging it.
- Disconnecting: If you don’t have access to power, you can disconnect the negative battery terminal. However, keep in mind this may reset your radio presets and clock.
4. Protect the Fuel System
Modern gasoline contains ethanol, which absorbs moisture from the air and can turn into a “varnish” or “gum” inside your fuel lines and injectors if left to sit.
- Fill the Tank: A full tank leaves less room for air and moisture to accumulate, preventing rust on the tank walls.
- Fuel Stabilizer: Add a high-quality fuel stabilizer to the tank and drive the car for 10-15 minutes to ensure the treated fuel reaches the engine’s fuel rail and injectors.
5. Tire Care and Pressure
When a vehicle sits in one spot for months, the weight of the car can cause the tires to develop “flat spots.”
- Over-Inflate: Increase the tire pressure by 5-10 PSI (without exceeding the maximum on the sidewall) to help the tire maintain its round shape.
- Tire Cradles: If storing for more than three months, consider using curved tire cradles or “flat-spot protectors” to distribute the weight more evenly.

If you aren’t sure if your car is ready for the winter, bring it to us for a “Storage Readiness” check. We can change your fluids, test your battery health, and give you personalized long-term car storage tips specific to your model. At Amayak Auto, we treat your car with the same precision and care that our founder, Amayak, instilled in us decades ago.
Conclusion: The “Wake Up” Routine
When it’s finally time to take your car out of storage, don’t just turn the key and drive. Check the tire pressures, look under the hood for any signs of rodent nests (like chewed wires), and check the ground for new leaks. Let the engine idle for a few minutes to allow the oil to circulate before heading out for your first drive.
Frequently Asked Questions (FAQs)
1. Should I start my car and let it idle once a week during storage?
No. This is actually counterproductive. Idling the engine for a few minutes doesn’t get the oil hot enough to burn off moisture, and it actually creates more condensation in the exhaust. It’s better to leave it off entirely unless you can take it for a 20-minute drive.
2. Is a car cover necessary for indoor storage?
A breathable car cover is a great idea even indoors. It protects the paint from dust and prevents accidental scratches if someone walks past the vehicle. Avoid plastic covers, as they trap moisture against the paint.
3. How do I keep mice out of my stored car?
Rodents hate strong scents. Many owners find success by placing dryer sheets or cotton balls soaked in peppermint oil in the cabin, trunk, and even the engine bay (just remember to remove them before driving!). You can also plug the exhaust pipe with steel wool to prevent them from nesting inside.
4. Should I put my car on jack stands for long-term storage?
For modern tires, jack stands are usually unnecessary unless the car will be sitting for more than six months. If you do use them, make sure they are placed on the proper frame points to avoid damaging the suspension components.
5. Does the car need an oil change after storage, too?
If you changed the oil right before storage and the car was in a climate-controlled environment, you are usually fine to drive. However, if the car was stored in a damp or unheated garage for several months, we recommend an inspection at Amayak Auto to check for any moisture contamination in the fluids.
