How often should I start a car that sits?

Regular Maintenance for Cars Left Idle

To ensure optimal performance and prevent potential issues, it is essential to maintain your car even when it’s not in regular use. One critical aspect of this is starting the engine periodically to maintain battery health.

Battery Maintenance

A car’s battery relies on regular use to stay charged. When a car sits idle for extended periods, the battery gradually discharges due to parasitic drains from electronic systems like alarms, clocks, and immobilizers.

Recommended Frequency

To prevent the battery from draining completely and causing starting problems, it’s recommended to start the car and run it for at least 15 minutes weekly. This allows the alternator to recharge the battery and maintain an adequate charge level.

Benefits of Regular Starting

• Prevent battery discharge: Regular starting ensures the battery stays charged, reducing the risk of a dead battery.
• Lubricate engine components: Starting the engine circulates oil, lubricating critical components and preventing corrosion.
• Test electrical systems: Running the car periodically allows you to check if electrical systems, like lights, wipers, and other accessories, are functioning properly.

Consequences of Neglecting Regular Starting

Prolonged inactivity can lead to the following issues:

• Dead battery: A completely drained battery will require jump-starting or replacement.
• Corrosion and damage: Reduced lubrication can cause corrosion and damage to engine components.
• Reduced fuel efficiency: A neglected car may experience reduced fuel efficiency due to increased friction and clogged fuel lines.

Tips for Maintaining Cars Left Idle

In addition to regular starting, consider the following tips:

• Use a battery conditioner or trickle charger to maintain the battery charge during extended periods of inactivity.
• Disconnect the negative battery terminal if the car will be unused for prolonged periods.
• Store the car in a cool and dry place to minimize battery discharge.

Remember, regular maintenance is crucial for ensuring your car remains in good condition, even when it’s not in regular use. By following these guidelines, you can protect your battery, prevent starting problems, and extend the lifespan of your vehicle.
