Introduction
Many car owners in Ontario and elsewhere have vehicles that are not driven every day. It could be a second car, a seasonal vehicle, or one you reserve for specific trips. While it may seem logical that less driving means less wear, the opposite is often true — cars that sit idle develop more issues than those driven regularly.
Batteries lose charge, tires develop flat spots, fluids break down, and pests can sneak inside. Cars are designed to be driven, and when they’re not, special care is required to avoid costly repairs. Here’s how to maintain a car that isn’t used often so it’s ready whenever you need it.
Why Maintenance Is Important for an Infrequently Driven Car
A car left alone for some time may appear okay on the surface, but several mechanical problems may be occurring silently. Lack of use affects batteries, tires, brakes, and fuel systems. Correctly maintaining an unused automobile will allow you to prevent accelerated breakdowns and to keep the car safe for use once in a while. If you decide to sell or trade in the car one day, that car is more valuable because of your care and attention.
1. Keep the Battery Charged
Car batteries naturally discharge when not in use. If left idle for weeks, the battery may not have enough power to start the car. To prevent this:
-
- Drive the car for at least 20 minutes every two weeks.
- Use a trickle charger or battery maintainer if driving isn’t possible.
- Disconnect the negative terminal if the car will sit for more than a month.
2. Protect the Tires from Flat Spots
When a car stays in one spot too long, flat spots can form on the tires. This leads to rough rides and reduced tire life. Here’s what you can do:
-
- Move the car slightly every few weeks.
- Keep tires inflated to the recommended pressure.
- Use jack stands to take the weight off the tires if the car is stored for months.
3. Protect Against Rust and Corrosion
Ontario weather — especially in winter — accelerates rust and corrosion in idle vehicles. Moisture settles on brakes, exhaust systems, and body panels. Reduce the risk by:
-
- Parking in a covered garage or using a weatherproof car cover.
- Washing and waxing the vehicle before storage to remove road salt.
- Applying a protective spray lubricant on exposed metal surfaces.
4. Maintain Fluid Health
Even when idle, fluids degrade, absorb moisture, and can cause corrosion. To keep systems safe:
-
- Change oil and filter if the car will be unused for months.
- Check coolant and brake fluids regularly.
- Use a fuel stabilizer if the car won’t be driven for over a month.

5. Keep Brakes in Working Order
Moisture can cause brake rotors to rust, which may lead to sticking or poor performance. Protect your brakes by:
-
- Moving the car forward and backward every few weeks.
- Avoiding the parking brake during storage — use wheel chocks instead.
- Inspecting brakes before driving after long storage.
6. Keep the Interior Fresh and Pest-Free
Idle cars attract pests, dust, and mould. Prevent costly cleaning and keep your cabin comfortable with these tips:
-
- Vacuum carpets and upholstery before long-term storage.
- Use moisture absorbers to prevent mould and mildew.
- Seal openings and remove all food or wrappers to deter rodents.
- Leave windows slightly open (in a secure location) for airflow.
7. Run the Engine Periodically
Running the engine every two weeks helps circulate oil, keep seals lubricated, and maintain your A/C system. Let it run for 15–20 minutes in a well-ventilated area to avoid harmful exhaust buildup.
Don’t Forget Legal Requirements
Even if you rarely drive, Ontario law requires you to have valid registration and insurance. Contact your insurer to ask about storage coverage options, which may lower your rate.
When to Seek Professional Help
If your car has been inactive for several months, schedule a professional inspection before driving it. Experts can check for hidden issues such as fuel degradation, brake wear, or electrical problems.
Final Thoughts
Preventive maintenance may seem unnecessary for a car you rarely drive, but it saves time and money in the long run. By following these tips, you can protect your battery, brakes, tires, and fluids — while keeping rust and pests at bay. With proper care, your car will always be ready for the road, whether it’s a quick errand or a weekend getaway.
Frequently Asked Questions
1. How long can a car sit unused before problems start?
Most cars start developing issues after about two weeks of inactivity. Batteries may lose charge, tires can develop flat spots, and fluids begin to degrade. Beyond a month, problems become more noticeable, especially in colder climates like Ontario.
2. Should I store my car with a full tank of gas?
Yes. Keeping the fuel tank full helps prevent condensation and moisture buildup, which can lead to rust in the fuel system. If the car will sit for more than a month, adding a fuel stabilizer is recommended.
3. Is it better to disconnect the battery or use a trickle charger?
If your car will be unused for several weeks, a trickle charger is the best option since it maintains the battery at a safe charge level. Disconnecting the battery is effective, too, but it may reset electronics and require reprogramming later.
4. Can I cancel my car insurance if I’m not driving the vehicle?
In Ontario, you cannot legally cancel insurance if the vehicle is still registered. However, you can ask your insurer about storage coverage or reduced-rate options if the car won’t be on the road for months.
5. Do I need to start my car every week if I’m not driving it?
Starting the car once every two weeks and letting it run for 15–20 minutes is usually enough. Weekly starts aren’t necessary unless you want to be extra cautious. Just ensure it runs in a well-ventilated area.
6. Is it okay to leave my car parked outside for months?
Yes, but it’s not ideal. Outdoor storage exposes the car to rust, paint damage, and pest issues. If a garage isn’t available, invest in a high-quality weatherproof car cover and park on a dry surface, not grass or soil, to reduce moisture damage.
7. How do I prepare my car for long-term winter storage in Ontario?
Before winter storage, wash and wax the car, change the oil, top up fluids, inflate tires, and add a fuel stabilizer. Store it indoors if possible, or cover it with a breathable, weatherproof cover outdoors.
