How often should I turn on an unused car?

Maintaining an Unused Car: Frequency of Engine Use

If you possess an unused car, it’s crucial to take proactive measures to preserve its condition. One key aspect of maintenance is determining the optimal frequency for turning on the engine.

Battery Health

Batteries gradually discharge over time, even when not in use. By starting the engine, you replenish the battery’s charge and prevent it from going completely flat. To maintain optimal battery health, aim to turn on the car every two weeks.

Condensation Buildup

Prolonged inactivity can lead to condensation buildup within the engine and other components. Moisture can cause rust and corrosion, potentially damaging sensitive systems. Running the engine periodically helps circulate air and reduce moisture accumulation.

Recommended Frequency

For optimal results, strive to start your unused car once every two weeks. This frequency allows the engine to reach full operating temperature, which thoroughly disperses condensation and ensures battery longevity.

Acceptable Minimum

If scheduling permits only weekly engine starts, it’s acceptable but not ideal. Bi-weekly maintenance is strongly recommended for all unused vehicles to minimize potential issues.

Steps to Take

When starting an unused car, follow these steps:

• Check fluid levels (oil, coolant, brake fluid)
• Turn on the air conditioner for a few minutes
• Drive the car for at least 20 minutes, allowing the engine to reach full operating temperature

Additional Tips

• Consider using a battery tender to maintain the battery charge during extended periods of inactivity.
• Fill up the gas tank to prevent condensation in the fuel system.
• Park the car in a dry, well-ventilated area if possible.

By adhering to these recommendations, you can minimize the negative effects of inactivity on your unused car and ensure its longevity. Regular engine starts will promote battery health, reduce condensation buildup, and preserve the overall functionality of your vehicle.
